You can do that in two ways. You can count the number of ancestors of
the <item> element that you're on using:


Alternatively, you can pass a parameter into the template, adding one
on each recursion, as in:

<xsl:template match="item">
  <xsl:param name="ancestors" select="0" />
    <xsl:with-param name="ancestors" select="$ancestors + 1" />

If you're dealing with very deep hierarchies, using a parameter will
probably be speedier.
