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 regular expressions, 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.
