Wanted: minimal XPath sample

Xalan was supposed to contain an XPATH example that could run with only standard jar files. Unfortunately, I can find no such example in the latest xalan.

Can someone convert the example below (or provide a similar example) so it will run without putting xalan in the class path?
Thanks,
Siegfried

Make sure you are using Java 5 or later. Start by replacing "import org.apache.xpath.XPathAPI;" with "import javax.xml.xpath.*". Then replace the beginning of the XPath code like this:I will let you do the rest of the changes and fix whatever I didn't do quite right there.
