a bit of distraction ' quiz of XSLT 1.0 oddities'

a bit of distraction for those who must work.

I am generating a little 'quiz of oddities' for XSLT 1.0, some of which
I have bumped into from time to time....none are particularly mind
blowing, though some may make one stop and think.

Here are some of mine....(xsl:stylesheet elements have been stripped),
any more good questions out there ? Answers sometime around new years.

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

Whats the output

XML
<root>
    <test>1</test>
    <test>2</test>
    <test>3</test>
    <test>4</test>
</root>

XSLT
<xsl:template match="root">
    <xsl:apply-templates select="test"/>
</xsl:template>

<xsl:template match="*"> this template
    <xsl:value-of select="."/>
</xsl:template>

<xsl:template match="node()"> that template
    <xsl:value-of select="."/>
</xsl:template>

When matching templates are equivelent which one gets matched?

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

What does the string-length() function return in the following
xml / xslt snippet ?

XML
<doc>
<a>Testing this</a>
<a>and this too</a>
</doc>

XSLT
<xsl:template match="/">
  <out>
    <xsl:value-of select="string-length()"/><xsl:text> </xsl:text>
    <xsl:value-of select="string-length(doc/a)"/>
  </out>
</xsl:template>

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

Can a template be both named and match? for example is the following
construction possible?

<xsl:template name="my:book" match="book"> 

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

Does exclude-result-prefixes defined on an xsl:stylesheet element apply
to subtrees included with xsl:include ?

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

Is there any way of using apply-templates using a mode 'decided' at run
time ?

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

What does this do?

        <xsl:value-of select="name()"><a>some text</a></xsl:value-of>

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

Can anyone show a clever use of the why one would use the floor()
function specifically in XSLT 1.0 ?

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

How does one arrive to this xml

<?xml version="1.0" encoding="UTF-8"?>
<out>doc #1:
<bdd>http://example.com</bdd><ext>http://test.extension</ext><jad>http://administrator.com</jad><java>http://xml.apache.org/xslt/java</java><ped>http://tester.com</ped><xml>http://www.w3.org/XML/1998/namespace</xml>
doc #2:
<xml>http://www.w3.org/XML/1998/namespace</xml>
</out>

from this xml ?

<?xml version="1.0"?>
<docs>
  <doc x="x" y="y" z="z"
    xmlns:ext="http://test.extension"
    xmlns:java="http://xml.apache.org/xslt/java"
    xmlns:ped="http://tester.com"
    xmlns:bdd="http://example.com"
    xmlns:jad="http://administrator.com"/>
  <doc x="ax" y="ay" z="az"/>
</docs>

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

Is the following a valid declaration for xsl:variable?


<xsl:template match="/">

	<xsl:value-of select="$myvar"/>

</xsl:template>

<xsl:variable name="myvar" select="'test output'"/>


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

Which XSLT processors fully support EXSLT node-set extension ?

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

When there is no xsl:output element how does an XSLT processor determine
that you want an html result ?

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

How does FXSL calculate sin() ?

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

Is there anyway to achieve a conditional inclusion (e.g. conditionally
use xsl:include) ?

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

I have a few more.....pls send your questions, will compile and perhaps ask DaveP to include in XSLT FAQ.

cheers, Jim Fuller
