Yes. Its very easy to do using XSLT. Just I want try to do any
possibility using XQuery.

let $input-document := 'splitfile.xml'
let $collection := 'file///D:/temp'

     for $term-data in doc($input-document)/root/row
                let $term-name := $term-data/Term/text()
        let $documentname := concat($term-name, '.xml')

The example uses ddtek:serialize-to-uri() which is a DataDirect vendor
extension. It doesn't use copy().

You could use similar logic in Saxon (and any other product that supports
XQuery Updates) by enabling XQuery Update and using the put() function.

There is no function called copy(). What made you think there was, and what
did you expect it do?
 
XQuery doesn't really have a way to write multiple result documents. You
could do it by returning a sequence of document nodes to the application,
and then having the Java application serialize them and write them to disk,
but it would have to know where to write them. It's easier to achieve this
in XSLT:
 
<xsl:template match="row">
  <xsl:result-document href="{Term}.xml">
     <xsl:copy-of select="."/>
  </xsl:result-document>
</xsl:template>

This (multiple output files)  is a data direct specific feature.

If you'd like to use saxon and XQuery but avoid writing custom java code, 
you might consider xmlsh.
www.xmlsh.org

The command "xsplit" will split documents of the sort you describe.
http://www.xmlsh.org/CommandXsplit

Combined with the the command  xmove
http://www.xmlsh.org/CommandXmove

Will rename the files in bulk based on an xpath expression.


But the xslt example Mr. Kay suggested looks easier :)

( fyi you can run xslt as a post process to your xquery code in your 
language of choice, including xmlsh).
   xquery ... | xslt ...

There is a slight improvement, to the solution I posted earlier. The
earlier solution, didn't check that "id" attribute belonged to "chap"
element (I think, this was mentioned in your requirement).

The solution below has this improvement.

declare namespace local = "http://example.com/functions";

declare function local:copy($element as element()) {
  element {node-name($element)}
    {$element/@*[../self::chap and not(name() eq 'id')], if
(local-name($element) eq 'chap') then
	                                  (attribute id {
concat($element/preceding::bn, '_', $element/@id) }) else (),
     for $child in $element/node()
        return if ($child instance of element())
          then local:copy($child)
          else $child
    }
};

local:copy(doc('test.xml')/*)

The following seems to work:

declare namespace local = "http://example.com/functions";

declare function local:copy($element as element()) {
  element {node-name($element)}
    {$element/@*[not(name() eq 'id')], if (local-name($element) eq 'chap') then
	                                             (attribute id {

        return if ($child instance of element())
          then local:copy($child)
          else $child

Would someone show me what the syntax is for replacing the value of an
attribute node?
<art>
<tit>Title here</tit>
<bn>46793</bn>
<p>some text here</p>
<chap id="ch1">
<p>some text here</p>
</chap>
<chap id="ch2">
<p>some text here</p>
</chap>
</art>

Output

<art>
<tit>Title here</tit>
<bn>46793</bn>
<p>some text here</p>
<chap id="46793_ch1"> <!-- add <bn>46793</bn> in id value. -->
<p>some text here</p>
</chap>
<chap id="46793_ch2">
<p>some text here</p>
</chap>
</art>


I want using xquery to change <bin> number value add in all chap id.


Thank you!

Ricardo

o pessoal citou algumas  funções q vc poderia usar  , mas  se for o caso  vc
pode criar  algo customizado tambem , usando  o eixo  ancestor-or-self e  as
propriedades name() ou local-name()

algo tipo :

for  $entrada in doc("testeGroup.xml")/*   return

    let $elementoProcurado := 'B' , $posicao :='1'
    for $i  in $entrada//*[name()=
$elementoProcurado][position()=1]/ancestor-or-self::node()  return
        if (name($i)!=$elementoProcurado) then
        concat(name($i),'/')
        else
        name($i)


passando como entrada o nome do elementoe  a posição   dele....

espero ter ajudado

-------------------

Ricardo

You can use  a  function  from  functx  or  try to make a  customized  one
using   ancestor-or-self  axis  , and  name()  or local-name() properties...
something like:

for  $entrada in doc("testeGroup.xml")/*   return

    let $elementoProcurado := 'B' , $posicao :='1'
    for $i  in $entrada//*[name()=
$elementoProcurado][position()=1]/ancestor-or-self::node()  return
        if (name($i)!=$elementoProcurado) then
        concat(name($i),'/')
        else
        name($i)

Hi Ricardo,

You can use the functx library that contains such functions:
http://www.xqueryfunctions.com/xq/functx_path-to-node.html.
Functx is very easy to deploy in your XQuery app since it is not bound
to a specific XQuery engine or library.

Best regards,

William

Thanks to all!
I'm using JAVA.
The best approach is use XQuery API for Java (XQJ)?

Since you posted to xquery-talk I think we all assumed you were using XQuery not native java.

If your not already using XQuery in your app, I might suggest you implement this in pure java, its not that difficult.
But how to do it will depend on what XML API your currently using.

But if you plan on using XQuery, the first choice is to pick a Java XQuery implementation (before picking the API).
The API interface (XQJ) doesn't actually provide an implementation.

My personal favorite for embedded xquery in java is Saxon,  www.saxonica.com
And if your using Saxon I'd suggest its S9API over XQJ

Thanks to all! 
I'm using JAVA.
The best approach is use XQuery API for Java (XQJ)?


Thanks!

    Hi Ricardo,

    You can use the functx library that contains such functions:
    http://www.xqueryfunctions.com/xq/functx_path-to-node.html.
    Functx is very easy to deploy in your XQuery app since it is not bound
    to a specific XQuery engine or library.

That's not possible, you can't have an empty namespace, and there is
no equivalent of xpath-default-namespace.

Instead you either move the xpath outside the containing element,
either as a function or a variable:

let $num := count(collection("/db/quotes")/quote)
return
<html xmlns="http://www.w3.org/1999/xhtml">
{$num}
</html>

or you leave off the default namespace and generate well formed html,
changing your output to xhtml as the last step in the process, using
either a transform or a processor extension.

Not quite my problem, I think. I want to use an XPath expression that
queries a non-namespaced source document inside a default namespaced
output element. Do I now have to bind a prefix to no namespace? e.g.

declare  namespace pre "";

<html xmlns="http://www.w3.org/1999/xhtml">
{
let $num := count(collection("/db/quotes")/pre:quote)
return $num
}

Yes, but I got tired of that years ago. :-)

This, however, is a whole new level of insanity. Who thought it would
be a good idea to break practice with XSLT, every single XPath
implementation on the planet, and years of experience and
documentation?

There's an argument to be made for default namespaces applying in path
expressions, but the time for that argument to be made was 1998. Once
the choice was made, the cost of switching was far higher than any
incremental improvement you might make. Stare decisis isn't just for

David,

xmlsh seems to me a fascinating approach, and I wonder if the W3C has considered developing a related standard: If it has decided against it I would like to know the reasons. It is simply strange that we XML-minded people have on the one hand a deep conviction about the value of structured information; and on the other hand accept it meekly, day by day, that our workhorse - the unix shell - consumes and delivers lines of text only... that it delivers, say, the result of a find command in a pityfully unstructured way to be parsed... It is an anachronism.

The basic tools concept, as you explain it on the philosophy page of xmlsh, is convincing, and it is a background before which the worth of interoperability of "small programs" gets very clear. If one accepts the tools concept as a general idea, I think it is but a little step to the thought that the interoperability of XQuery queries may be an interesting issue. 

What concerns the interaction of queries in the context of xmlsh I have not yet quite understood what is supported or not (yet?) supported. Can one, for example, profit from pipes in order to link two queries? If you gave me a hint where to look, or said a few words in explanation, I would be grateful.

You might want to look at xmlsh which was designed to solve this problem of managing the efficient interactions of many xqueries (as well as may non-xquery XML and non-xml pieces of a larger integration),
although perhaps not in the way you express.

But it still changes the default both for constructing new elements and for accessing existing ones. What the user wants here is different defaults for the two cases.

I do not believe it has been considered -- generally, W3C Member
organizations come to us (W3C) and propose work items; often we
then arrange a public Workshop, and if that goes well, start a
Working Group. 

Years ago I worked on an SGML Shell (never released, it used
proprietary software) and tried to get some people interested.

But then you are using one particular implementation...
And using eXist to handle incoming forms seemed to involve
some weird kludgery with eval() last time I looked, although
that was a while ago, and I didn't look too deeply because
I'd already written my own little framework.

I'd really like to see more standardization - even informally -
at the level "beyond the query", because I think we (the
XQuery world) are missing out on a lot of opportunities for
more adoption.

I don't think XProc is the answer - it might be part of an
answer, especially some future putative more powerful
XProc based on sequences of XDM instances and synchronization
points - because then you need an XProc Framework...

Hi all,

Just for the sake of completeness: I hope people on this thread  
realize that there is
more to XQuery then a query language. It's also a *scripting* language.
http://www.w3.org/TR/xquery-sx-10/

The XQuery scripting extension does provide control flow capabilities  
around queries,
updates and Web function calls. It's smoothly integrated with the rest  
of  XQuery, such that it
  avoids the paradigm shift that usually costs productivity and  
performance.

