Joe,
It's something like this but each group must have placed inside a div and I 
have to not display (or hide) the div if there's no data.
And more I have to perform some test on the 
substring-before(substring-after(substring-after(lnk,'http://mywebsite/'),
>> '/'), '/')" function to display a customized title.
So I think I will be able to do it if I could store each node by category in 
distinct variables (sorry for the limited english).
