Perhaps I missed somthing...

As a beginner, every little bit helps and I am certainly glad that the "intelligents" such as Mr. Forta takes the time to address us who know so much less. Also, I really did enjoy both the "get to the point" and brevity of the book but, perhaps I missed something, because I was getting confused between the "TEXT" portion of his examples and the "RESULT" portions - they were always exactly the same! Once the "REGEX" portion was applied against the "TEXT", wasn't the "RESULT" portion supposed to show only what was filtered? This made the examples meaningless for me. Aside from that, the print quality wasn't there; it seemed that at some point it had become over-xeroxed at the office. Overall, at the very least, I believe the book to be a good primer. I hope to see Mr. Forta follow up somehow. Also, if you get this book, make sure to look up the 19 erratas on his website.

Excellent regex primer!

After reading this clearly written little book you will have a good understanding of what regex expressions are all about as well as a serviceable command of syntax. Follow it up with Friedl's "Mastering Regular Expressions," which will be a breeze with Forta's crash course under your belt, and you will be well on your way to guru-dom.

Excellent introduction to Regular Expressions

Regular Expressions are incredibly powerful text parsing tools. But as with almost everything, using the tools regularly is essential to maintaining and building proficiency. Of course, there are ways to work around that and this is one of them.

Not only is the book an extremely good introduction to Regular Expressions and the Regular Expressions Language, but it is also very helpful as a very quick refresher course.

Forta intends his book to be an introduction to Regular Expressions. In fact - and this shows you the nature of the man - Forta suggests another book from another publisher (Friedl's "Mastering Regular Expressions) to those who want more information.

In ten chapters, Forta walks the reader through the basics of understanding what Regular Expressions are, how they can be used and how to use them.

Overall, this is a great introduction to Regular Expressions, their user and how to forumulate them. Excellent for your first introduction or for refreshing the skills of the infrequent user.

RegEx is supported in all major development environments (for use in editing and working with code) and will thus appeal to anyone using these tools. In addition, every JavaScript developer should be using RegEx, but most don't as it has never been taught to them properly before. Developers using ASP, C#, ColdFusion, Java JSP, PHP, Perl, Python, and more can (and should) be using RegEx, and so every one of them is a potential reader too. The reader of this book will learn how to:

Match characters sets Match repeating characters (using minimums and maximums if needed) Match (or ignore) based on case Build sub-expressions Use all of the special characters Work with excape sequences Use POSIX classes to simplify complex expressions Use back-references Use look-behind operators

Sams Teach Yourself Regular Expressions in 10 Minutes is a tutorial book organized into a series of easy-to-follow 10-minute lessons. These well targeted lessons teach you in 10 minutes what other books might take hundreds of pages to cover. Instead of dwelling on syntax, terminology, and arcane examples and scenarios, this book takes a very hands-on approach to solving the needs of the majority of RegEx users who simply need to manipulate data.
