The filter expression has to be on the select for the xsl:for-each or else there would be fewer sort
values than actual items.

This XSL:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:msxsl="urn:schemas-microsoft-com:xslt"
 exclude-result-prefixes="msxsl">
 <xsl:output indent="yes" method="xml" omit-xml-declaration="no"/>
 <!-- Sorted nodelist -->
 <xsl:variable name="rtf-sorted-nodeset">
  <xsl:for-each select="/Objects/SingleObject[@DisplayName='Description']">
   <xsl:sort select="DisplayValue"/>
   <xsl:copy-of select="."/>
  </xsl:for-each>
 </xsl:variable>
 <!-- convert RTF to node-set -->
 <xsl:variable name="sorted-nodeset" select="msxsl:node-set($rtf-sorted-nodeset)/*"/>
 <xsl:template match="/">
  <items>
   <xsl:for-each select="$sorted-nodeset">
    <xsl:copy-of select="."/>
   </xsl:for-each>
  </items>
 </xsl:template>
</xsl:stylesheet>

On this XML:

<Objects>
 <SingleObject id="1" DisplayName="Description">
  <DisplayValue>Item1</DisplayValue>
 </SingleObject>
 <SingleObject id="1a" DisplayName="NotADescription">
  <DisplayValue>Item1a</DisplayValue>
 </SingleObject>
 <SingleObject id="3" DisplayName="Description">
  <DisplayValue>Item3</DisplayValue>
 </SingleObject>
 <SingleObject id="2" DisplayName="Description">
  <DisplayValue>Item2</DisplayValue>
 </SingleObject>
 <SingleObject id="4" DisplayName="NotADescription">
  <DisplayValue>Item4</DisplayValue>
 </SingleObject>
</Objects>

Produces:

<?xml version="1.0" encoding="UTF-16"?>
<items>
 <SingleObject id="1" DisplayName="Description">
  <DisplayValue>Item1</DisplayValue>
 </SingleObject>
 <SingleObject id="2" DisplayName="Description">
  <DisplayValue>Item2</DisplayValue>
 </SingleObject>
 <SingleObject id="3" DisplayName="Description">
  <DisplayValue>Item3</DisplayValue>
 </SingleObject>
</items>

Which I believe achieves what you wanted?

Hi there,

I tried to find a solution on the newsgroup but even though lots of
threads look at similar problems I could not find a solution.

I have a xsl sheet that works fine this way:

...
<xsl:variable name="rtf-sorted-nodeset">
 <xsl:for-each select="/Objects/SingleObject">
  <xsl:sort select="Attributes/Attr[DisplayName='Description']/DisplayValue"/>
  <xsl:copy-of select="."/>
 </xsl:for-each>
</xsl:variable>

<!-- convert RTF to node-set -->
<xsl:variable name="sorted-nodeset"
select="msxsl:node-set($rtf-sorted-nodeset)/*"/>
<xsl:template match="/">
...

But if I want to pass in that sort value as parameter value I get into
trouble with the 'Description' part of the XPath expression. I tried:

<xsl:param name="paramSortAttr1"
select='"Attributes/Attr[DisplayName='Description']/DisplayValue"'>

and

<xsl:param name="paramSortAttr1"
select="'Attributes/Attr[DisplayName='Description']/DisplayValue'">
and all kind of &quot; and &apos; combination.

In the sort section I try to get the param value with
<xsl:sort select="*[name() = $paramSortAttr1]"/>

But like I said, the second approach does not work.

Can anybody give me an idea what is wrong?

Thank you very much,
Kai
