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.
