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

  count(ancestor::item)

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:apply-templates>
    <xsl:with-param name="ancestors" select="$ancestors + 1" />
  </xsl:apply-templates>
</xsl:template>

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

Cheers,