(this makes XQuery a direct competitor to other scripting  
languages...Javascript, Ruby, etc..
and I think XQuery will be in the long term winning, but that's  
another story, and maybe another
email)

This is of course no excuse for not having a more sophisticated  
servlet-like framework around
XQuery/XSLT for ease of Web application building.

I believe XML needs some work in this area, hopefully standardized by  
the W3C for the
benefit of all.


Best regards
Dana

P.S. For everybody who will attending XML Prague, maybe we can have an  
evening of beer
and  discussions around this. I am looking forward to it.

In hindsight, that's too bad  :(
In most of the cases where I work with XML with namespaces, I'm generating 
in a different namespaces (or none) then I am querying.
My own experience would suggest that's the common, not the outlying case.

It's not a bug, and yes it does make you want to scream.

The nicest approach to this I have seen so far is in day's Sling
framework. Basically you have a hierarchical repository of
files/documents that have MIME types (multiple though), and if a
request hits a file, handlers are triggered on MIME type and
conditions of the request (method, headers, accept, ...). Of course
they also support rewriting and path mapping, but I find the first
approach nicer. If you have side effect free handlers (hello XQuery)
you could also get proper HTTP cache support for free.

Pointing a browser at /path/to/my/script that then does something
magic (maybe even based on sessions!) feels so 1999 PHP style.

However this requires some relatively application specific decisions
to be taken by the framework, e.g. in xDB which metadata properties
describe the MIME types.

And frankly, the last time I looked I found eXists approach of calling
into impure functions to manipulate sessions, headers, etc. relatively
ugly. It just feels very wrong to have impurity in XQuery, at least to
me.

Yes, I was sort of quoting that. One of my all time favorites ;-)

Martin

in web applications may I proffer that REST is maybe the abstraction
layer you desire, in eXist (where there is a default RESTful
interface) u also get rewriting which when combined cover most of my
needs in this 'space'.

this reminds me of a quote (which I cannot remember) that basically
says any problem can be solved with yet another layer of abstraction,
except for the problem of too many layers of abstraction.

What would they do? What purpose would they have? Of course you can
introduce any number of indirections between XProc and XQuery, but why
would you want to?

Martin

Martin,

yes, what purpose whould they have? Two purposes I can immediately think of is to organize document flow from query to query, and automated input selection for batch processing, e.g. based on document properties and selection criteria. Let me briefly expand ideas about document flow. Imagine we introduced the concept of a "document type", not in the conventional - literal - way referring to schema and DTD, but as an abstract component identified by a QName and properties; and imagine we possess a simple language for characterizing queries in terms of input and output document types (in the sense just introduced); then things can get really in motion. And note the aspect that the whole approach is very concept minded, systematically building on new kinds of components and the semantics of their properties. Practically, this can get efficient and attractive, indeed, 

With kind regards

What would they do? What purpose would they have? Of course you can
introduce any number of indirections between XProc and XQuery, but why
would you want to?

Didn't someone once say "Any problem in computer science can be solved
with another level of indirection" :)

But then according to this:

http://en.wikipedia.org/wiki/David_Wheeler_%28computer_scientist%29

...he followed it with "But that usually will create another problem."

Michael,

no doubt about the importance of XProc as an integration language above XQuery, and no doubt we need such a language which is not confined to orchestrating XQuery queries, but "application components in different languages", namely X...-components. I would position XProc two levels above XQuery, whereas an "XQuery-only integrator" would be only one level above. If we could afford only one single language above XQuery, the choice should certainly be the higher alternative, opening much larger space for integration. But remains the question: is there no need for additional integrators between the XQuery level and the XProc level? I believe that such integrators can be designed and could be useful. However, if the small-scale integration can be done in such a generic way as to deserve standardization - this is a different question. (To explore it, a first step might be to define possible advantages in general terms.) Lightweight-integration language
 between XQuery and XProc, is it possible, yes or no, is it worthwhile, yes or no?

With kind regards,
Hans-Juergen Rennau

Some of this need is satisfied by XProc. There are some who would like to
see the whole application written in XQuery and don't want to see any other
language present. But to my mind, integration is often about combining and
reusing application components written in different languages and different
technologies, and XProc meets that need admirably.

You might want to look at xmlsh which was designed to solve this problem of 
managing the efficient interactions of many xqueries (as well as may 
non-xquery XML and non-xml pieces of a larger integration),
although perhaps not in the way you express.

Can this possibly be right? After much debugging I have bolied a
really confusing bug down to this test case. The following query
prints 3097:

<html>
{
let $num := count(collection("/db/quotes")/quote)
return $num
}
</html>

and this query prints 0:

<html xmlns="http://www.w3.org/1999/xhtml">
{
let $num := count(collection("/db/quotes")/quote)
return $num
}
</html>

The only difference is the default namespace declaration. In the
documents being queried the quote elements are indeed in no namespace.
Is XQuery really supposed to be applying default namespaces to
unqualified names in path expressions? Do I report this as a bug in
the XQuery processor or do I scream at the insanity of the XQuery
working group?

Liam,

'extend standardization "beyond the query"' - that is an excellent formula, I think! As one of the reasons why the need is real I regard the challenge of data integration. I have a feeling that there is a remarkable contradiction between potential and reality. XQuery has a great potential as an integrator, what with the possibility to just *name* the resource (URI) and immediately have its structured content under your fingertips. But if the actual usage of XQuery does not yet live up to the potential, one of the reasons may be that it is difficult to set up a system of many queries to a robust whole, although the *single* queries can be written so easily and efficiently. Put differently: it makes a great difference if the focus of integration lies within a single query, or beyond.

A movement "beyond the query": how about a processing model just one level above the query level, of moderate complexity, integrating the execution of single queries, for example by assigning to them properties which would allow to automate their squencing, input provision and output delivery? The XQuery spec provides for the possibility to write library modules, but it is not possible to formulate relationships between library functions. In general, we cannot say someting "about" a function. We cannot, for example, express that a query Q has a "logical" source document D, although the actual input is not (or not only) D itself, but the result produced by some other query Q0, likewise logically - or perhaps literally - processing D. A really simple XML language might  make it clear that the command "apply Q to D" would have to be expanded by a framework into a chain: "apply Q0 to D, resulting in R; present Q to R". We do not have this level of
 abstraction which would allow for orchestrating the individual queries. The XQuery language level knows only XDM values and expressions. I wonder if just one level above the language a simple, standardized processing model might not be possible, simple enough to be attractive and really enhancing efficiency.

With kind regards,
Hans-Juergen Rennau

Hi Hans,
The FullMoon processing framework meets the criteria you have described.
See http://projects.arcs.org.au/trac/fullmoon/wiki/FullMoon
I initially developed it in 2007 for Geoscience Australia and it was taken
over and further developed by CSIRO.
It's design is fairly generic but the packaged rule sets (xquery) are
specific to processing XMI representations of ISO19136 UML models.

Dear People,

presently I am scribbling away at a little XQuery framework into which one
may plug user-supplied queries, which pulls them into a particular larger
processing model, using them as combinable building blocks. Suddenly my pen
hovers in mid-air, I raise my head and, listening to the snowflakes
rustling in the hedge, I wonder: probably some XQuery frameworks already
exist, and we XQuery developers might really profit from being aware of
them, so that, pushing the argument to its extreme, everytime we write a
query we might immediately consider plugging it into this or that
framework, to enhance its usefulness.

So my *question*: would anybody like to point to some XQuery framework into
which one may plug queries in order to harvest added value, perhaps hinting
at the kind of advantage one obtains?

With kind regards,
Hans-Juergen Rennau


PS: Before closing, one word about XProc. I would not regard the language
itself as such a framework, rather as a toolkit for creating such
frameworks, implementing them perhaps as a set of XProc documents.

As George said, the term "framework" is a bit vague.

This might be of interest, although I'm not sure it is
much used or maintained:

Xaj: Simple XQuery API for Java
http://xaj.sourceforge.net/

-- 
Michael Ludwig

Florent, James, Dennis,

cordial thanks for your facts and comments! Trying to evaluate them. let me first indeed define the term "framework" for the purpose of this discussion. Taking as a starting point an isolated XQuery module, a *framework* is a machinery enabling a more complex processing than provided by the XQuery module itself, thus controlling and in some way embedding the query execution within a larger processing model. So if we assume a query defines a processing P, the framework would provide for a composite processing, say, X-P-Y. A typical example is a web application, where the query execution is preceded by request evaluation and followed by response dispatchal..

Adopting this definition, I think that the following links relate to libraries, but not to frameworks:

http://www.expath.org
http://www.exquery.org
http://www.xqueryfunctions.com/xq/

And the servlet-like specification Florent spoke of would appear as a standard whose implementation would result in a framework.

The remaining links:
http://sausalito.28msec.com
http://code.google.com/p/xqmvc/

definitely refer to frameworks, and both are dedicated to creating web applications, in one case "in general", in the other obeying the MVC pattern. Finally, as Florent pointed out, XML database implementations usually contain such a framework, too.

