The exact file to check is https://github.com/ChromeDevTools/devtools-frontend/blob/master/front_end/elements/DOMPath.js

We can traverse from the leaf to the root of the dom tree and build the path. Not only XPath, but also CSS selector.

We should also design an algorithm to search for the shortest selector, resilient selector.
