Are you nuts? That's just the sort of thing Regexp was designed
to do.
And, it's not really all that complex.
Yes it is. The *only* correct regexps I am aware of for e-mail
addresses are on the order of a page in length. All shorter regexps
reject some valid e-mail addresses.
Thanks Marnen. I stand corrected.
However, just to clarify, are you saying that Regexp is still the
best
approach? Given that what you're saying is true, which I'm sure it
is,
then I could imagine that performing this validation without using
Regexp would be even more complex and require quite a bit more code.
The best approach is to download a plugin for email validation,
because
someone, somewhere, has already done all the work ;-)
Several some ones...