This is an interesting first result: frameworks for creating web applications exist, and they are impressive, indeed! Frameworks for other purposes have not yet been mentioned.

Thank you again, with kind regards,
Hans-Juergen

You might be able to do it by simply defining a sequence containing
(references to) the relevant nodes, rather than a newly constructed tree.
But I don't think there's a simple solution you're missing.

  Just to add to responses sent by Jim and Dennis, I'd like to
say it depends what you mean by "framework".  The definition of
this term is quite vague, and even when you have one definition,
it depends on what aspects to solve you are looking for after
frameworks.

  If you are looking for a way to evaluate queries on a server in
response to an HTTP request (well known as XQuery webapps), then
Sausalito is worth investigating.  Almost all XML databases like
MarkLogic and eXist do also provide some way to plug queries into
their HTTP server.

  The drawback with this approach is that those solutions are all
dependent on the processor and/or the chosen framework.  As part
of EXPath, I'm trying to define a first version of a servlet-like
specification, that will be implementation-independent.  Its
success will depend on which extent implementors will adopt it.

  But I do not think this is really a framework.  This is more a
low-level technical piece to help developing larger frameworks in
a processor-independent way.  Sausalito for instance would be a
good example: if it was based on such a spec for its mapping
between HTTP and XQuery, it would be (for that part at least)
independent on the underlying processor.

  Any way, if you are interested by those matters, do not miss
the XML Prague 2010 conferences <http://xmlprague.cz/> :-)

u prob know about these libraries

http://www.expath.org

http://www.exquery.org

http://www.xqueryfunctions.com/xq/

and then there is

http://code.google.com/p/xqmvc/

I am also creating a generic XQuery version (for use in eXist) that
kind of emulates xqmvc ... will release at some point soon.

Dear People,

presently I am scribbling away at a little XQuery framework into which one may plug user-supplied queries, which pulls them into a particular larger processing model, using them as combinable building blocks. Suddenly my pen hovers in mid-air, I raise my head and, listening to the snowflakes rustling in the hedge, I wonder: probably some XQuery frameworks already exist, and we XQuery developers might really profit from being aware of them, so that, pushing the argument to its extreme, everytime we write a query we might immediately consider plugging it into this or that framework, to enhance its usefulness.

So my *question*: would anybody like to point to some XQuery framework into which one may plug queries in order to harvest added value, perhaps hinting at the kind of advantage one obtains?

With kind regards,
Hans-Juergen Rennau

I have a flat file that I am running thru Stylus Studio. Stylus Studio
takes the flat file and converts it to XML and then runs it thru an
xQuery.  

 

Every time I need to process this I need to open stylus studio and press
the run button.  Is there a script I can run to run the xQuery so I can
automate this process?

 

Thanks

  I didn't look in the details, but my first reaction to such a
problem would be to separate the navigation within the data on
the one hand and the formatting of them on the other hand.

  So in this case, I would first write a set of functions that
extract the correct data from the correct documents and walk
through them in the correct order.  At the place where each
subset of data has to be transformed during this navigation, you
call then a second set of functions, which handle the formatting
of a single one at a time.

  Hope that helps, regards,

Hi Mike,

In this case I have 48 years worth of transcribed historical diary,
with each day/month/year being one of the objects I want to find the
previous/next node for.  The query gets a parameter in YYYY-MM-DD,
YYYY-MM or YYYY format and returns the appropriate year, month or day
from the correct file because this parameter value makes up part of
the @xml:id.  In each instance I want to provide prevYear/nextYear,
prevMonth/nextMonth, prevDay/nextDay navigational links regardless of
the fact that I'm sitting on 1798-01-01 and the 1797-12-31 (if it
exists) is in the previous file.

One straightforward solution is of course to generate a skeleton of
the entire collection:

<collection>
<year xml:id="diary1797">
 ....
<month xml:id="diary1797-12">
...
<day xml:id="diary1797-12-31/>
</month>
</year>
<year xml:id="diary1798">
 <month xml:id="diary1798-01">
  <day xml:id="diary1798-01-01"/>
...
</month>
</year>
</collection>

and use that as a lookup table...as then preceding::day[1]  (or month
or year) from the current id's location in that file would work and
give me just what I need.  However, that seemed like a terribly kludgy
workaround. (There are only 48 years of the diary...so that would be
some 18K elements....but all this makes me think I'm missing a much
easier way!)

Since my XQuery knowledge still is at a basic level I'm happy for any
suggestions you might have.

Yes, the code you've written doesn't solve the problem, for the reasons you
have discovered.

Perhaps you could describe the problem: it's not easy to reverse-engineer it
from code that doesn't work.

Hiya,

I want to do something (fairly inefficient) like:

let $
let $elementOfInterest := collection(/db/files)//tei:*[@xml:id=$elementID]
(...)
let $previousElementID :=
data($elementOfInterest/preceding::tei:ab[@type='foo'][1]/@xml:id)
let $followingElementID :=
data($elementOfInterest/following::tei:ab[@type='foo'][1]/@xml:id)

but my problem is that preceding:: and following:: seem to stop at the
document boundary rather than the collection as a whole.  So, when I
get to the first element of any document it doesn't find the next
element as being the last one in the preceding file.

I realise I'm probably missing something simple here.

Thanks for any help,

-James

The W3C's XML Query Working Group and XSL Working Group are pleased 
to announce the availability of version 1.0.1 of the XQuery and XPath 
Full Text Test Suite (XQFTTS) at 
http://dev.w3.org/2007/xpath-full-text-10-test-suite/.  The tests 
suite contains information about how to run the test suite and how to 
submit the results (anonymously, if you desire).

XQFTTS 1.0.1 fixes a number of bugs reported against XQFTTS 1.0.0 and 
it reflects a small number of CR issues that have been resolved by 
the WGs. We encourage implementors who have sent us reports for 
XQFTTS 1.0.0 to run XQFTTS 1.0.1 and send us their final reports. 
Implementors who have not yet run the XQFTTS at all are strongly 
encouraged to run XQFTTF 1.0.1 and submit their implementation 
reports.  The reports that we have received provide a significant 
amount of the implementation experience that we need to request a 
transition to Proposed Recommendation. We would especially appreciate 
a report showing an implementation of Minimal Conformance using the 
XQueryX syntax.

We will continue to maintain and enhance the test suite after our 
transition to Proposed Recommendation. We do not expect to send out 
any further announcements about our test suite -- any news or updates 
will be posted on our web page.

Thanks!
    Jim

Hi,

A couple of weeks ago we started a wiki at http://xquery.pbworks.com
in order to help XQuery enthusiasts from the same area to gather
around a snack and a beer.
Our aim is to promote knowledge sharing and best practice amongst
XQuery developers and business professionals around the world by
organizing local meetups.

Are you interested in organizing a meetup in your area?
The wiki contains some guidelines and tips of organizing such event.
Keep it small and informal, it's actually not much work and a lot of fun :-)

Best regards,

William

In the meantime you could use a concatenation of these functions -
http://www.xqueryfunctions.com/xq/c0002.html

...Or depending on the XQuery Engine Implementation that you are
using, they may provide an extension function, eXist-db provides the
datetime: extension namespace for such functions and I believe that
MarkLogic also offer something.

"XQuery 1.1 MUST include additional library functions or an equivalent
mechanism to perform formatting of date and time values."

:) that's pretty much how I feel about it....

XQuery appears to lacking a format-date() function... for example to
get "21st Jan 2010" I would use:

format-date(xs:date('2010-01-21'), '[D1o] [MNn,*-3] [Y0001]')

Do I need to do that manually in XQuery?

In XQuery 1.1, this function does exist:

In XQuery 1.0, you do have to do it yourself.

Hello Elliotte,

you might find my article on Advanced XQuery useful

http://www.ibm.com/developerworks/edu/x-dw-x-advxquery.html

.. if u cant be bothered with IBM logon I have a pdf on my site here

How about:

let $quote :=
<blockquote cite="foo">
foo
<p>bar</p>
other random text and elements
</blockquote>
return
    <blockquote>{$quote/@*}<div>{$quote/node()}</div></blockquote>

If you need to apply several transformations like this, using a
recursive function might work best:

declare function local:filter($node as node()) {
    typeswitch ($node)
        case element(blockquote) return
            <blockquote>{$node/@*}<div>{$node/node()}</div></blockquote>
        case element() return
            element { node-name($node) } { for $child in $node/node()
return local:transform($child) }
        default return
            $node
};

there isn't xsl;copy but there is xsl:element name="{name()}" which is 
more or less the same thing.

let $s :=
<blockquote cite="foo">

stuff <br/> more
</blockquote>
return

element {node-name($s)} {$s/@*,<div>{$s/node()}</div>}

into this

<blockquote cite="foo"><div>
foo
<p>bar</p>

other random text and elements
</div>
</blockquote>

That is, I just want to add the div around the content, but preserve
everything else.

This is straight-forward in XSLT. Is it as hard in XQuery as it seems
to me? Or am I missing something obvious? What I need is an equivalent
of the xsl:copy function.

