can any one help me??

I have an html document. i need the java code for the dom tree representation of that document. if i got the dom tree representation i can proceed with the next step of finding the path of each node

please help me/...

Have you considered using the following classes to manage DOM manipulation with Java?

• DocumentBuilderFactory
• DocumentBuilder
• Document

They are in the javax.xml.parsers package.

Can u help me to find get the path of each node as a String?
