applying exslt:node-set to a node set yields something that is not a node set
-----------------------------------------------------------------------------
Key: XALANJ-2524
URL: https://issues.apache.org/jira/browse/XALANJ-2524
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in
Xalan projects. Anybody can view the issue.)
Components: Xalan-extensions
Affects Versions: 2.7.1
Reporter: Julian Reschke
Priority: Minor
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.
