If I may add another thought along the same line: regular expressions

for dense guys like myself, regular expressions work best if you use
them as simple tokenizers, and they suck pretty badly if you're trying
to use them as parsers.

I still don't touch regular expressions... They may be fast, but to
me they are just as much line noise as PERL... I can usually code a
partial parser faster than try to figure out an RE.
Yes, it seems to me that REs are a bit hit and miss - the only way to
tell if you've got a RE right is by

successful. However, creating a full email validator is way beyond me -
the rules are far too

an email address is valid? was Try sending mail to it.
There are advantages to the regex method. It is faster than sending an
email and getting a positive or negative return code. The delay may not
be

Hi,My $0.02:re.compile('^\w+([\.-]?\w+)[EMAIL PROTECTED]([\.-]?\w+)*\.(\w{2}|(com|net|org|edu|intl|mil|gov|arpa|biz|aero|name|coop|info|pro|museum))$')I picked it up from the Net, and while it may be not perfect (you've got lots of reply's telling you why),it's good enough for me.Good luck,Sorin--
Hi,
I am trying to get a regexp to validate email addresses but can't get
it quite right. The problem is I can't quite find the regexp to deal
with ignoring the case [EMAIL PROTECTED], which is not valid. Here's
my attempt, neither of my regexps work quite how I want:

Hi,
thanks for the advice guys.
Well took the kids swimming, watched some TV, read your hints and
within a few minutes had this:
r = re.compile(r'[EMAIL PROTECTED]@\s]+\.\w+')
This works for me. That is if you have an invalid email such as
tony..bATblah.com it will reject it (note the double
