Hello,

possibly a dump question, but I have not been finding what I was looking for some time.

My XML(excerpt):
---------------

<thesaurus>
<term>
<title>defense</title>
<narrowerterm>defense skills</narrowerterm>
<narrowerterm>defense actions</narrowerterm>
</term>
<term>
<title>defense skills</title>
<broaderterm>defense</broaderterm>
<narrowerterm>skill cd</narrowerterm>
<narrowerterm>skill xy</narrowerterm>
<narrowerterm>skill ab</narrowerterm>
</term>
<term>
<title>defense actions</title>
<broaderterm>defense</broaderterm>
<narrowerterm>actions against xy</narrowerterm>
<narrowerterm>actions against ab</narrowerterm>
</term>
</thesaurus>
---------------

MY XSL:
---------------
<xsl:template match="thesaurus">
<html>
<body>
<xsl:for-each-group select="term" group-by="title">
<xsl:sort select="title"/>
<xsl:choose>
<xsl:when test="broaderterm">
</xsl:when>
<xsl:otherwise>
<xsl:choose>
<xsl:when test="use">
</xsl:when>
<xsl:otherwise>
<p>
<xsl:value-of select="current-grouping-key()"/><br/>
<xsl:for-each select="narrowerterm">
.<xsl:value-of select="."/><br/>
<xsl:for-each select="???"/>
..<xsl:value-of select="narrowerterm"/><br/>
</xsl:for-each>
</xsl:for-each>
</p>
</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</body>
</html>
</xsl:template>
---------------

What I want
---------------

defense
.defense actions
..actions against ab
..actions against xy
.defense skills
..skill ab
..skill cd
..skill xy

---------------

That's where I am
---------------

defense
.defense skills
.defense actions

---------------

Basically there are two things I need to figure out:

1) multilevel sorting

2) on the third level where I put the ???: how to select another <term> which has the <title> that equals the <narrowerterm> of the <term> currently use.

I hope this is clear enough.

Thanks a lot!

All the best

KK
