xpath/xslt to determine index of context node relative to all nodes of same name?

Question

Given the schema below - with a "query" node as the context, is it possible with xpath/xslt to determine the index of that "query" node relative to all "query" nodes in the document (not position() relative to its immediate siblings).

TIA,

Geoff

Answer 1

Use:

count(preceding::question)+1

This transformation performs an exhaustive test:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt;
 <xsl:output method="text"/>

 <xsl:variable name="vQs" select="//question"/>

 <xsl:template match="/">
  <xsl:for-each select="$vQs">
    <xsl:value-of select=
    "count(preceding::question)+1"/>
    <xsl:text> </xsl:text>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

When the above transformation is applied on the following XML document:
