xsl test multiple
I found something.

didn't realize you could concat multiple nodes together as part of a variable:

<xsl:variable name="all_publications">
	<xsl:copy-of select="*[starts-with(name(),'publications_')]"/>
</xsl:variable>

This is working, so i'm ok unless you have better ideas.

Thanks,
jonathan

Hi all,


I'm sure i should be spending more time on this myself, but i'm in a bit of a time crunch and i can't seem to find what i'm looking for.

I'm trying to test to see if multiple nodes contain a value.
xml is like:

<publication_1>a publication</publication_1>
<publication_2>a publication</publication_2>
.
.
.
<publication_n>a publication</publication_n>

i want to do, in pseudocode
<xsl:if test="any node which starts with publication_ has a value">
	do something
</xsl:if>

is it possible to concatenate string values of a nodeset together? (in xsl 1.0)
something like:
<xsl:test select="concat(*[starts-with(name(),'publication_')]) !='' ">



again, this may be simple. sorry. I wish i had more time to research it on my own.


Thanks for any help,
jonathan

Hello Susan,

<sw:stop>
<word>the</word>
<word>a</word>
<word>an</word>
</sw:stop>
<xsl:variable name="stop-words" select="document('')/xsl:stylesheet/sw:stop/word"/>


I didn't know this was possible? Selecting elements from the stylesheet by using document('')
Anyway, it didn't work for me... so I put the stop-words in a separate file and used
"document('stop-words.xml')/stop/word" instead; that worked.


(I also corrected the "uppercase" variable: the last 4 chars are missing)

Then, after some experimenting, I succeeded in sorting twice, with empty titles included,
simply by omitting [text()!=''] from your first for-each select. Like this:


<xsl:for-each select="//section-02/title"> <!-- removed [text()!=''] -->
<xsl:sort select="concat(substring(substring-after(.,' '), 0 div boolean
($stop-words[starts-with(translate(current(), $uppercase, $lowercase),
concat(translate(., $uppercase, $lowercase), ' '))])), substring(., 0 div not
($stop-words[starts-with(translate(current(), $uppercase, $lowercase),
concat(translate(., $uppercase, $lowercase), ' '))])))"/>


<xsl:sort select="number(concat(substring(../arrival-date, 7,4),
substring(../arrival-date, 1,2), substring(../arrival-date, 4,2)))" order="descending"/>
<!-- added ../ -->


     <tr>
      <td width="10%"><xsl:value-of select="../doc-number"/></td>
      <td width="30%"><xsl:value-of select="../title" /></td>
      <td width="10%"><xsl:value-of select="../isbn-issn"/></td>
      <td width="20%"><xsl:value-of select="../imprint"/></td>
      <td width="20%"><xsl:value-of select="../description"/></td>
      <td width="10%"><xsl:value-of select="../arrival-date"/></td>
     </tr>
    </xsl:for-each>

You were really close, I guess... I hope I didn't miss something, but I think it works now

Best regards,
Anton Triest
