Re: regexp to only allow for formally valid email addresses

You need to escape the dots in your regex.

Update: Nevermind this post. I stand corrected and learned Yet Another Perl Nuance. Thanks Thelonius & Fletch.

Unless you don't think the character classes are a bit redundant. I assume fraktalisman only wants to match \w as well as '-' and '.' since its for e-mail addresses. `# my guess is that he's not trying to do this =~ /^[.]+@[.]+$/ # either of these make more sense for matching an e-mail address =~ /^[a-zA-Z_\-\.0-9]+@[a-zA-Z_\-\.0-9]+$/ =~ /^[\w\-\.]+@[\w\-\.]+$/` [download] Or am I missing something painfully obvious?

The dot is not special within square brackets. `/[.]/` only matches ".", not "a".	[reply] [d/l]
