Product Description

What is this book about?

XPath 2.0 Programmer's Reference is the only authoritative reference on XPath, a sub-language within XSLT that determines which part of an XML document the XSLT transforms. Written for professional programmers who use XML every day but find the W3C XPath specifications tough to slog through, this book explains in everyday language what every construct in the language does and how to use it. It also offers background material on the design thinking behind the language, gentle criticism of the language specification when appropriate, and a diverse range of interesting examples in various application areas.

From the Back Cover

From its origins as a sublanguage of XSLT, XPath has come into its own as a key element of XML. XPath 2.0 has emerged as a robust language twice the size of its predecessor, complex and capable of standing on its own.

This substantive volume, by the editor of the W3C® XSLT 2.0 specification, is the authoritative reference on XPath 2.0. It begins by thoroughly explaining the foundations, including XML schema and the evaluation context. Building on this knowledge, it then moves through literals and function calls, basic operators, path expressions, types, and the regular expressions of three new functions that greatly boost the power of XPath 2.0.

What you will learn from this book

Top-level constructs and the lexical rules for using whitespace and comments
Basic operators for writing arithmetic and Boolean expressions
Three operators for combining the results of path expressions: union, intersect, and except
How XPath 2.0 supports sequences
Where to access a complete listing of all functions in the core function library
How to define the syntax of XPath regular expressions as used in the new functions matches(), replace(), and tokenize(), and much more

Who this book is for

This book is for experienced programmers who use XPath 2.0 and want a comprehensive understanding of it at every level. A basic knowledge of XML and Web architecture is essential.

Wrox Programmer’s References are designed to give the experienced developer straight facts on a new technology, without hype or unnecessary explanations. They deliver hard information with plenty of practical examples to help you apply new tools to your development projects today.
