+1 this (instead of Mastering Regular Expressions.)

The problem with Friedl's book, and the culture of regexes in general, is
that it leads to applying regexes to problems better worked out with any
thing from splits() to formal parsers.

As jwz put it "A lot of people, when they have a problem, think 'I know,
I'll use regular expressions!' Now they have two problems."
