No, that won't be the case, the problem hasn't much relevance since I try
to get a good solution just for interest. But when I wrote the
stylesheets, I noticed a huge difference in runtime. Because of that I
decided to ask some pro's.

That was fact until Michael gave me the hint to do it in a recursive way.

Thank you! I searched the inet for some "best practice" patterns and how
to write performant XSL, but I must admit that I did not spent too much
time in that. Further I hope I'm learning to code better XSL by reading
this XSL-List.
