From web at polynate.net Sat Mar 26 04:00:58 2016 From: web at polynate.net (Nathan Bailey) Date: Sat, 26 Mar 2016 22:00:58 +1100 Subject: [Melbourne-pm] How to parse n matches out of a string? Message-ID: Is there a 'best practice' idiom for parsing out multiple matches from a string, ie. 'blahMatchblah blah blahMatch blah blahMatchblah' Previously I've done: while (my ($match,$rest) = $string =~ m#(Match)(.*)) { $string = $rest; } which works, but seems inelegant. Is there a better/recommended way? cheers, Nathan -------------- next part -------------- An HTML attachment was scrubbed...