That was one reason I sugested switching to elements rather than string
sequences as (perhaps) it is more likely that they get indexed (in xslt
you could force indexing with xsl:key) but I didn't mention that as it's
not clear which processeors would index what, especially if the actual
data only has length 12.

Use an XML lookup table

<data>
  <item code="s" value="sugar"/>
  <item code="t" value="tea"/>
  ...
</data>

Saxon-EE will generally implement the lookup $data/item[@code=$c] by
building an index.

so would I probably, but it wouldn't look as interesting in a mailing

yes definitely: that was probably the main point of my reply (but perhaps
obsured by the coding style I chose:-) that in xquery you can use xml
structure to  make more interesting mapping structures, you are not
restricted to integer indexed indexing into lists of strings.

David

The solutions we've seen have all more than likely been linear searches 
(an implementation could do better but I think it's unlikely). Using 
either XML structure (for string based keys/values), or the closure 
facilities of higher order functions (XQuery 1.1 WD, works with keys / 
values of any type), it is also possible to build binary search trees 
like a red/black tree. I don't know of any publicly available XQuery 
modules which implement that yet, but I've written one myself that uses 
XQuery 1.1 higher order functions.

index-of(...) would still be a valid solution as it can operate on a
sequence of any atomic type, not just strings -

Others have suggested strings and index-of. An alternative, more
xml-oriented, version  would be

<x><January/><February/><March/><April/>...</x>/February/count(preceding-sibling::*)+1


or to avoid the possibly linear sibling count, 

<x><January n="1"/><February n="2"/><March n="3"/><April n="4"/>...</x>/February/number(@n)

This solution gets a little more tedious if the month name comes as data 
instead of hard-coded in the xquery.
E,g you have to do something like

    let $months := <x><Janurary/> ... </x>,
         $month := "March" (: or some extracted value :)
   return  $months/*[node-name(.) eq $month]/count(preceding-sibling::*)+1

This is why I wouldn't put key values as element names.  It also limits you 
to valid element names.
I would use attributes or values as key values.

When I start getting complicated maps I generate a xml structure like this
<map>
   <entry key="key">Value</entry>
...
</map>

This gives you atomic types for keys and (almost) any xdm value value for 
the value.


Having keys be non-strings or numbers gets a bit trickier and difficult to 
generalize.
You have to start defining what equality is in something like
     <entry>
       <key><node>key value</node></key>
       <value><node>value</node></value>
    </entry>


Defining equality for <node> is generally not a generically answerable 
question.
Whereas using atomic values for keys is comparable universally with "eq"

These all look good. What if we generalize the problem? Given an
ordered list of N values (not necessarily strings) map each one to
another value (not necessarily a number).

I suppose you could use two elements. E.g.

<keys><January/><February/><March/><April/>...</keys>
<values><foo/><bar/><baz/><foo/>...</values>

Then use the position of the key to select the right value.

oXygen does not enable the XQuery 1.1 support of Saxon EE. We will add 
this as an option in the next release, in a couple of months.

i just want to learn about new XQuery 1.1 features - i got this
message from trial version of OxygenXML but did not find something for
XQuery 1.1 in Options...

BTW i start to learn XSLT 1.0 from draft too in previous millenium -
do you remenber "sort" in draft was as attribute (not as xsl:sort
element)? ;)

so i think it ok if something will change - i am metaprogramming fan
so syntax changes not problem at all for me

for me main problem when nothing changes - at this "stalled" time i
think about death as "act of creation"

for now i have not money nor for OxygenXML nor for SaxonEE - what
about possibility to get license "on trust"?

Oxygen enables Saxon-EE features, so you should be able to use this.

I haven't actually got the latest version of Oxygen installed, so I can't
point you to the right buttons to press. I suggest you ask them for advice.
They are always very ready to help.

It does help to say what you are doing when you raise a question on a forum.
If you had said you were using Oxygen, we could have wasted less time.

Indeed, the reason that Saxon makes you jump through several hoops before
you can use XQuery 1.1 features is to ensure that you don't do it without
thinking twice about it: the specification may change, the product may
change, and your queries may stop working.

Saxon questions are best asked on the saxon-help list.

And with any question, it's best to say what you were trying to achieve, and
what you did, and how it failed.

The error message means that your query does something that's allowed in
XQuery 1.1 but not in 1.0, but you didn't say you wanted to use XQuery 1.1.
You need to have version 1.1 specified in the version declaration in the
query prolog, and to request XQuery 1.1 processing on the command line or
via the API.

sacrificed five pigeons and called Saxon! in a loud
voice, and the XQuery 1.1 specification did not suddenly
get published as a W3C Recommendation as a result?

To be less flippant, XQuery 1.1 does not yet exists -- there is
a draft, but no actual final language.  Saxon PE 9.2, acording
to Mike Kay's web page [1] does have some XQuery 1.1 features,
and if you are using those you need to check your support contract
(since Saxon PE is a commercial product).

Hello XQuery lovers!

The first Zurich XQuery Meetup will be held in a prestigious location
in the heart of the city, ETH Dozentenfoyer, March 11th 2010. More
details at http://xquery.pbworks.com/Zurich-Meetup.
Registration is done on the wiki.
The meetup is just before XML Prague (March 13th and 14th) so feel
free to stop by Zurich if you are on your way to Prague ;-)

Best regards,

William

In this case I would like to create a new element of that type, ie, one that is not read from the input file, so I guess the validation is required. 

Thank you for the reply.

The validate{} expression will take untyped data, validate it against the
schema, and return typed data.

If your data has already been validated, you don't need to do this, you only
need to declare its type. Typically this is done using the "as" clause. For
example

let $invoice as schema-element(my:invoice) := doc('invoice.xml')/*
return ...

This will fail if doc() doesn't do the validation; how you control whether
or not doc() does validation is processor-specific, and will often involve
some kind of configuration options. In Saxon, for example, when you set
-val:strict on the command line, all input documents will be validated. (In
Altova, I believe validation happens if and only if there is an
xsi:schemaLocation attribute within the document itself.)

Hello all, 

I'm trying to declare a variable to be of a type that is imported from an XML schema definition. 

So far what I've been doing is something like:

let $var := validate { element {$type} { $value } } ...

and it works although is a bit cumbersome. 
Is there an easier way to do this, ie, without using the validate {} ?

Thanks,

Hi Martin,

Thank you very much for the help. The solution worked.

[Also, $tagname was redundant, as you pointed out.]

Thank you,

I'm not quite sure what you are trying to achieve here, but
//foo//$bar does certainly not work. If you want to look for elements
that have a name which you don't know statically (i.e. it's in a
variable), you should write:

let $searchtag := $search-for/location_in_TM
let $tags := //production//*[name(.) = $searchtag] (: or node-name(.)
if you use namespaces :)

Basically you use a predicate on any node, and within that you check
for the name of the current context node (name(.)) to equal whatever
you are looking for. You can also compare against multiple names (i.e.
$searchtags) at the same time, that might help with performance.

I'm guessing what you want is

for $element in //*[name(.) = $searchtag]

I don't quite understand what you are trying to achieve with $tagname,
this appears redundant.

Martin

Hello,

I would appreciate any help with the following problem.

Situation: An XML document may contain any number of boilerplates dependent
on various factors. These boilerplates will be located within certain
elements, depending on the type of boilerplate being used. Often, if said
element is used, it must have a certain boilerplate associated with it.

Goal: To create a report for technical writers that will search their XML
and report to them which boilerplates are missing.

Methodology: In an attempt to avoid hard coding each situation, the idea is
to pull in information from one document and use it to determine which
elements to search in the other document.

Here is the relevant section of the file [list.gent] containing the
information that will be used to search the other file
************************************************
<list>
  <required_boilerplates>
	<boilerplate>
		<name>warranty information</name>
		<location_in_TM>wrntyref</location_in_TM>
		<string_search>The warranty starts on the date found in
block 23 of DA Form 2408-9, Equipment Control Record.</string_search>
	
<location_of_bp>C:\svn_sdi_skeleton_creator\BOILERPLATES\GIM\ginfowp\warrant
y_ information.gent</location_of_bp>
		<reason>Required by Standard</reason>
	</boilerplate>
  </required_boilerplates>
</list>
************************************************

The relevant section of the xquery is as follows. An explanation will
follow. Note: $production in //production does not require a doc function as
it pulls in the correct document from a java program. [Or rather the java
program pulls in the xquery and supplies the document for it.]
************************************************
<h3>Required boilerplates</h3>
		<p>The following boilerplates are required, but are
missing.</p>
		<table border = "1">
			<tr>
				<td>boilerplate name</td>
				<td>reason</td>
				<td>location</td>
				<td>wpno</td>
				<td>xpath</td>
				
			</tr>
{
		for $production in //production,
			$search-for in doc("list.gent")//boilerplate
			
		let $searchtag := $search-for/location_in_TM
		let $tagname := //production//$searchtag
			
		return(
		
		for $elementsearch in //$tagname
		
		where not(contains(data($elementsearch),
data($search-for/string_search)))
		 
		return  
					<tr>{
	
<td>{$search-for/location_in_TM}</td>, (:don't forget comma or error result
:)
	
<td>{data($search-for/reason)}</td>,
	
<td>{data($search-for/location_of_bp)}</td>,
	
<td>{data($elementsearch/ancestor::*/@wpno)}</td>,
	
<td>{$elementsearch/string-join(ancestor-or-self::* /f:name-and-position(.),
'/')}</td>
					}</tr>
		
 
)

}
		</table>
************************************************

Explanation: I apologize if anything above is a bit of a mess. I'm still new
to xquery and probably not writing the code in the most efficient method.

