[xsl] factorising elements as "country"

[FEDOU <Nfedou@xxxxxxxxxxxx>]

Hi, I'm french so their might be some mistake in my mails, sorry for those.

My original XML file is a series of database's row as :
<ROW MODID="6" RECORDID="12643562">
  <Country>France</Country>
  <Town>Paris</Town>
  <Location>Espace Saint-Martin</Location>
  <Adr1>199 bis, rue Saint-Martin</Adr1>
  <Adr2/>
  <Tel>01 02 03 04 05</Tel>
  <Expo>Artcolle 2003 : 10ème salon international du collage
contemporain</Expo>
  <Date>20/07/2003 - 27/04/2003</Date>
</ROW>

I need something like :
<Calendar>
  <Country>France
    <Town>Paris
      <Location>Espace Saint-Martin
      <Adr1>199 bis, rue Saint-Martin</Adr1>
      <Adr2/>
      <Tel>01 02 03 04 05</Tel>
        <Expo>Artcolle 2003 : 10ème salon international du collage
contemporain</Expo>
        <Date>20/07/2003 - 27/04/2003</Date>
        <Expo>2nd Expo at same location</Expo>
        <Date>2nd Expo begin and end</Expo>
      </Location>
      <Location>2nd Location, same country/town in original file
      <Adr1&2+Tel />
      </Location>
    </Town>
    <Town>Next town in same country
      <its several child>
    </Town>
  </Country>
  <Country>Next country</Country>
</Calendar>

I did some sorting and I obtained a hierarchical Tree as the one shown.
I can't figure out how to output each country, town and location only ONCE !
As preceding:: axis don't look the sorted list.
As first() is the first of all coutries.

Thanks for your help.

Best regards, nicolas Fédou.
