Extending the library to include element position in text

This is not a bug but a question. I want to use your library for annotating position of HTML elements from BeautifulSoup and Selenium within the generated text. How do I go about integrating BeautifulSoup into your library? Any pointers would be appreciated.

To illustrate what I am trying to achieve better, if your library only has text content inside the nodes, I want to prefix the text with x and y coordinates of the node.
