Hi Ken,

I'm sorry or the lack of precision.

I'm stuck with XSLT 1.0 (ASP.NET) and worse, what I'm after is to get a list
of <set ... > nodes with the SelectNodes method of an XmlDocument.

I guess I might have to get these elements another way.

Thanks,
Raymond

This is one function call in XSLT 2 and some preparatory work in XSLT 
1.  You don't say what governs the order.

Examples are below ... I hope this helps.

. . . . . . . Ken

t:\ftemp>type raymond.xml
<application>
    <section id="0802">
     <set key="jazz" value="4" />
     <set key="pop" value="61" />
     <set key="rock" value="43" />
   </section>
   <section id="0803">
     <set key="jazz" value="2" />
     <set key="vocal" value="2" />
   </section>
</application>

t:\ftemp>type raymond.xsl
<?xml version="1.0" encoding="US-ASCII"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                 version="2.0">

<xsl:output method="text"/>

<xsl:key name="keys" match="@key" use="."/>

<xsl:template match="/">
XSLT 2:
<xsl:value-of select="distinct-values(//@key)" separator="&#xa;"/>
XSLT 1:
<xsl:for-each select="//@key[generate-id(.)=
                              generate-id(key('keys',.)[1])]">
   <xsl:if test="position()>1" xml:space="preserve">
</xsl:if>
   <xsl:value-of select="."/>
</xsl:for-each>
</xsl:template>

</xsl:stylesheet>
t:\ftemp>xslt2 raymond.xml raymond.xsl con

XSLT 2:
jazz
pop
rock
vocal
XSLT 1:
jazz
pop
rock
vocal
t:\ftemp>
