A Selenium-based solution would not be as general-purpose, but for an AngularJS-based menu, something like the following would work in Selenium:. For this solution I opted to design the crawler without Selenium, which means occasionally crawling JS files to root out further links.
I tested this mainly against my own incomplete blog www. There is also a simple unit test for the ThoroughMiddleware. It utilizes a static file, html-test. To run the unit test, do. Skip to content.

MIME Multipurpose Internet Mail Extensions is a standard for formatting files to be sent over the internet so they can be viewed in a browser or email application.
