[xsl] removing nodes according to attibute value

["Charles Ohana" <charles.ohana@xxxxxxxxxxxxxx>]

Hello friends,
I'm trying to remove all elements that have a specific attribute containing 
some characters.
See example below... I need to remove all 
/ApplicationCatalogue/Category/Product that have @code starting with TT.
It has to be generic as the xml provided can have more attributes & 
elements.
Also I would need to remove the /ApplicationCatalogue/Category if it doesn't 
have any Product left after the removal
Any idea ??? Thanx a million ...
