Re: [xsl] Searching for the longest path in a tree

[Mukul Gandhi <mukul_gandhi@xxxxxxxxx>]

Hi Norman,
  Please try this XSL.. I have modularized the
stylesheet by having a named template.. I am also
assuming you are interested in element nodes only..

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output method="text" />

<xsl:template match="/">
  <xsl:call-template name="max-depth">
    <xsl:with-param name="node-set" select="//*" />
  </xsl:call-template>
</xsl:template>

<xsl:template name="max-depth">
  <xsl:param name="node-set" />
  
  <xsl:for-each select="$node-set">
    <xsl:sort select="count(ancestor::*)"
order="descending" data-type="number" />
    <xsl:if test="position() = 1">
      <xsl:value-of select="count(ancestor::*)" />
    </xsl:if>  
  </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

Regards,
Mukul
