Flatten a specific branch? Partial Flatten? Help with a tree problem...

Hi...
I got something like this:

Is there a way where I can flatten some specific branch or partially flatten the seconds "levels" branchs?
What I really need is the length for every set and the problem is that after the intersection component, the length is different for each set of intersections points (even I got some "nulls" results).
In the image is just a coincidence that each set have 19 elements.

I was thinking in a vb.net component with the "param viewer" as input,
that get the second char of the first line (ej: 0) and count until the line change to the next number (1) and put the counter on a list. Then do the same with the next number (1) and so on... the output will be the counter list.
I dont know how to do this in vb.net but tomorrow im gonna give it a try.

Any tips and suggestions are welcome.. thanks.
