Why would you want to count them, simply recursively process the nodes with xsl:apply-templates using a mode if you have to.

eg (untested code)

<xsl:template match="menu">
	<xsl:apply-templates match="item">

<xsl:template match="item">
<!-- the leaf node -->
	<xsl:param name="parent-route"/>
	<xsl:value-of select="concat($parent-route,string(position()))"/>

<xsl:template match="item[item]">
<!-- not a leaf node -->
	<xsl:param name="parent-route"/>
	<xsl:apply-templates select="item">
		<xsl:with-param name="parent-route" select="concat($parent-route,string(position()),'.')"/>

Subject: [xsl] XPath question

Every time I think I have a good grasp on XPath, it slips between my fingers. Consider the following XML:

  <item title="Vegetables">
    <item title="tubers">
      <item title="potatoes">
  <item title="Fruits">
    <item title="Apples>
      <item>Granny Smith</item>

I have an HTML application for which I must flatten out the hierachy of this XML document, yet still maintain a link to the parent element for each child element. To this end I have decided to number each element according to its position in the hierarachy and use a "dot-delimitted" format for each element's id (i.01.03.11). I have struggled in vain today to come up with an XPath expression which would tell me how many elements are on the preceding-sibling axis of the parent of a given node. Can anyone straighten me out on this?
