Regular expressions are not difficult and come in very handy. Just
bear in mind that they aren't applicable in every situation nor will a
single regex solve eveyr problem. If you try to use a single regex to
solve every problem in the world, you'll fry your mind. But if you
apply them in contexts where they are appropriate and keep them
simple, you'll enjoy using them and letting them take a lot of work
off your hands.
If you want a book to read, "Learning Regular Expressions" (or
something similar to that) by Jeffrey Friedl, published by O'Reilly,
is a very good introduction. The old revision I have is out of date
when it refers to python's regex engine, and maybe some others too,
however the general idea is still sound and I've heard that a new
edition is available.
