So, are you really interested in broken *links* (as in a GET does not
return a 200 result code) or broken HTML? I have done the former via
AJAX (jQuery sends links to a backend rails action, and if it is
broken changes the class of the link to display a red background). The
latter may be able to be done with libxml, which reports the character
position of broken input.
