( #3333=superdoc: print w/ replies, xml ) Need Help??

The problem is not with the (\w{2,}?), because it will happily match to ab in

$x =~ /((\w{2,}?).*\g2.*?)+/;

and

$x =~ /((\w{2,}?).*?\g2.*?)+?/;

You are asking the regex to give you a sequence which is repeated, and you can either get the longest match (greedy) or the shortest one (ungreedy)

The only solution for your problem that I can think of, is to capture all matches that this regex finds (list context), then counting how often each captured sequence occurs, and selecting the one that occurs most often.
