RE: [xsl] grouping sequence question

[TSchutzerWeissmann@xxxxxxxxxxxxxxxx]

Hi Paul,

I don't quite understand what you're doing, but is this any use? It gives
something akin to what you want, but I'm sure it's more complicated...

<xsl:key name="byGRP"
  match="xs:element[not(starts-with(@ref, 'GRP'))]"
  use="generate-id(preceding::xs:element[starts-with(@ref, 'GRP')][1])"/>

<xsl:template match="/xs:schema/xs:element">
  <xsl:for-each select="//xs:element[starts-with(@ref, 'GRP')]">
    <xsl:variable name="me" select="generate-id()"/>
    Group is <xsl:value-of select="@ref"/> :

    <xsl:for-each select="key('byGRP',$me)">
      <xsl:value-of select="@ref"/> Starts

    </xsl:for-each>
    <xsl:for-each select="key('byGRP',$me)">
      <xsl:value-of select="@ref"/> Ends

    </xsl:for-each>
  </xsl:for-each>
</xsl:template>

</xsl:stylesheet>
