Given input such as

<entry

<entry href="/apps/jdk/lib/fonts/LucidaTypewriterBold.ttf">Lucida</entry>
<entry
href="/apps/jdk/lib/oblique-fonts/LucidaSansDemiOblique.ttf">Lucida</entry>
</fonts>
I want to sort and group by directory, for an output such as
<fonts>
<dir href="/apps/jdk/lib/fonts">
<entry href="LucidaTypewriterRegular.ttf">Lucida</entry>
<entry href="LucidaTypewriterBold.ttf">Lucida</entry>
</dir>
<dir href="/apps/jdk/lib/oblique-fonts">
<entry href="LucidaSansDemiOblique.ttf">Lucida</entry>
</dir>
etc.
I.e. Isolate the directories, then group all entries within that directory.
<xsl:template match="fonts">
<xsl:copy>
<xsl:for-each-group select="entry"
group-by="string-join(tokenize(@href, '/')[position() lt
last()], '/')>
<dir href="{current-grouping-key()}">
<xsl:apply-templates select="current-group()"/>
</dir>
</xsl:for-each-group>
</xsl:copy>
</xsl:template
<xsl:template match="entry">
<entry href="{tokenize(@href, '/')[last()]}">
<xsl:value-of select="."/>
</entry>
</xsl:template>
Untested.
