Re: Finding the maximun number of nodes

Hello Michael,
 here is the solution:

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

<xsl:variable name="maximum">
 <xsl:apply-templates select="table" mode="howmany"/>
</xsl:variable>

<xsl:template match="/">
 <table columns="{substring-before($maximum,'~')}">
  <!-- ...  -->
 </table>
</xsl:template>

<xsl:template match="table" mode="howmany">
  <xsl:apply-templates select="tr" mode="howmany">
   <xsl:sort select="count(td)" order="descending" data-type="number"/>
  </xsl:apply-templates>
</xsl:template>

<xsl:template match="tr" mode="howmany">
 <xsl:value-of select="count(td)"/>
 <xsl:text>~</xsl:text>
</xsl:template>

</xsl:stylesheet>

Output:
=======
<?xml version="1.0" encoding="utf-8"?>
<table columns="3"/>