1. for $production in //production,
			$search-for in doc("list.gent")//boilerplate
This section is meant to search through both documents. The writer's xml
itself is too large to include here. I believe the only relevant information
is that production is the root element. From the list.gent "wrntyref" is the
element that will be searched for in the XML. Wrntyref is an optional
descendant of production. It has a set xpath from production, but that xpath
is irrelevant as the goal is to use any element taken from
list/location_in_TM and process it against the XML being used by the
writers.

2. let $searchtag := $search-for/location_in_TM is to get the value from
location_in_TM from list.gent and place it in a variable.

3. let $tagname := //production//$searchtag is my attempt to create an xpath
using the root of the writer's xml and the variable $searchtag.

4. The second FWR within the first Return was the only way I could guess to
process each occurrence of the value taken in location_in_TM [and stored in
$searchtag] and process it for each occurrence in the writer's xml.

****

Result: The following output was achieved.
************************************************
boilerplate name 	reason 			location

wrntyref  		Required by Standard
C:\svn_sdi_skeleton_creator\BOILERPLATES\GIM\ginfowp\warranty_
information.gent 
[following is a continuation of first line]
wpno 		xpath
	
list[1]/required_boilerplates[1]/boilerplate[1]/location_in_TM[1]
************************************************
The xpath is derived from the following function

declare function f:name-and-position($n as element()) as xs:string {
  concat(name($n), '[', 1+count($n/preceding-sibling::*[node-name(.) =
node-name($n)]), ']')
};

The function works correctly as proven in use elsewhere, but the xpath shown
is incorrect. It is pointing to the list.gent file instead of the writer's
XML. Since $elementsearch is also used in the where statement, this means
the same problem is also occurring there.

****

Questions:
1. How do I write the xquery so that $elementsearch is pointing to the
correct [the writer's] XML?
2. Is there a better method I should be looking at instead?

Thanks for your time and help.

Thank you,
 
Kenneth Dougherty

Hi Ken,
Thanks a lot for your reply. I think your approach and code might help me in
implementing the same for my requirement which is somewhat complex than the
sample i had explained in the mail.

Back in August, the XML Query Working Group announced the availability of 
version 1.0.0 of the XQuery Update Facility Test Suite [1]. This test 
suite reflects the XQuery Update Facility 1.0 Candidate Recommendation [2] 
that was published on June 9. 

We are pleased to have received results for BaseX, MXQuery, Saxon-EE, xDB, 
and Zorba [3]. We are still looking for implementations that support the 
Update Facility Static Typing Feature and implementations that support 
XQueryX. We'd like to encourage implementors of these features to submit 
their results to us, so that we can advance XQuery Update Facility to W3C 
Recommendation.

Dear All,

I am doing transformation xml to xml using xquery. Here find the below
my xml, ouput and xqy file. I have tried but i could not find how i
will delete <page> and create ID attribute as it as a same content.
(eg. Forward for forward, content for conent).

XML
====
<p><entry><text>Foreword<page>v</page></text><author>Fen</author></entry></p>

Output
=====

<para id="foreword">Foreword</para>

my xqy
======

let $ad := doc("file:///d:/Byomokesh/PubXML/xquery/sample.xml")
let $ad2 := $ad//text
for $r  in $ad2
return
<s>{data($r)}</s>


Thanks
Byomokesh

Ah, I see. Simplest solution is

let $ad := doc("file:///d:/Byomokesh/PubXML/xquery/sample.xml")
for $r in $ad//text
return <para id="{lower-case($r/text())}">{$r/text()}</para>

but that's not very robust if there's extra whitespace or comments in the
source: slightly safer is to replace $r/text() in both places by
string-join($r/text(), '') to allow for the possibility of multiple text
nodes.

Perhaps you want something like

let $ad := doc("file:///d:/Byomokesh/PubXML/xquery/sample.xml")
for $r in $ad//text
return <para id="{lower-case($r)}">{data($r)}</para>

Dear all,

we are glad to announce the release of BaseX 6.0. It offers a bunch of
new features, such as:

- a full implementation of XQuery Update, reaching 100% in the W3C Test Suite.
- an enhanced client/server architecture with ACID-safe transactions,
user and password management and transaction logging.
- extended XQuery Full Text features, supporting TF/IDF scoring, stop
word lists, fuzzy querying, etc.
- the improved creation of index structures, using constant memory.
- optimizations to increase the use of index structures and iterative
query processing.

BaseX is open-source. It is developed by the DBIS Group at University
of Konstanz. Please find more information at http://basex.org/

All the best,

Christian Grün
BaseX Team

Hi,

Sorry. It was typo error. I want transform from one xml to another xml

(Look the <navpoint> Tag and <Content..>
3. <Content Tag.

Its very had to write. Please look deeply my input and output.

Thanks
Byomokesh

Your input has

1 Room for Manoeuvre

and you want the output to be

1 Room for Manoeuvre and the Paradox of Globalization

That could be tricky.

Apart from that kind of detail, which I'm sure is just carelessness in your
posting, it's hard to see exactly what your problem is. If you explain why
you are finding this difficult, then it might be easier to help you.

There are plenty of ways of changing the way Saxon reports error messages -
if you want help on this, please use the Saxon help list.  However, there is
no way of avoiding the error: if your input is not well-formed XML, Saxon

Hi,

This is a now problem, some xml read have this problem and I convert the xml
to uft-8. I would like to avoid this message (SXXP0003 ...) at the console,
because I read a many files. Is possible set any parameter at saxon to avoid
the error message at the console?

You usually get that when you parse latin1 or cp1252 (or other) as UTF8.

Either:

a) correct the encoding in the xml prolog (or add a prolog with the
correct encoding)

or

b) convert the XML to UTF-8.  (you could do that using a tool like
Notepad++)

Hi Jesus,

Messages like these are typically observed when your parser thinks it is receiving a UTF-8 encoded document, while it is actually something else. Does your xml contain an XML declaration containing the correct encoding? Or are you setting the wrong encoding programmatically perhaps?

Kind regards,
Geert

ok, first one is very good question. I didn't think about it. Thanks for
your observation.
For the time being we will leave it.

Let's come to your second question, if designators are alpha-numeric then
change in format may be like only numeric or only alpha.

Your third question: designators in sequence means a,b,c .. or A,B,C.. or
1,2,3.. etc.

Hi All,
Wish you all a very happy and prosperous new year 2010.

I nee your help regarding following issue:

I have an xml of the form
<doc>
      <p>(a)- first level </p>
    <p>(1)- second level</p>
    <p>(2)- second level</p>
    <p>(A)- third level</p>
    <p>(B)- third level</p>
    <p>(3)- second level</p>
    <p>(b)- first level</p>
</doc>

A change in the designator(Designators may be in alpha, numeric, roman,
alpha-numeric,
etc bounded or unbounded by brackets) format must be used as basis for
identifying the primary level.
Designators in sequence or series must be treated as primary level text of
the same level. For example:
(a)-first level
(b)-first level
(c)-first level

I have to create the following output xml out of the above input xml:

<doc>
      <parent>
       <title>(a)- first level </title>
       <child><title>(1)- second level</title></child>
       <child>
        <title>(2)- second level</title>
        <child><title>(A)- third level</title></child>
        <child><title>(B)- third level</title></child>
       </child>
      <child><title>(3)- second level</title></child>
    </parent>
    <parent><title>(b)- first level</title></parent>

</doc>

Pleae advise, how to do this?
Thanks in advance.

It's not going to be easy and I'm not going to try and write the code for
you, but here's an approach.
 
You need to do a recursive walk through the siblings. On each step, pass the
current "full hierarchic section number" as a sequence, for example ("a",
"2", "B"). If the "designator" of the next element is the successor of the
last item in this sequence, or if it is the start of a new (nested)
sequence, then you can construct the next section number and continue the
recursion. If the next designator is the successor of an item in the
hierarchic section number other than the last, then you can exit one level
of recursion and try again.

I've implemented this so you can use regular expressions to determine 
the level indications.

You don't share with us what you have tried and what has not worked for you.

I have a complete solution below.  I found it easier to think first 
in XSLT because of the grouping facilities that are available, and 
then to just transliterate that into XQuery for a pure-XQuery solution.

Note that readers may find it interesting to have to do the following 
in XQuery:

   (<tree>{elements-expression}</tree>)/*

... in order to create a sibling relationship between a copy of nodes 
so that the recursive use of the following-sibling axis would not 
access the original nodes.  Simply referencing the nodes isn't 
sufficient because the nodes retain their original location in the 
original tree.

