OK, that wasn't clear from your first post.
You're not going to be able to correct all of the errors easily, but the
suggestion of using DOM to help is a good one. It will help a lot. But
you don't want to correct the errors - how do you know the correction
itself is correct? You want to just give the user an error message.
However, I'd take a different approach - I'd put in a preview button
(possibly required) which brings up the prospective page in a new window
to let the user verify it looks ok.
