Another way of parsing: what if we have some 'types' of entrieS? We look for type_field_EVENT (or for field_EVENT).

parse_target2.py

class ParseTarget(object):
    TYPES = frozenset(('tire', 'disc', 'oil', 'acc', 'additional',))


    def __init__(self):
        self.current_tag = None
        self.current_type = None

        self._depth = 0

    def execute_method(self, event, *args, **kwargs):
        if self.current_tag is None or self.current_type is None:
            return

        big_method_name = '_'.join((self.current_type, self.current_tag, event,))  # tire_vendor_start
        short_method_name = '_'.join((self.current_tag, event,))  # vendor_start

        method = getattr(self, big_method_name, None) or getattr(self, short_method_name, None)

        if method is not None:
            return method(*args, **kwargs)


    def start(self, tag, attrib):
        if self._depth == 1 and tag in self.TYPES:
            self.current_type = tag

        self._depth += 1

        self.current_tag = tag

        self.execute_method('start', attrib)


    def end(self, tag):
        self.execute_method('stop')

        self.current_tag = None
        self._depth -= 1


    def close(self):
        self.current_tag = None


    def data(self, data):
        if self.current_tag is None:
            return

        self.execute_method('data', data)
