Not to sound facetious, but it doesn't get any easier than: print $token->as_is; in TokeParser and print $tree->as_HTML; in TreeBuilder to put it back into HTML form. Start with the right parser, an HTML specific one, and get better results. Remember HTML is not as rigid in it's formatting as XML which makes it flexible but a real pain to parse at times. Using a specialized parser for HTML has many benefits.
