It never recovers from the error. HTMLParser has an internal buffer and buffer pointer that is never advanced when an error is detected; each time you call feed() it tries to parse the remaining data and gets the same error again. Take a look at HTMLParser.goahead() in Lib/HTMLParser.py if you are interested in the details.
IIRC HTMLParser is not noted for handling badly formed HTML. Beautiful Soup, ElementTidy, or HTML Scraper might be a better choice depending on what you are trying to do.
