提取成一个字典

下面写的不好使：
from xml import sax
class TestHandler(sax.ContentHandler): # 定义自己的handler类，继承sax.ContentHandler
def __init__(self):
sax.ContentHandler.__init__(self) # 父类和子类都需要初始化（做一些变量的赋值操作等）
self._content =""
def startElement(self, name, attrs): # 遇到<tag>标签时候会执行的方法，这里的name，attrs不用自己传值的（这里其实是重写）
self._tag = name
if name == "Config":
print("==================")
def endElement(self, name):
if name == "Config":
print(self._content)
else:
pass
def characters(self, content): # 获取标签内容
self._content=content
if __name__ == "__main__":
handler = TestHandler() # 自定义类实例化成对象
sax.parse("test.xml", handler) # 解析xml文件 展开
