A great book if you really need to get into complex regex. Very Helpful,
December 01, 2005 Adequate for beginners...,
May 27, 2005Excellent Introduction to Regular Expressions,
April 19, 2005 As an introduction to regular expressions, this book does an excellent job of covering the many different ways in which regular expressions are used. Included are explanations of how to put regular expressions to use in client-side Javascript, Microsoft Word, Open Office, C#, PHP, Perl, ASP, etc (Just a few that I could think of off the top of my head). I especially like that the author didn't focus on only Microsoft products, or only on open source products. He gives an excellent introduction to how regular expressions fit in in both the world of programming, and simply using your computer from day to day. This is a huge book, and Mr. Watt does a fantastic job of covering both syntax (nuts and bolts) and real-world application. This is an excellent starting point for anyone wanting to more about Regular Expressions.Good Description of what I've Been Doing But Didn't Know It,
March 04, 2005 I picked this book up because I had no idea just what a Regular Expression was. Turns out that regular expressions are nothing more than the "wildcards" from a lot of applications like Microsoft Word that have been generalized to fit a lot of applications in text processing.
For instance you may want to examine an incoming field from an internet form. If the data is going to a social security column in a database, you want to be sure that the data doesn't say something like Fred-34-1234. It's the right format, but alpha isn't a good thing to have there. If this isn't checked form, it may wait until the SQL Insert statement blows up.
The generalized form of expressions like this can be used to check things like SSN formats, the proper formation of an e-mail address and a lot of other things commonly needed in text processing.
Many languages both programming and scripting have provisions built into them to handle this kind of text processing. This book provides the generalized background to use regular expressions in ways that that you haven't considered but which you'll find very useful.
