Hi Karl,
I have written the following XSL to illustrate the
concept --
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan">
<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
<xsl:template match="/A">
<xsl:variable name="var">
<xsl:call-template name="get-subset-xml">
<xsl:with-param name="param" select="child::B"/>
</xsl:call-template>
</xsl:variable>
<!-- using variable var -->
<xsl:value-of
select="count(xalan:nodeset($var)/B/*)" />
</xsl:template>
<xsl:template name="get-subset-xml">
<xsl:param name="param"/>
<xsl:copy-of select="$param"/>
</xsl:template>
</xsl:stylesheet>
A nodeset function is being used, *to use the Result
Tree Fragment(RTF), returned by the template
"get-subset-xml" *. I have used nodeset, for
illustration purpose..
I hope the explanation is useful..
Regards,
Mukul

Hello,
I need a template to return a subset of XML from the
xml source. I'm trying
to populate a variable with this information. How
can I do this?
Example:
<A>
<B>
<ASDF/>
<QWEA/>
<FEASI/>
</B>
<C/>
</A>
So, a template that will return (as an example) <B>
and its subset of data.
Something like
<xsl:template name="get_subset_xml">
.... select the <b> node
</xsl:template>
More importantly, how do I assign a variable to this
new subset?
So:
<xsl:variable name="some_subset"
select="get_subset_xml"/>
where $some_suset is:
<B>
<ASDF/>
<QWEA/>
<FEASI/>
</B>
Is this possible?
Karl
