Roger,

I think an iteration algorithm would be more straight forward (and this is subjective). I would break the task in two parts, first iterating through all of your strings to match and having an out1, out2, etc for each string to match. I would use a subroutine to perform this task of creating the out-n lines.

Then I would code another paragraph to collapse all of the out lines together in the least number possible output lines, once using iteration and an array to keep track of the output line 'depth' (i.e. output_line_1, output_line_2, etc)... there are dozens of ways to approach this though...

Good luck,

Pancho
