I have a simple document:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<name>Test</name>
<description>D1</description>
<number>42</number>
<description>D2</description>
</root>
And a stylesheet that groups certain elements together:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:exslt="http://exslt.org/common";
extension-element-prefixes="exslt"
exclude-result-prefixes="exslt"
version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:variable name="tree">
<test>name</test>
<test>description</test>
</xsl:variable>
<xsl:template match="root">
<out>
<!-- process the specific nodes defined in the variable -->
<xsl:for-each select="exslt:node-set($tree)/test">
<xsl:variable name="tag" select="."/>
<results group="{$tag}">
<xsl:for-each select="/root/*[name() = $tag]">
<xsl:copy-of select="."/>
</xsl:for-each>
</results>
</xsl:for-each>
</out>
</xsl:template>
</xsl:stylesheet>
The expected output is:
<?xml version="1.0"?>
<out>
<results group="name">
<name>Test</name>
</results>
<results group="description">
<description>D1</description>
<description>D2</description>
</results>
</out>
In the case of Xalan (v2.4.1 with JDK1.4.1) the output is:
<?xml version="1.0" encoding="UTF-8"?>
<out>
<results group="name"/>
<results group="description"/>
</out>
I ran the same stylesheet with XSLTProc and got the output I expected. It is
as though the Xalan processor cannot see the root element when it is
operating within a for-each clause walking a converted nodeset. Does anyone
know if this is a know fault or is it behaving according to spec and my
expectations were wrong. Obviously there are better ways of grouping things
and I have changed the whole stylesheet but suspect I have found a problem.
