XPath Basics - The Next Step (Page 9 of 9 )
And that just about concludes this little tour of XPath. In this article, you learnt a little about the history, need and rationale for XPath, together with an in-depth look at the various components of an XPath location reference. You also found out how to use XPath operators to build complex expressions, and XPath functions to perform simple processing tasks.
I hope you found this tutorial useful and informative, and that the material discussed here offers you some assistance in navigating the treacherous rapids of XML and XSL. You should now pop open your favourite XML document and begin playing with XPath to better understand how it works - the more you experiment with it, the easier it will become and, before long, you'll be constructing location paths without thinking twice.
