Re: Positional Grouping Problem

I'd use keys for this, something like

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
 
<xsl:output method="xml" indent="yes" /> 
   
<xsl:key name="z" match="Z" use="string(preceding-sibling::Z[.='YES'][1])"/>

<xsl:template match="/X">  
  <X>
     <xsl:apply-templates select="Y" />        
  </X> 
</xsl:template>
 
<xsl:template match="Y">
   <Y>
   <xsl:for-each 
select="Z[generate-id()=generate-id(key('z',string(preceding-sibling::Z[.='YES'][1])))]">
    <group>
      <xsl:copy-of 
select="key('z',string(preceding-sibling::Z[.='YES'][1]))[not(.='YES')]"/>
    </group>
      <xsl:copy-of 
select="key('z',string(preceding-sibling::Z[.='YES'][1]))[(.='YES')]"/>
   </xsl:for-each>
   </Y>
</xsl:template>



 </xsl:stylesheet>
