Re: counting nodes based on text within

If you know the values of choices, you can do the following:

<xsl:value-of select="count(/thexml/line/choice[.='item a'])"/>

A more generic version you can have with keys. My example uses the Muenchian
Method (http://www.jenitennison.com/xslt/grouping/muenchian.xml).

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output indent="yes"/>
  <xsl:key name="choices" match="choice" use="text()"/>

  <xsl:template match="thexml">
    <xsl:for-each select="line/choice[count(.|key('choices',text())[1])=1]">
      <xsl:value-of select="text()"/>
      <xsl:value-of select="count(key('choices',text()))"/>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

Hope this helps,

Joerg
