RegEx
in [Ruby]

From: Justin To on 1 Jul 2008 18:18 version: 1. abc 600-qwer 2. abc600-qwer 3. abc 6.0.0-pedfs 4. abc 6.12.23-45 5. abc 5.0.6.0 etc... I want to be able to identify which version is version 6, version 5, etc.. I'm not sure if a regex is the best way. I need to be able to say that #1-4 are version 6 and #5 is version 5. But I need to be able to identify versions 1-8. Also, what if I need to identify, specifically, version 5.5 and 5.6? Thanks -- Posted via http://www.ruby-forum.com/.

Sorry about that. Firefox decided it was time to update and then posted what I had already typed. str = ['abc 600-qwer', 'abc600-qwer', 'abc 6.0.0-pedfs', 'abc 6.12.23-45', 'abc 5.0.6.0'] versions = str.map {|v| v.gsub(/\D/, '')[0,1]} => ["6", "6", "6", "6", "5"] That will get you the major version numbers. If you want minors, etc., you'll need a more specific format, I think. Otherwise, you couldn't be sure that 'abc 600-qwer' is version 6, 60, or 600. If you assume the major is a single digit: str.map {|v| v.scan(/(\d)\.?(\d+)/)[0]} => [["6", "00"], ["6", "00"], ["6", "0"], ["6", "12"], ["5", "0"]] If you know more specifics about the version format, you could get better results; particularly if you need anything beyond the minor number.
