in reply to Seeking Xml::XPath tutorials
Your starting point: XML::XPath's documentation. Understanding XPath itself couldn't hurt; Zvon has many excellent tutorials.
* Update: 2006-03-11 Like Zvon, deepX has a good collection of "Quick References" on XML-related technologies such as XPath, XSD, XSL and XSLT (and even CSS and MySQL!).