I hope this helps.

Hm. Consider the input:
   <doc>
     <p>(a)- ..</p>
     <p>(b)- ..</p>
     <p>(c)- ..</p>
     <p>(d)- ..</p>

     <p>(g)- ..</p>
     <p>(h)- ..</p>
     <p>(i)- ..</p>
   </doc>
In the last <p>, how are you supposed to know whether the "i" is alpha 
(and thus first level) or roman (and thus second level)?

And when designators are alpha-numeric, what constitutes a "change in 
format"? (What defines "designators in sequence"?)

Pavel,

I think this is something that the XQuery Working Group needs to 
consider fixing in the next revision of XQuery 1.1. Please can you raise 
this as a bug against the specification on the W3C bugzilla, to make 
sure the working groups attention is directed to it.

I have created bug 8662:

http://www.w3.org/Bugs/Public/show_bug.cgi?id=8662


As a side note, I'm personally leaning towards preferring a special
syntax for function to call itself - it just feels like this is what
I'd be using 99% of all time, and for that other 1% there's always the
hack of passing mutual recursive functions as item() arguments to each
other. Rather than having a magic variable name like $this, however, I
would propose having a magic function - I called it "recurse" in bug
description as I couldn't think of anything better, but perhaps
"iterate" or something similar might be more appropriate. The gist is
this:

1) It is only in-scope within function bodies (inline or no).
Referencing it elsewhere is a _static_ error.
2) Where available, it looks like a plain global function in the usual
namespace (http://www.w3.org/2005/xpath-functions). This means that it
can be called with the usual syntax, but also turned into a function
item using #.
3) Where available, parameter types and return type exactly match
those of the function to which the innermost enclosing body belongs
(inline or no). Again, arity mismatch in a call is a _static_ error
(as it is for any normal function).

So, the original example would look as follows with this syntax:

    function($n as xs:integer) as xs:integer {
        if ($n < 3) then 1 else recurse($n-1) + recurse($n-2)
    }(10)


Thoughts?

whether the reasoning is good or bad it essentially mirrors the
reasoning on attribute value templates in xslt (which is the model for
the {..} syntax for expressions in element content anyway, one would
guess).

in xslt 2
<a x="(:xxxx:)"/>
has an attribute with value (:xxxx:)

<a x="{(),(:xxxx:)}"/>
has an attribute with value an empty string.

Everything within curly braces is parsed as XQuery code, everything not in
curly braces is literal text. So if you want a comment, put it within curly
braces. However, {(: comment :)} is not valid, because the thing within the
curly braces must be an expression. It would have to be {(: comment :)()}.

Thanks Ken.  Do you know if this a quirk of the language or is there a
good reason for it?

Hi,

This xquery:

<body>
  (: comment one :)
  <p>
  {
    (: comment two :)
    1 to 10
  }
  </p>
</body>

produces this result:

<body>
  (: comment one :)
  <p>1 2 3 4 5 6 7 8 9 10</p>
</body>

The fact that the first comment appears in the output seems odd to
me... is that meant to happen, and if so what is the correct way to
put a comment there?

thanks
andrew

I wouldn't call it a "quirk" because it simply falls out of the syntax.

You want a comment, and in XQuery you cannot use <!-- --> because 
that constructs a comment node.  So you have to have it in an 
expression.  So that leads you to using the brace brackets for 
evaluating an expression, in which you place the comment.  But, the 
comment is removed from the expression evaluation and all that is 
left is the expression to be evaluated, which cannot be the empty string.

So it all makes sense, and I think it is reasonable.  It is just that 
it doesn't come immediately to mind, which is why it is explicitly 
part of my lecture.

I hope this helps.

I actually bring this up explicitly in my class:

   {() (: comment one :)}

The comment has to be in an expression evaluation, and the expression 
cannot be the empty string, so when I want to do what you need I use 
the empty sequence expression.

I hope this helps.

Hi,

The Error message I am getting is
 XPTY0004: A sequence of more than one item is not allowed as the first
argument of
  compare() ("", "", ...) 
 
Thank you. That tells us exactly what is wrong: there is more than one
$s/loc element, and you can't compare them all at once. However, you haven't
made it clear what output you want, for example in the case where one <loc>
element satisfies the condition and other <loc> elements do not. I can't
tell you how to correct your code because you haven't explained the
requirements clearly.
 
You could replace compare($s/loc[EXP], translate(...))=0 by
$s/loc[EXP]=translate(...) -- that would test whether ANY of the $s/loc
elements satisfies the condition. But I don't know if that's the right logic
for you.

I am trying to take element name from first file and translating ":" into

If the comparison is equal , I want all the <loc> elements.

This is xquery code:

as promised, here is a more official followup from the University
about speakers presentations and published papers.

* In Czech law copyright is always implicit and remains with the
original author, unless an explicit agreement (Copyright Transfer
Agreement) is signed by the Author. The copyright symbol has no real
meaning in legal terms so it being attached or not means naught.

* as for licensing, If there is no written agreement about license
terms in Czech, authors are always giving non-exclusive rights to
publishers as default setting.

* In last years proceedings you will see the following copyrights asserted

Copyright (c) 2009 Jiří Kosek, Vít Janota
Copyright (c) 2009 MATFYZPRESS, vydavatelství Matematicko-fyzikální fakulty

Copyright of individual articles remains in hands of original authors.

MATFYZPRESS retains copyright only on the cover pages, whilst Mr.
Kosek and Mr. Janota retain copyright on the design and
ordering/layout of the articles. Once again, by czech law, the
copyright symbols themselves mean nothing and all rights would get
asserted based on authorship or separate signed agreements.

hope that clears up any misunderstandings.

regards, Jim Fuller

Hello,

I want to take substring from the value of attribute and compare it with
other string.Here is the sample xml files and sample xquery code.

I am trying to take element name from first file and translating ":" into

of attribute affter "#" and compare with element name from first file.
If the comparison is equal , I want all the <loc> elements.

This is xquery code:

return
if(compare($s/loc[substring-after(@xlink:href,'#')],translate(name($x),':','_'))=0)
then $s/loc
else count($s/loc)
  T*his query is giving error. Please suggest how can i do this.
Thanks

Sweta.

Hey, we all enjoy doing puzzles over the holiday. But puzzles are more fun
when you give people clues. Just to make it a bit easier, could you tell us

as promised, here is a more official followup from the University
about speakers presentations and published papers.

* In Czech law copyright is always implicit and remains with the
original author, unless an explicit agreement (Copyright Transfer
Agreement) is signed by the Author. The copyright symbol has no real
meaning in legal terms so it being attached or not means naught.

* as for licensing, If there is no written agreement about license
terms in Czech, authors are always giving non-exclusive rights to
publishers as default setting.

* In last years proceedings you will see the following copyrights asserted

Copyright (c) 2009 Jiří Kosek, Vít Janota
Copyright (c) 2009 MATFYZPRESS, vydavatelství Matematicko-fyzikální fakulty

Copyright of individual articles remains in hands of original authors.

MATFYZPRESS retains copyright only on the cover pages, whilst Mr.
Kosek and Mr. Janota retain copyright on the design and
ordering/layout of the articles. Once again, by czech law, the
copyright symbols themselves mean nothing and all rights would get
asserted based on authorship or separate signed agreements.

hope that clears up any misunderstandings.

This is what you are asking for:

   substring-after(@xlink:href,'#') eq translate(name($x),':','_')]

It would really help volunteers to know what the problem is you are 
having.  And to give XML fragments volunteers can use that will work 
with your query.  For example, your query has a reference to an 
element named linkbase which is not in the XML.

But I've tried to recreate your example below ... I hope this helps.

as promised, here is a more official followup from the University
about speakers presentations and published papers.

* In Czech law copyright is always implicit and remains with the
original author, unless an explicit agreement (Copyright Transfer
Agreement) is signed by the Author. The copyright symbol has no real
meaning in legal terms so it being attached or not means naught.

* as for licensing, If there is no written agreement about license
terms in Czech, authors are always giving non-exclusive rights to
publishers as default setting.

* In last years proceedings you will see the following copyrights asserted

Copyright (c) 2009 Jiří Kosek, Vít Janota
Copyright (c) 2009 MATFYZPRESS, vydavatelství Matematicko-fyzikální fakulty

Copyright of individual articles remains in hands of original authors.

MATFYZPRESS retains copyright only on the cover pages, whilst Mr.
Kosek and Mr. Janota retain copyright on the design and
ordering/layout of the articles. Once again, by czech law, the
copyright symbols themselves mean nothing and all rights would get
asserted based on authorship or separate signed agreements.

hope that clears up any misunderstandings.

let me try to be clear and respond in an official capacity.

the answer to this is a) ... with all the usual caveats (e.g. that the
pub does not invalidate someone else's copyright, which is the Authors
responsibility).

its a)

XML Prague is affiliated with Charles University/ITI and takes such
questions seriously so I will also get an official statement repeating
what I have said directly from the University (and the press that
publishes the proceedings) to confirm and amend the website
accordingly.

