RE: counting leaf nodes

["Mike Ball" <mike.ball@xxxxxxxxxxxxxxxx>]

Hi Perry

<xsl:value-of select="count(descendant::*[not(child::*)])"/>

gives the count of leaf elements below the current element. Or

<xsl:value-of select="count(descendant::su[not(child::*)])"/>

if you only want ot count "su"s.

There may however be more efficient/elegant ways, I'm no guru.

Hope that helps
