Regular Expression Help Needed

[David A McInnis]

But if the email address is enclosed in html, then it should be pretty easy
to snag, right.  Just pull out everything between <a href="mailto:  and ">.
Anyway, that is my understanding, but I don't know how to make it happen.  I
will go check out this book tomorrow.  Let me know if you have any other
thoughts.

David

Get a copy of _Mastering Regular Expressions_, by Jeffrey Friedl, from
O'Reilly press. The regular expression you want is in the back.

Be warned - it's over 4000 characters long, and it still doesn't work in all
cases. Email addresses are not a regular language, and therefore cannot be
completely matched by regular expressions.
