Regular expressions are an extremely powerful tool for manipulating text and data. They are now standard features in a wide range of languages and popular tools, including Perl, Python, Ruby, Java, VB.NET and C# (and any language using the .NET Framework), PHP, and MySQL.
If you don't use regular expressions yet, you will discover in this book a whole new world of mastery over your data. If you already use them, you'll appreciate this book's unprecedented detail and breadth of coverage. If you think you know all you need to know about regularexpressions, this book is a stunning eye-opener.
As this book shows, a command of regular expressions is an invaluable skill. Regular expressions allow you to code complex and subtle text processing that you never imagined could be automated. Regular expressions can save you time and aggravation. They can be used to craft elegant solutions to a wide range of problems. Once you've mastered regular expressions, they'll become an invaluable part of your toolkit. You will wonder how you ever got by without them.
Yet despite their wide availability, flexibility, and unparalleled power, regular expressions are frequently underutilized. Yet what is power in the hands of an expert can be fraught with peril for the unwary. Mastering Regular Expressions will help you navigate the minefield to becoming an expert and help you optimize your use of regular expressions.
Mastering Regular Expressions, Third Edition, now includes a full chapter devoted to PHP and its powerful and expressive suite of regular expression functions, in addition to enhanced PHP coverage in the central "core" chapters. Furthermore, this edition has been updated throughout to reflect advances in other languages, including expanded in-depth coverage of Sun's java.util.regex package, which has emerged as the standard Java regex implementation.Topics include:
- A comparison of features among different versions of many languages and tools
- How the regular expression engine works
- Optimization (major savings available here!)
- Matching just what you want, but not what you don't want
- Sections and chapters on individual languages
Written in the lucid, entertaining tone that makes a complex, dry topic become crystal-clear to programmers, and sprinkled with solutions to complex real-world problems, Mastering Regular Expressions, Third Edition offers a wealth information that you can put to immediateuse.
Reviews of this new edition and the second edition:
"There isn't a better (or more useful) book available on regular expressions."
--Zak Greant, Managing Director, eZ Systems
"A real tour-de-force of a book which not only covers the mechanics of regexes in extraordinary detail but also talks about efficiency and the use of regexes in Perl, Java, and .NET...If you use regular expressions as part of your professional work (even if you already have a good book on whatever language you're programming in) I would strongly recommend this book to you."
--Dr. Chris Brown, Linux Format
"The author does an outstanding job leading the reader from regexnovice to master. The book is extremely easy to read and chock full ofuseful and relevant examples...Regular expressions are valuable toolsthat every developer should have in their toolbox. Mastering RegularExpressions is the definitive guide to the subject, and an outstandingresource that belongs on every programmer's bookshelf. Ten out of TenHorseshoes."
--Jason Menard, Java Ranch
"Indispensable for text processing wizards and regex newcomers alike." - Paul Hudson, Linux Format, February 2007 "In addition to the sheer volume of information, one thing that sets this book apart is that the author uses "real-world" rather than contrived examples. A few of the examples were situations that I have yet to come across, but many were either "been there, done that" or things that I had to go out and try." - James Mohr, Linux Magazine, April 2007商品の説明をすべて表示する
My only complaint is the fonts. Both the text of the book and the source code. The font used for the regular text is very light, I would have preferred a larger, darker, and more bold font. The font used for the source code is absolutely horrible. There are little angle brackets used to identify a block (for example to highlight what has changed from the prior example). They are almost impossible to see. This is important because the author is constantly referring to the highlighted portions. Some pages are darker print than others, its inconsistent.
If another edition of this book is ever made, I would like to see larger more bold font, and use a completely different method to "highlight" portions of text in the code samples.
I wonder if this font issues occur in the Kindle edition...?
I took this on work travel when I got it, and read it on the plan. The tips for working your way through interpreting regular expressions are very good, and easier to understand than the expressions themselves.
It is NOT language specific, so you need to deal for yourself, with differences between say, how Python does it, and how Perl does it.
This should probably be in most programmers' libraries.
The book is easy to understand and you can apply it immediately.
This book saved me so much time and got my research going!
By not asserting himself as a mathematical authority, Friedl lets his cleverness come through in a practical, 'human-to-human' way. There are a few moments when the more theoretically minded reader might want a little more detail, but the balance Friedl keeps is beyond admirable.
In the entire book there are perhaps only a half-dozen pages that are 'challenging' to the mind, yet by the time the reader has finished the book he or she will be amazed, simply amazed, at the complexity of regular expressions that can be interpretted with ease. Of course, writing expressions takes more practice, but the regex muscles won't even notice the feather-light daily tasks of, say, basic data validation after working out on this text.
The book will start the reader looking for possible regex solutions everywhere, and provides enough detail to take the fear out of using them.
