What's in This Book?
This book is intended to cover all of XPath 1.0 and the current working draft of XPath 2.0. XPath 1.0 is an established recommendation from the World Wide Web Consortium (W3C), and as of this writing, XPath 2.0 is in W3C working draft form. We're going to work from the most basic to the fairly advanced in both these specifications.
The first half of this book is dedicated to XPath 1.0, and the second to XPath 2.0. You won't need any programming skills to work with XPath in this bookyou will, however, need a basic knowledge of HTML and XML.
Here's an overview of some of the topics we'll see in this book:
As you can see, we've got a great deal of XPath coverage planned for this bookboth XPath 1.0 and 2.0.
