Re^2: regexp match repetition breaks in Perl

That's looks too lax to me. /(?:,|and)\s\d{3}\D/ is too likely to exist. For example, your regexp would match "134" in "sections 3 and 134".

Yes, although my way works for the data given it could easily break down as you point out. Your method is safer. I'm wondering why the OP captures the 'APC' and 'APCs' strings; they seem to have no bearing on how many sets of digits follow. Cheers, JohnGG	[reply]

I suspect it's just for debugging and that lima1 had the right idea when he/she put the numbers in a hash to filter out duplicates.	[reply]
