Here is the sitemap you're looking for. The only issue I have is with pagenination. The a.rightarrow calls a javascript function and I'm not sure how to make that work @iconoclast?
Yeah for some reason 'artificial' click won't work on this page (JavaScript was coded with errors on it), but we can go around it and imitate 'user' click using get(0) method inside Tampermonkey extension.
Please download it, and import script i've made for you below (it will automatically open all entries once you open a page).
// ==UserScript==

(function() {
'use strict';
$(document).ready(function(){
$('#expandAll').get(0).click();
});
// Your code here...
})();