Previous proceedings were less clear then they could have been, thank
you for pointing this out and know that next years will be crystal
clear on this point.

Hi Jens,

as an alternative to using XSLT or XQuery Update, my standard XQuery
solution would be to create a recursive filter function with a
typeswitch statement. Tested with saxon:

declare namespace dc="http://purl.org/dc/elements/1.1/";

declare variable $xml :=
    <object id="O33051">
        <view id="V33052">
            <original filename="374.jpg"
hash="a72ff5300a4e5cba7c6d58d581f7c220"/>
            <img height="141" src="img/V33052.original" use="pict" width="213"/>
            <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
                 xmlns:dc="http://purl.org/dc/elements/1.1/">
                <rdf:Description

rdf:about="petal://kjc-fs2.kjc.uni-heidelberg.de:8081/HIEditor_2.0-Service/P67/V33052"

                </rdf:Description>
            </rdf:RDF>
        </view>
    </object>;

declare function local:modify($title as element(dc:title)) {
    <dc:title xml:lang="xx">{$title/text()}</dc:title>
};

declare function local:filter($node as node()) {
    typeswitch ($node)
        case element(dc:title) return
            ($node, local:modify($node))
        case element() return
            element { node-name($node) } { $node/@*, for $child in
$node/node() return local:filter($child) }
        default return
            $node

local:filter($xml)

Hello! I am an xquery newbie - please bear over with me (for a while, at least)!

Some of the elements in my file I want to duplicate in order to make some character substitutions in the duplicate (the original element contents uses diacritica and in the duplicated one the diacritica is dissolved). I can easily extract the elements and convert their contents, but how do I insert into the parent element? There are functions for adding and deleting attributes and one can "except" an element, but how does one add one?

What I have is something like this:

<object id="O33051">
        <view id="V33052">
            <original filename="374.jpg" hash="a72ff5300a4e5cba7c6d58d581f7c220"/>
            <img height="141" src="img/V33052.original" use="pict" width="213"/>
            <rdf:RDF>
                <rdf:Description
                    rdf:about="petal://kjc-fs2.kjc.uni-heidelberg.de:8081/HIEditor_2.0-Service/P67/V33052"
                    xml:lang="en">
                    <dc:title>daṃtahastavināyaka</dc:title>
                    <dc:source/>
                    <HIBase:annotation/>
                </rdf:Description>
            </rdf:RDF>
        </view>
    </object>

and I want to get something like this (note the two <dc:title>, the added one with an extra attribute):

<object id="O33051">
        <view id="V33052">
            <original filename="374.jpg" hash="a72ff5300a4e5cba7c6d58d581f7c220"/>

                    xml:lang="en">
                    <dc:title>daṃtahastavināyaka</dc:title>
                    <dc:title xml:lang="xx">damtahastavinayaka</dc:title>
                    <dc:source/>

                </rdf:Description>
            </rdf:RDF>
        </view>
</object>

but all I manage to get is something like this:

<object id="O33051">
        <view id="V33052">
            <original filename="374.jpg" hash="a72ff5300a4e5cba7c6d58d581f7c220"/>

Does my question make sense? And is there a way to do this?

The files are from the XML output of HyperImage <http://www.uni-lueneburg.de/hyperimage/hyperimage/>.

Transformations that involve making a small change to an existing document are best handled either with XSLT, or using XQuery Update. It can be done in XQuery, but it's a lot of work in comparison with the other approaches. So the first thing is to establish whether this really has to be an XQuery solution.

James, Michael,

thanks for your answers.

I think my question wasn't clear.

XML Prague has to take a clear decision about the status of the papers:
(a) are they part of an informal proceedings (in which case they can  
be submitted
somewhere else without infringing any copyright and affecting prior  
publication
status), or (b)  they are part of a copyrighted publication (in which  
case they cannot).

The Web site doesn't say either way, and that causes problems.
[[ I understand from James's answer that (a) is what is meant to be,  
but it's not clear...]]
[[ and unfortunately, being published "on the Web" can be interpreted  
either way...]]

For example, if a student submits a research proposal to XML Prague,  
and sends it
  in the same time to a copyrighted publication (like Sigmod), then  
Sigmod had serious
grounds for rejecting the submission because of the lack of clarity of  
the XML Prague
web site about this issue.

The students I am working with are worried about this.  Copyrights are  
serious business
in their world.

Thanks, best regards
Dana

Having attended and spoken at several past events, but not being in any way
involved in the organisation, I would say: concentrate on saying something
that is going to be interesting to the audience, and not commercial; don't
worry too much about the academic criteria of originality or full citations
of previous related work. For example, if you were to talk on scripting in
XQuery, present the current state of play, not the delta changes that have
occurred in the three months since your last paper on the subject. No-one
except other researchers in your own field wants to hear that kind of paper,
and this is not primarily a conference where you are addressing other
researchers in your own field.

It is (or has been in the past) a single-stream conference, which means your
audience is less specialized. This also means that because everyone is
present at the same talks, speakers get a lot of opportunity to relate their
work to other things that have been discussed in the conference, which makes
it a more interactive experience.

If foo and bar are sufficiently related to be alternative results of the
function, then perhaps they should be members of a substitution group, in
which case you can say $root as schema-element(s) where s is the name of the
substitution group.

This becomes easier in XSD 1.1 where elements can belong to more than one
substitution group.

  Yes, that would be interesting, but that's not possible.  See the production SequenceType in the spec.

Well that's not very bizarre, eventually you would arrive at the Y

No: the inner (recursive) calls to fib() would fail saying the function is
undefined. Anonymous functions can't be recursive because there is no way
they can refer to themselves.

James,

the conference web site says very little (close to nothing) about the  
fate of the submissions,
which makes it difficult to contribute to.

For example, how are the papers considered: are they considered  
publications ?
are double submissions accepted ? can they resubmit their results  
somewhere else after that ?

It would be important to know the answer to such questions, especially  
for students
and their research contributions.

Thanks, best regards
Dana

It is possible to have the function return them, but you can't 
constrain the function to validate that they are being returned.

Sequence types are used as the constraints for function declarations, 
and the following is not a sequence type:

   element(foo|bar)*

A sequence type is a combination of a data type and a 
cardinality.  So each of these are sequence types:

   element(foo)*

and

   element(bar)*

But you cannot combine the two and still have a sequence type.

I think if you had a schema aware process and you created a 
user-defined type that unions the foo and bar elements, then you 
could create a sequence type of your user-defined type ... but I 
haven't got the time today to test that.

I hope this helps.

Can't this already be done with inline functions?

This would actually be an interesting approach to this, as it would
eliminate the need to bind a function to a variable altogether (since
we really just want to call it right away, and the binding is only
there to recurse on it). This doesn't handle mutually recursive
functions, though, but then that is a much bigger issue, as it would
effectively require some way to define a group of "let" or "local
function" bindings that can all see each other, like OCaml "let rec
... and ... and ..." syntax.

I've mentioned this in my initial post. It works, but I don't like the
lack of type annotation on $func (and there's no way to express the
type of a function taking itself as an argument).

I can send you a patch, if you are willing to build MXQuery from source

Does this offer a significant advantage over using a named global function
when recursion is required? Is the advantage great enough to justify what
appears to be significant extra complexity?

If one did want to provide such a thing, I would have thought it could be
done using local function declarations: named functions declared locally
rather than globally, e.g.

       local function fib ($n as xs:integer) as xs:integer {
          if ($n < 3) then 1 else fib($n-1) + fib($n+2)
       }
       return fib(10)

and if you want it in a variable, it's 

       let $fib := fib#1

That is a tough decision in my opinion. For example, the standard
mandates that "5div 3" must be treated as an error, at least that's
the way I read it. Our parser actually contains several special case
statements that check for such conditions - normally, we'd be able to
properly parse that (and I don't quite understand why it should be a
problem), but we need special logic to prevent that. The same thing
applies to casting strings to QNames at run time, and other similar
things. I'm actually thinking about implementing a more rigid
standards compliancy mode that enforces these things, and a more
lenient mode. Preventing things like the run time case to QName is
quite a pain for users, and it's entirely gratuitous in my opinion.

Yes, I've generally gone out of my way to implement and enforce such rules.
But I also tried to get the WG to agree to tighter wording on conformance to
disallow syntactic extensions, and they pushed back.

> (and I don't quite understand why it should be a problem),

If I remember, it was a rather silly discussion of why 5e0 should be
tokenized differently from 5else0, leading to the rule in 2.2 that adjacent
non-delimiting termial symbols must be separated by whitespace.

Again there's a history, but the final result ended up slightly absurd,
given that there are other constructs in XQuery (element constructors) where
the static namespace context needs to be known at run-time. The original
rule was to ensure that casting QName to string didn't need to know the
static namespace context (because the system would then have to keep this
context for all casts, just in case the operand turns out to be a QName);
the current rule was introduced for symmetry, and somehow got left in when
the QName->string case was resolved by making QNames into triples.

