This provides a useful head start into regular expressions:

If you are going to go deep into regex, with or without perl, pick up
"Mastering Regular Expressions", by Jeffrey Fried.

http://regex.info/

Regular Expressions have been useful for soooooo many things, once I
understood them.  The better I understand them, the more useful they
become.  Mr. Fried's book, in it's first revision at least, was very
easy to read.
