简化下： class YHWeatherSaxHandler(object): def init(self): self.data = { 'forecast': [] }

def start_element(self, name, attrs):
    if name == 'yweather:location':
        self.data['city'] = attrs['city']

    elif name == 'yweather:forecast':
        self.data['forecast'].append({
            'date': attrs['date'],
            'high': attrs['high'],
            'low' : attrs['low']
        })

def parseXml(xml_str):

#print(xml_str)

handler = YHWeatherSaxHandler()
parser = ParserCreate()
parser.StartElementHandler = handler.start_element

parser.Parse(xml_str)
return handler.data
