This book introduces the various parts of the construction of a regular expression pattern, explains what they mean, and walks you through working examples showing how they work and why they do what they do. By working through the examples, you will build your understanding of how to make regular expressions do what you want them to do and avoid creating regular expressions that don t meet your intentions. Beginning chapters introduce regular expressions and show you a method you can use to break down a text manipulation problem into component parts so that you can make an intelligent choice about constructing a regular expression pattern that matches what you want it to match and avoids matching unwanted text. To solve more complex problems, you should set out a problem definition and progressively refine it to express it in English in a way that corresponds to a regular expression pattern that does what you want it to do. The second part of the book devotes a chapter to each of several technologies available on the Windows platform. You are shown how to use each tool or language with regular expressions (for example, how to do a lookahead in Perl or create a named variable in C#). Regular expressions can be useful in applications such as Microsoft Word, OpenOffice.org Writer, Microsoft Excel, and Microsoft Access. A chapter is devoted to each. In addition, tools such as the little–known Windows findstr utility and the commercial PowerGrep tool each have a chapter showing how they can be used to solve text manipulation tasks that span multiple files. The use of regular expressions in the MySQL and Microsoft SQL Server databases are also demonstrated. Several programming languages have a chapter describing the metacharacters available for use in those languages together with demonstrations of how the objects or classes of that language can be used with regular expressions. The languages covered are VBScript, Javascript, Visual Basic .NET, C#, PHP, Java, and Perl. XML is used increasingly to store textual data. The W3C XML Schema definition language can use regular expressions to automatically validate data in an XML document. W3C XML Schema has a chapter demonstrating how regular expressions can be used with the xs:pattern element. Chapters 1 through 10 describe the component parts of regular expression patterns and show you what they do and how they can be used with a variety of text manipulation tools and languages. You should work through these chapters in order and build up your understanding of regular expressions. The book then devotes a chapter to each of several text manipulation tools and programming languages. These chapters assume knowledge from Chapters 1 through 10, but you can dip into the tool–specific and language–specific chapters in any order you want.

Regular Expressions are a text processing technology supported by all major databases, scripting languages, and programming languagesThis topic is important because: Developers can use regular expressions to validate input in for security purposes in applications, validate input before it is stored in a database, or to find/edit/modify specific bits of text in large batches of text files, like web pages. Wrox's Beginning Regular Expressions takes an example oriented approach for beginners, with chapters on using regular expressions with popular Windows platform databases, cross platform scripting languages, and programming languages· Regular Expression Tools and an Approach to Using Them· Simple Regular Expressions· Metacharacters and Modifiers· Character Classes· String, Line, and Word Boundaries· Parentheses in Regular Expressions· Lookahead and Lookbehind· Sensitivity and Specificity of Regular Expressions· Documenting and Debugging Regular Expressions· Regular Expressions in Microsoft Word· Regular Expressions in StarOffice/OpenOffice.org Writer· Regular Expressions Using findstr· PowerGREP· Wildcards in Microsoft Excel· Regular Expression Functionality in SQL Server 2000· Using Regular Expressions with MySQL· Regular Expressions and Microsoft Access· Regular Expressions in JScript and JavaScript· Regular Expressions and VBScript· Visual Basic .NET and Regular Expressions· C# and Regular Expressions· PHP and Regular Expressions· Regular Expressions in W3C XML Schema· Regular Expressions in Java· Regular Expressions in Perl

Support for regular expressions in SQL and PL/SQL is one of the most exciting features of Oracle Database 10G. Oracle has long supported the ANSI-standard LIKE predicate for rudimentary pattern matching, but regular expressions take pattern matching to a new level. They provide a powerful way to select data that matches a pattern, as well as to manipulate, rearrange, and change that data.This concise pocket guide is part tutorial and part quick-reference. It's suitable for those who have never used regular expressions before, as well as those who have experience with Perl and other languages supporting regular expressions. The book describes Oracle Database 10G's support for regular expressions, including globalization support and differences between Perl's syntax and the POSIX syntax supported by Oracle 10G. It also provides a comprehensive reference, including examples, to all supported regular expression operators, functions, and error messages.O'Reilly's Pocket References have become a favorite among developers and database administrators everywhere. By providing a wealth of important details in a concise, well-organized format, these handy books deliver just what you need to complete the task at hand. Whether you're using regular expressions for the first time or applying your skills from other languages to the latest version of Oracle, the Oracle Regular Expressions Pocket Reference is the book to have close by.
