Finding out what line number an element in the dom occurs on in Javascript?

Though I've never heard of this but, is it possible to retrieve a node from the DOM using JS, and then find out on what line of the file that node occurred on?

I'm open to anything, alternative browsers plugins/add-ons etc...it doesn't need to be cross-browser per say.

I would assume that this would be possible somehow considering that some JS debuggers are capable of finding the line number within a script tag, but I'm not entirely sure.
