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

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
