Learn to use one of the most powerful text processing and manipulation
tools available
Regular expression experts have long been armed with an incredibly
powerful tool, one that can be used to perform all sorts of
sophisticated text processing and manipulation in just about every
language and on every platform. That's the good news. The bad news is
that for too long, regular expressions have been the exclusive property
of only the most tech savvy. Until now.
Ben Forta's Learning Regular Expressions teaches you the regular
expressions that you really need to know, starting with simple text
matches and working up to more complex topics, including the use of
backreferences, conditional evaluation, and look-ahead processing.
You'll learn what you can use, and you'll learn it methodically,
systematically, and simply.
Regular expressions are nowhere near as complex as they appear to be at
first glance. All it takes is a clear understanding of the problem being
solved and how to leverage regular expressions to solve them.
