Heh--there's actually a famous regexp (if you can imagine such a thing) that faithfully tracks the RFA spec for e-mail addresses. It's something like half a printed page long and would make a kick-ass tattoo.
I'm writing from the bus, else I'd google up a link to it. But lots of much much simpler regexps will handle 99% of valid addresses. Those are easily googled up... -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of David Liwoch Sent: Thursday, September 11, 2008 12:40 AM To: Ruby on Rails: Talk Subject: [Rails] Re: HowTo search a string for content?
