logging with filters

Just implement a subclass of logging.Filter: http://docs.python.org/library/logging.html#filter-objects. It will have one method, filter(record), that examines the log record and returns True to log it or False to discard it. Then you can install the filter on either a Logger or a Handler by calling its addFilter(filter) method.


class NoParsingFilter(logging.Filter):
    def filter(self, record):
        return not record.getMessage().startswith('parsing')


Or something like that, anyway.
