Usage: p = HTMLParser() p.feed(data) ... p.close() Start tags are handled by calling self.handle_starttag() or self.handle_startendtag(); end tags by self.handle_endtag(). The data between tags is passed from the parser to the derived class by calling self.handle_data() with the data as argument (the data may be split up in arbitrary chunks). Entity references are passed by calling self.handle_entityref() with the entity reference as the argument. Numeric character references are passed to self.handle_charref() with the string containing the reference as the argument. t scriptt stylec C s | j � d S( s# Initialize and reset this instance.N( t reset( R ( ( s" /usr/lib64/python2.7/HTMLParser.pyR b s c C s8 d | _ d | _ t | _ d | _ t j j | � d S( s1 Reset this instance.
