Re: Recursively traversing an outline with level gaps

Nobody needs the copyrighted files. I was asking for sample files.
This is a *class of problems* and many sample files (not only the
copyrighted ones exist). Or are you attempting to copyright all xml
files that are appropriate samples for this problem? :)

Please, do understand that by not providing well-defined problem, you
are severely decreasing the chances of somebody willing to spend their
time guessworking.
