Building a XML DOM tree

I need help developing javascript code that will run through a webpage and recreate the DOM tree structure of the page in text form. I've been told to use a recursive function. I don't really know any javascript.

At each node I need the node name and the node type.

Any help?

 

here is an article with example how to recursive traverse DOM via jQuery:

I hope it helps.
