Slightly OT, but when your regex is going to contain a lot of backslashes, I find it is a lot easier to read if you change the regex delimiter to something other than '/', like maybe '#' or '!'. Also you can use character classes (square brackets) around characters like '/' to help out some too. I can't stand reading regexes that contain escaped slashes and backslashes that still use '/' as the delimiter. They can cause brain damage.

But yeah, if Regex::Common or something already posted here can deal with it, good deal.
