XPath Kick Start : Navigating XML with XPath 1.0 and 2.0 Steven Holzner

XPath is to XML as SQL is to databases: XML applications need XPath to locate specific data within an XML document for further processing with other XML applications such as XSLT, XQuery, XPointer, XLink and DOM level 3. With XPath, these applications offer developers a full toolkit for transforming, linking, and searching XML data. Developers need to understand XPath to fully exploit XML in their applications, and they have few resources beyond the W3C specification. XPath Kick Start will examine every aspect of XPath in detail, including its influence on and use with these other XML standards.
