You'd probably write a function that called itself to parse something like this. Unfortunately, I am not a recursion expert. You can read up on it though: http://www.freenetpages.co.uk/hp/alan.gauld/tutrecur.htm http://pythonjournal.cognizor.com/pyj2.2/RecursionByAJChung.html I haven't used Beautiful Soup, but I think you can use lxml or ElementTree to get a tree object of the XML and then just iterate over the tree.
