Locate specific sections of your XML documents with XPath, Part 1
XML is a data format concerned primarily with compatibility and flexibility. But as useful as XML is, it's limited without the abilities to find specific portions of a document quickly and to filter and selectively locate data within a document. XPath provides the ability to easily reference specific text, elements, and attributes within a document -- and with a fairly low learning curve. Additionally, XPath is key to many other XML vocabularies and technologies, such as XSL and XQuery. This tutorial will teach you the fundamentals of XPath, including all of its various selectors and semantics, in an example-driven and hands-on manner. 		10 Jun 2008  
 
Locate specific sections of your XML documents with XPath, Part 2
Part 1 of this tutorial gave you a foundational understanding of XPath. Using slash notation, wildcards, unions, and simple text, you learned how to locate elements and attributes anywhere within an XML document. However, sometimes you need more than just matching based on the name of a node. Predicates give you advanced and refined searching capabilities, allowing you to evaluate the values of attributes and the parent and child nodes of a targeted element. Rather than find a wider node set and refine or filter that set programmatically, you can add predicates to your XPaths to find exactly the nodes you want. 		17 Jun 2008
