RE: calculate depth of an xml-tree

<xsl:for-each select="//*">
  <xsl:sort select="count(ancestor-or-self::*)" data-type="number"/>
  <xsl:if test="position()=last()">
    <xsl:value-of select="count(ancestor-or-self::*)"/>
  </xsl:if>
</xsl:for-each>

Or in 2.0:

max(for $n in //* return count($n/ancestor-or-self::*))

You can possibly speed it up a little by excluding non-leaf elements, or
by using a recursive template that supplies the depth of a node as a
parameter, avoiding the need to count ancestors of every node.
