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.

Von der hinteren Coverseite

Regular expressions can make virtually every developer more productive, but many programmers don't use them because they've never learned how. In Learning Regular Expressions, best-selling author Ben Forta solves that problem. Forta's expert tutorial organizes regex into a series of easy-to-follow hands-on lessons focused on solving the specific problems you're likely to encounter most often. Instead of dwelling on syntax, terminology, and arcane scenarios, he guides you through concepts and techniques you'll use every day -- starting with simple text matches and working up to powerful backreferences, conditional evaluation, and look-ahead processing. Forta's clear, practical examples are implemented in multiple languages, so you can find code you can immediately use to get the job done.
