Watt A. XPath essentials

Wiley Publishing, 2002. - 544 pages. 1 edition. ISBN-10: 0471205486, ISBN-13: 978-0471205487.This book is a learn-by-doing book. It is for anybody who needs to start using XPath
today. Throughout the chapters of this book, you will be shown example after example
of working code that uses XPath. As you work through the text and the examples, I
think you will find code that you can adapt or extend to your own needs and purposes.Because the primary use of XPath at the time of writing is with XSLT, many of the examples in this book are focused on transforming XML documents either to HTML/XHTML
or to other XML formats.If you have a background in HTML, XHTML, XML, or XSLT, that will help move you
along faster. If you don’t have any markup language background, don’t worry. The introductory material in Chapter 1 will give you a start with XML and XSLT that will give
you a framework for later reading. If you have problems later in this book you may
want to refer back to Chapter 1 or its examples to review the necessary foundational
knowledge.My aim in presenting many examples is to get you on your own feet using XPath as
quickly as possible.
