 def read_xml():
    # 多测师_王sir
    # parse() 获取 DOM 对象 
    dom = minidom.parse('file.xml')
    # 获取根节点
    root = dom.documentElement
    # 通过 dom 对象或根元素，再根据标签名获取元素节点，是个列表
    tag = root.getElementsByTagName("string")
    # 读取标签对之间的数据，标签从上到下按照下标从 0 开始
    print(tag[2].firstChild.data)

if __name__ == '__main__':
    read_xml()

运行结果：黑龙江
