Hello,

 thanks to everyone for their reply it helped alot. To summarise, given the 
following XML file:



<?xml version="1.0"?>
<doc>
<a>cont1</a><b id="b1"/><b id="b2"/>
<a>cont2</a><b id="b3"/><b id="b4"/>
<a>cont3</a><b id="b5"/><b id="b6"/><c/><c/>
<a>cont4</a><b id="b7"/><b id="b8"/><b id="b9"/><c/><c/>
</doc>


The following XSLT file demonstrates what I needed:-

<?xml version="1.0"?>
<xsl:stylesheet
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 version="1.0" >
  <xsl:output method="xml"/>
  <xsl:strip-space elements="*"/>
  <xsl:template match="/">
    <xsl:for-each select="//a">
      <!-- iterate over grouped b's -->
      <xsl:text>Group </xsl:text>
      <xsl:value-of select="position()"/>
      <xsl:text> </xsl:text>
      <xsl:for-each 
select="following-sibling::b[generate-id(preceding-sibling::a[1]) = 
generate-id(current()) ]">
        <xsl:value-of select="./@id"/>
      </xsl:for-each>
      <xsl:text>&#10;</xsl:text>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>


Cheers,

       Dave.
