I'm confused as to why you have to 'increase the size of the search'. (by which I'm not sure if you mean you're just changing the allowed range within the second set of capturing parenthesis, or something else).

Could you also give some sample input, and what you would like as the output? I think that would help me understand the problem. (assuming the data that you're working with isn't confidential for some reason... which it might be, if its financial reports, based on the headers)

Update: okay, I should've looked at the two regex closer -- he's adding to the first and third capturing sets. (I still don't understand why that logic is being used, though
