Re: AW: xsl:key function help

That is OK so far because I can understand. Regarding the Muenchian method
which is described on Jenis site I tried the following:

<?xml version='1.0' encoding='UTF-8'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="Categories" match="Tip" use="@Topic" />
<xsl:output method="xml"/>
	
	<xsl:template match="/">		
		<xsl:apply-templates select="Tip[generate-id(.) =
generate-id(key('Categories',@Topic)[1])]"/>
	</xsl:template>

	<xsl:template match="Tip" >
		<xsl:for-each select="key('Categories', @Topic)">
			<xsl:value-of select="@Subtopic"/>
		</xsl:for-each>
	</xsl:template>

The usage of the 'key()' function and the implementation of the Muenchian grouping is 100% correct.
The problem is really much easier:
You do not want <xsl:template match="/">
but instead: <xsl:template match="TipDatabase">
