I know you could use the
def start_a ..... def end_a ..... to process the <a href=...> anchor </a> tags, but is there a default method for processing ALL tags? If I just want change some parts of the hyperlink and want to keep other parts of the HTML could I just print them out? There should be such a method. Can't find it... Thank you. |

You could subclass HTMLParser.HTMLParser and override handle_starttag and handle_endtag (also, if needed, handle_charref, handle_entityref, and last but not least handle_data -- that's assuming that while you only talk about processing _tags_ you may in fact also want to process references and text nodes... possibly handle_comment, too, btw).

If you are modifying the contents of tags I've written a simple HTML parser class called Scraper that does this. Unlike the HTMLParser in the standard library it doesn't choke so much on badly formed HTML.... It's part of approx.py my cgiproxy.... [url down] HTH Regards, Fuzzy |
