A newbies question on multiple groupings:

Input XML:

<?xml version="1.0" encoding="utf-8"?>
<root>
  <a title="Heavy Vehicle Driver Fatigue Reform Information">
    <g compliance_issue_title="Transport of Materials and Goods">
      <j titlelong="Commonwealth of Australia" />
    </g>
    <g compliance_issue_title="Working Hours">
      <j titlelong="Commonwealth of Australia" />
    </g>
  </a>
  <a title="Marine and Safety Regulations - Collision">
    <g compliance_issue_title="Transport of Materials and Goods">
      <j titlelong="New South Wales" />
      <j titlelong="Tasmania" />
    </g>
    <g compliance_issue_title="Emergency Preparedness and Response">
      <j titlelong="New South Wales" />
      <j titlelong="Tasmania" />
    </g>
  </a>
  <a title="Road Transport (Mass, Loading and Access) Amendment
Regulation - Fees">
    <g compliance_issue_title="Transport of Materials and Goods">
      <j titlelong="New South Wales" />
    </g>
  </a>
</root>


Output :
<root>
  <g> "Transport of Materials and Goods"
    <j> "Commonwealth of Australia"
      <a title="Heavy Vehicle Driver Fatigue Reform Information"/>
    </j>
    <j> "New South Wales"
      <a title="Marine and Safety Regulations - Collision"/>
      <a title="Road Transport (Mass, Loading and Access) Amendment
Regulation - Fees"/>
    </j>
    <j>"Tasmania"
      <a title="Marine and Safety Regulations - Collision"/>
    </j>
  </g>
  <g> "Working Hours"
    <j>"Commonwealth of Australia"
      <a title="Heavy Vehicle Driver Fatigue Reform Information"/>
    </j>
  </g>
  <g"Emergency Preparedness and Response"
    <j>"New South Wales"
      <a title="Marine and Safety Regulations - Collision"/>
    </j>
    <j>"Tasmania"
      <a title="Marine and Safety Regulations - Collision"/>
    </j>
  </g>
</root>

The XSLT I got to :

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/
Transform">
  <xsl:key name="bpjur" match="//j" use="concat(../
@compliance_issue_title,'',@titlelong)" />
  <xsl:template match="/">
    <root>
    <xsl:for-each select="//j[generate-id() = generate-id(key('bpjur',
concat(../@compliance_issue_title,'',@titlelong))[1])]">
       <g>
         <xsl:value-of select ="../@compliance_issue_title"/>
         <j>
           <xsl:value-of select ="@titlelong"/>
         </j>
       </g>
    </xsl:for-each>
      </root>
  </xsl:template>

</xsl:stylesheet>

Which gives me the following output:

<?xml version="1.0" encoding="utf-8"?>
<root>
  <g>Transport of Materials and Goods
  <j>Commonwealth of Australia</j>
  </g>
  <g>Working Hours
  <j>Commonwealth of Australia</j>
  </g>
  <g>Transport of Materials and Goods
  <j>New South Wales</j>
  </g>
  <g>Transport of Materials and Goods
  <j>Tasmania</j>
  </g>
  <g>Emergency Preparedness and Response
  <j>New South Wales</j>
  </g>
  <g>Emergency Preparedness and Response
  <j>Tasmania</j>
  </g>
</root>

Which looks promising as it has not displayed the last nodeset of :
<g>Transport of Materials and Goods
  <j>Tasmania</j>

But this is where I get stuck, I dont know how to group this resultset
to first display the unique <g> elements followed by <j> elements and
then the a/@title below it.

Any help would be appreciated.
