Actually, saving the content of the pages via browser has apparently some disadvantages, since - at least for firefox - the browser rewrites some parts - and fixes some invalid markup.
Therefore, i've implemented some support to capture the server output optionally [1] and fixed with that tool a few more validation problems of the admin pages. The problem with the site-map page is actually a nasty one, since the old code implemented a form starting in one table cell and ending in another one, which is invalid HTML. The fixed version [2] does not look exactly as before, but i think it is still sufficiently easy to understand. Other options would be to start the form before a <tr>, but i have no idea to achieve this with the list template.
