This package is a little piece of Google's Chromium DevTools project which modified to make it work on JSDOM.

The DOMPath is responsible for generating a selector given an element in a particular DOM hierarchy. Its methods can be accessed via the following menu:
Open DevTools -> Navigate to Elements tab -> Right click on selected Element -> Copy
