Comprehensive Regular Expression Recipes

As its name implies, Comprehensive Regular Expression Recipes - A Practical Cookbook provides solutions to solve many practical problems. Because such solutions are not possible without reference to the language elements, the first part of the book introduces the regex concepts. The second part is the "cookbook" with the "recipes". Most recipes start fairly basic, but still solve practical problems, and are successively refined. To simplify understanding, most recipes are explained graphically and augmented with diagrams when necessary. More advanced concepts, such as bounds, Unicode, lookarounds and atomic groups, are handled.

Covers the basics of regular expressions along with recipes for common tasks using C#, Java, JavaScript, Perl, PHP, Python, Ruby, and VB NET.

Take the guesswork out of using regular expressions. With more than 140 practical recipes, this cookbook provides everything you need to solve a wide range of real-world problems. Novices will learn basic skills and tools, and programmers and experienced users will find a wealth of detail. Each recipe provides samples you can use right away. This revised edition covers the regular expression flavors used by C#, Java, JavaScript, Perl, PHP, Python, Ruby, and VB.NET. You’ll learn powerful new tricks, avoid flavor-specific gotchas, and save valuable time with this huge library of practical solutions. Learn regular expressions basics through a detailed tutorial Use code listings to implement regular expressions with your language of choice Understand how regular expressions differ from language to language Handle common user input with recipes for validation and formatting Find and manipulate words, special characters, and lines of text Detect integers, floating-point numbers, and other numerical formats Parse source code and process log files Use regular expressions in URLs, paths, and IP addresses Manipulate HTML, XML, and data exchange formats Discover little-known regular expression tricks and techniques

*Discusses regular expressions in quick, easy manner (Friedl book is exhaustive, and other two books are superficial) *Teaches by example without exhaustive syntax explanation *Covers the major open source languages

The aim of Practical Usage of Regular Expressions is to provide a graduated introduction to regular expressions (regexes) and to show many practical examples of their use. Although, for simplicity, this book discusses the Microsoft® .NET®-based flavour (implementation), the concepts apply (at least at the introductory and intermediate level) to most regex flavours. Even complex constructs are explained clearly with schematic diagrams and appropriate examples. The clear structure, many illustrative examples, useful regexes and syntax summary make the book ideal as reference. The comprehensive worked example gives beginners a painless introduction to regexes and explains all needed concepts, except for the most advanced applications. The reader exercises (with solutions) also make the book ideal as tutorial. Although concise, the book provides entry- and intermediate-level regex users with detailed reference material. More than 100 practical examples augment the text content.This book is based on my more comprehensive book of the same Regex series but devoid of the translation environment-specific content.

* Only book dealing with regular expressions for Windows developers in a concise manner * Teaches beginners by example, without bogging them down in syntactical explanations; also an ideal reference for experienced developers/ programmers * Covers all of the major Windows development languages

Introduces regular expressions and how they are used, discussing topics including metacharacters, nomenclature, matching and modifying text, expression processing, benchmarking, optimizations, and loops.
