Feed new data to the Parser.HTML object. This will start a scan
and may result in callbacks. Note that it's possible that all data
fed isn't processed - to do that, call finish() .
If the function is called without arguments, no data is fed, but
the parser is run. If the string argument is followed by a
0
, ->feed(s,0);
, the string is fed, but the parser
isn't run.
