Hi Andrew,
Thanks for the help but unfortunately this is not giving me the results I
desire. When I run that, it returns an empty set. It also takes a long
time to run. There is no way to use the Muenchian method but base it on
another value in the node?
You didn't say you had a large input set or that performance was
important... This stylesheet uses two keys, one to filter based on
genre, the other to group by Artist (which is the Muenchian method :)
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:key name="song-by-genre" match="song" use="Genre"/>
<xsl:key name="song-by-artist" match="song" use="Artist"/>
<xsl:param name="genre" select="'Rap'"/>
<xsl:template match="/">
<xsl:apply-templates select="key('song-by-genre', $genre)"/>
</xsl:template>
<xsl:template match="song">
<xsl:if test="generate-id() = generate-id(key('song-by-artist', Artist)[1])">
<xsl:value-of select="Artist"/>
<xsl:if test="position() != last()">, </xsl:if>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
cheers
