Re: Template for node-set parents

Thanks for the suggestion. I got stuck when trying to produce a sorted node-set. Instead of a node-set, I got a result tree fragment, for which no node-set operations are possible. Here is a simplified example to illustrate the problem. Whereas it is possible to select a node from $result, it is not possible to select a node from $sorted. Any ideas?

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   <xsl:output method="xml"/>
   <xsl:template match="*">
     <xsl:copy>
       <xsl:apply-templates/>
     </xsl:copy>
   </xsl:template>
   <xsl:variable name="result" select="/response/data/result"/>
   <xsl:variable name="sorted">
     <xsl:apply-templates select="/response/data/result">
       <xsl:sort select="COMPANY_SORT" data-type="text" order="descending"/>
     </xsl:apply-templates>
   </xsl:variable>
   <xsl:template match="/">
     <xsl:copy-of select="$result[1]"/>
     <xsl:copy-of select="$sorted[1]"/>
   </xsl:template>
</xsl:stylesheet>

Try:

1. define a global variable $v1 that selects the result of the path expression in document order.

2. define another global variable $v2 that selects the sorted result of the path expression

3. Use a base template rule that's the identity copy

4. Add a template rule that matches nodes in $v1 (match="node()[. intersect $v1]). In this rule, determine the index position of this node in $v1 (count ($v1[. << $this]) + 1), and output the corresponding node from $v2 (copy-of select="$v2[$n]").

I am trying to generate a stylesheet that copies an XML source document. The only change should be that nodes selected by an XPath expression are sorted. I want this to work for any XML source document. The only information available to generate the stylesheet is the XPath expression and the sort criteria. I think this requires creating a template for the parents of the nodes selected by the XPath expression. How can I do this?
