How to master Regular Expressions? [closed]

Answer 1

I use Mastering Regular Expressions from O'Reilly.

Answer 2

Reading about them is fine, but actually getting hands on experience with a tool is really helpful.

Try the Regulator - http://weblogs.asp.net/rosherove/pages/tools-and-frameworks-by-roy-osherove.aspx

Answer 3

Practice, practice, practice. I've always found Perl's manual page on regular expressions to be an excellent reference for all the common and POSIX regex symbols and commands.

Answer 4

To master them, don't stop at reading about them. Go down the list of posts tagged regex and start solving the problems. Don't peek at the answers until you're ready.

Answer 5

Perl + Roberts Perl Tutorial are the source of most of my regex ability.

Answer 6

Fix bugs in Jeff Friedl's book before he does. Until you do that, you haven't mastered regular expressions.
