In a dom, is there a way to get elements by the path?
e.g. getElementsByTagName("level1/level2/level3")

Many thanks.

Sunny,

Thanks for your quick response. Where is this XPathAPI located? I checked the xalan.jar, and couldn't find the class. Any idea?

The full name of the class is org.apache.xpath.XPathAPI. It's located in xalan*.jar (available at http://xml.apache.org/ . This class contains a set of static methods that will parse and execute an XPath expression.
