Julian Reschke commented on XALANJ-2524:
----------------------------------------
A wild guess is that the problem is actually in Extensions.nodeset() which
claims
* section 11.1 of the XSLT 1.0 Recommendation. If the argument is a
* node-set, <code>nodeset</code> returns a node-set. If the argument
but doesn't seem to have any specific code for Object rtf being a node set,
thus defaults to string processing.
> applying exslt:node-set to a node set yields something that is not a node set

> Applying the exslt:node-set extension to something that already is a node set
> yields a non-node set result.
> This is a bug according to
> <http://exslt.org/exsl/functions/node-set/exsl.node-set.html>:
> "If the argument is a node-set already, it is simply returned as is."
> Test case:
> <?xml version="1.0" encoding="UTF-8"?>
> <xsl:stylesheet version="1.0"
> xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
> xmlns:exslt="http://exslt.org/common";
> >
> <xsl:output method="text"/>
> <xsl:template match="/">
>
> <xsl:variable name="t">
> <root>
> <x>1</x>
> <x>2</x>
> <x>3</x>
> </root>
> </xsl:variable>
> <xsl:variable name="tns1" select="exslt:node-set($t)/root/x"/>
> <xsl:variable name="tns2" select="exslt:node-set($tns1)"/>
>
> Type of t: <xsl:value-of select="exslt:object-type($t)"/>
> Type of tns1: <xsl:value-of select="exslt:object-type($tns1)"/>
> Name of tns2: <xsl:value-of select="exslt:object-type($tns2)"/>
>
> </xsl:template>
> </xsl:stylesheet>
> This yields the expected result in xsltproc, Saxon 6.* and XSLTC, but not in
> Xalan-J.