Well, personally, I treat the word "support" in specifications as poison.
What does it mean? We read of applications that "support" Linux, of products
that "support" standards (say XQuery), and here of a language that
"supports" a particular feature. Almost invariably, and certainly here, it's
a bad choice of verb.

It's fairly clear that this sentence means that a minimally conformant
XQuery implementation will reject use of the namespace axis, and provides no
mechanism for getting access to namespace nodes. But it doesn't say that an
implementation is non-conformant if it does provide those features. The
specification explicitly doesn't say that a conforming implementation must
reject any construct that isn't defined in (or "supported by") the spec: and
as far as I have been able to determine, that is a deliberate omission. The
cultural background of XQuery is in the database world, where vendors
routinely expect to implement their own enhancements to standards and users
typically don't complain.

I would say it is not bothering anybody when there happens to be some implementation that supports it, for some kind of backwards compatibility reason perhaps.

But if it is mentioned that explicitly, its use should not be advocated. I will refrain from it, though I have to say that it made solving my problem quite easy.. :-/

The XQuery working Group has just published new versions of the 
following specifications:

XQuery 1.1: An XML Query Language
http://www.w3.org/TR/2009/WD-xquery-11-20091215/

XQueryX 1.1
http://www.w3.org/TR/2009/WD-xqueryx-11-20091215/

XQuery 1.1 Requirements
http://www.w3.org/TR/2009/WD-xquery-11-requirements-20091215/

These include a number of significant new XQuery features, including:

* group by clause in FLWOR Expressions
* tumbling window and sliding window in FLWOR Expressions
* count clause in FLWOR Expressions
* allowing empty in 3.8.2 For Clause (for functionality similar to
   outer joins in SQL)
* try/catch expressions
* Dynamic function invocation
* Inline functions
* Private functions
* Nondeterministic functions
* Switch expressions
* Computed namespace constructors
* Output declarations

The XQuery and XSL Working Groups have published First Public Working 
Drafts of the following specifications:

XPath 2.1
http://www.w3.org/TR/2009/WD-xpath-21-20091215/

XQuery and XPath Data Model 1.1
http://www.w3.org/TR/2009/WD-xpath-datamodel-11-20091215/

I believe so. In a pure language like XQuery, recursion has to be used
in any place where an imperative language would use a loop where every
next iteration depends on results computed by a previous iteration.
The problem with using global function definitions for that purpose is
that they 1) pollute the namespace, and 2) don't capture the local
environment. In practice, #2 is probably the biggest deal. I'm not
talking about reusable recursive functions here, but basically
something that would be written only to be immediately called
somewhere inside another function, where I'd write a loop in e.g.
Java. Typical example would be a function that uses
accumulator-passing style for implementation, but does not wish to
expose that accumulator in its public signature (as is normally the
case).

Something like that would be wonderful. I'm not specifically
interested in syntax details here, just the existence of a clear and
straightforward way to do this.

With the introduction of inline functions and function item type to
XQuery 1.1, I hoped that we'll finally get a decent looping construct
in form of inline recursive functions; e.g.:

     let $fib := function($n as xs:integer) {
        if ($n < 3) then 1 else $fib($n-1) + $fib($n+2)
     }
     return $fib(10)

The above doesn't work as is because let-bindings in XQuery cannot be
recursive, and therefore the inline function cannot reference $fib.
The usual workaround for that is to make the function take itself as
an argument, i.e.:

     let $fib := function($fib as ???, $n as xs:integer) {
        if ($n < 3) then 1 else $fib($n-1) + $fib($n+2)
     }
     return $fib($fib, 10)

But then the problem is with the declared type of the function. So far
as I can see, there's no way to declare an XQuery function type that
references itself in any way. Is that right? It is, of course,
possible to use item() as the type, and let the implementation do the
runtime check (or optimize it out), but this isn't very neat...

I wonder if some way of defining recursive bindings, where the binding
itself is in the scope of its initializer - specifically for recursive
functions - has been considered, similar to "let rec" of OCaml? It's
obvious why this isn't safe to refer to the binding in its initializer
in the most general case, but the special case of directly binding an
inline function is both perfectly safe, and should become fairly
common.

I was under the impression that an XQuery processor isn't even *allowed* to
support the namespace axis, which is why Saxon contains explicit logic to
reject it: though reading the conformance rules again, XQuery is actually
very liberal about vendor extensions, so that might not have been the right
decision.

Saxon does have a function saxon:namespace() which allows you to construct
namespace nodes and add them to a containing element, which is less
contorted than your workaround, but not as portable.

It's worth pointing out that the Data Model actually allows processors to
remove namespaces that don't appear in element or attribute names
completely. That was done because there were influential vendors on the
Working Group who simply saw "namespaces in content" as an unnecessary
complexity, and one which made mapping of XML to relational databases too
hard. I don't know if any products have taken this option - it's worth
checking, because any such product cannot be used to store schemas,
stylesheets, or even instance documents containing an "xsi:type" attribute.

I've based the section in my teaching materials on the note in:

   http://www.w3.org/TR/2007/REC-xquery-20070123/#id-basics

... just before section 2.1:

   http://www.w3.org/TR/2007/REC-xquery-20070123/#context

... where it states:

   "XQuery does not support the namespace axis and does not
    represent namespace bindings in the form of nodes.

That sounds pretty explicit to me ... but it is in a note.  Does 
putting it in a note make it informative instead of normative in W3C 
specifications?  I think in ISO specifications that is true, but 
given this was in the section on basics I thought it was binding.

Hi Hans-Juergen,

I had a similar case (or perhaps it is the same?) in which I wanted to preserve namespace bindings on the element when copying it, even those not used or only used by descendants. I simply solved it by using the namespace axis. It would come down to adding $n/namespace::* just above your for loop. But I am not certain it is supported by all XQuery processors, and you may get some xml namespace bindings you will have to filter out as well..

Kind regards,
Geert

Hello People,

glad to get advice concerning the processing of namespace-sensitive content.

The problem. When recursively processing a document with namespace-sensitive content - e.g. an XSD - one has this problem: the classic copying pattern:
      element {node-name($n)} {
         for $ac in $n/(@*, node()) return yogi:process($ac)
      }

does not copy namespace-bindings unless they will be provided by namespace fixup due to their use in item names. In particular, namespace bindings which the source may possess solely for the interpretation of namespace-sensitive content may be lost... How to deal with this problem?

The technique I use is collecting the source element's bindings (via in-scope-prefixes + namespace-uri-for-prefix), construct a wrapper around the target node, attach dummy attributes to it using the namespace bindings, and then discard the wrapper:
<_wrapper>{$nsDummayAtts, element{node-name($n)} {...}}</_wrapper>/*

which is as elegant as Monty Python's silly walks but less funny. And worse: it is a fragile solution, depending on the copy-namespaces mode containing the value 'inherit', and some (even neither bad nor cheap) processors do not even support setting that mode! Not to mention that in other parts of the same module a different mode value may be appropriate...

Does anybody have alternative suggestions how to cope with the problem (except for turning to XQuery 1.1 which will not be a recommendation within two years, and XSLT2.0)?

Thank you very much -
Hans-Juergen

Hello,

We are using mxquery 0.6.  A few months ago, I noticed a problem where our xquery updates were losing newlines.   One of my coworkers did some testing, closed it as "not a bug, cannot reproduce", but now today I've found that the problem is still happening when inserting attributes but not replacing them (which is probably what he tested).

Sample query:

declare variable $source external;
declare variable $newNote := "A note
with
some new

lines in it.";

copy $target := $source modify (
   let $targetElement := $target//<el>;
   let $notes := $targetElement/@Notes
   return (
             if ($notes) then (
                   replace value of node $notes with $newNote    (: this works fine, new lines are preserved :)
             ) else (
                   insert nodes attribute Notes '{' $newNote '}' into $targetElement  (: this loses new lines, they are replaced with a space :)
            )
   )
)
return $target

input:    <root><el /></root>
output:  <root><el Notes="A note with some new  lines in it." /></root> (incorrect, escaped new lines have been replaced with regular spaces)

input:    <root><el Notes="x" /></root>
output: <root><el Notes="A note&#X0A;with&#X0A;some new&#X0A;&#X0A;lines in it." /></root>    (correct, replace is OK)

I've been digging through the xquery update spec for a bit but I am not finding my answer - is there an extra symbol or setting we need to preserve the new lines for an insert?  Is the processor doing 'too much' normalization?  I'd be happier if it wasn't modifying data on its own. =)

Thanks in advance for any advice
-John

A result tree never contains " - that is an artefact of serializing the
result tree into lexical XML.
 
XQuery doesn't give you this amount of control over the way in which the
result tree is serialized. Generally, character and entity references will
be used only where there is no other way of representing the character.
 
You can achieve what you want by post-processing the results through an XSLT
2.0 serializer that supports character maps. This allows you to define rules
for outputting individual characters during serialization.
 
However, it's worth asking the question - why do you care? Any component
that reads this output and cares about the difference between " and "
is not using XML in the way XML was intended to be used, and your best
course of action is to fix that component.
