If this is a one time task, write a script to iterate over the html files, and collect the traceback info from those that throw a 'mismatched tag' error. Based on your example below, it appears to contain the line number. You'd only get one error per file per run, but you can run it until there are no errors remaining. I hope that makes sense.
