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.

5.0 out of 5 stars Written by an expert for the wannabes., October 11, 2004
This book is destined to be the prefered reference. It is well written in great depth and detail. You will however almost definitely want the XSLT 2.0 by the same author if you are new to this area as the examples in this book are more extensive with case studies, as opposed to the code snippets you'll find in here.

The book is not a tutorial, but instead aims at complete and detailed coverage and describing the differences between 1.0 and 2.0.

3.0 out of 5 stars Complete and authoritative reference, terrible format, August 1, 2007
By Timothy W. Crews (Chandler, AZ USA) - See all my reviews
(REAL NAME)   
I have never had a question about XPath that wasn't answered by this book. I appreciate having an authoritative reference written by someone who was deeply involved in the development of the standard.

However, this book (and its companion XSLT reference) is perhaps the worst-formatted reference book I have ever seen. Much of the book consists of an alphabetical reference of XPath functions. Unfortunately, the page headers and footers only contain page numbers and chapter titles. They do not contain the name of the function that is described on that page. So you can't just riff through the pages watching for your function to appear in the footer.

There is a heading for each function name, but the font used for the sub-headings are as large as (if not larger than) the major headings. There are no page breaks between functions. So you can't even visually scan the pages looking for your functions.

Finally, the table of contents consists largely of function names on the left, with page numbers on the right, separated by about five inches. But there are no dot leaders between them. So, even when you resort to using the table of contents to find the section you need, you have to use a ruler to find the page number.

4.0 out of 5 stars The basics, clear and there, January 23, 2006
By M. P. Wilson "Mark" (Winchester, VA USA) - See all my reviews
(REAL NAME)   
After stumbling around trying to a handle on XSLT, I finally realized that a big chunk was not being explained within the XSLT books. Most of the XSLT books bring XPath statements out of hat like a magician's rabbit -- there is no way one can figure out what to do in any given situation. Thanks to this book, what was mystery meat is now clear as a bell. In the first nine pages, a dozen questions were answered. I don't see how you can do serious XPath and XSLT without this book in hand.
