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). If convert_charrefs is True the character references are converted automatically to the corresponding Unicode character (and self.handle_data() is no longer split in chunks), otherwise they are passed by calling self.handle_entityref() or self.handle_charref() with the string containing respectively the named or numeric reference as the argument. )ZscriptZstyle)Ztextarea�titleT)�convert_charrefsc C s || _ | �� dS )z�Initialize and reset this instance.

If enabled, "<[CDATA[" starts a CDATA section which ends with "]]>". If disabled, "<[CDATA[" starts a bogus comments which ends with ">". This method is not called by default. Its purpose is to be called in custom handle_starttag() and handle_endtag() methods, with value that depends on the adjusted current node.
