获取每个页面的元素，并写入json

获取每个页面的元素，并写入json

想法：如何去记住每个页面的元素，如何实现不同页面的导航，如何从主页面遍历每一个页面的每一个元素
1.创建数据结构存储
2.树状图正好是我们想要的结构体：创建树状图结构体
3.记录每个页面的元素

    # 获取设备实例
    id_xpath, class_xpath, text_xpath, class_and_text_xpath = "", "", "", ""
    mapping = {}
    device = u2.connect()
    hierarchy = device.dump_hierarchy()
    root = ET.fromstring(hierarchy)
    # 遍历视图层次结构并打印视图信息
    for element in root.iter():
        # print( element.attrib)
        # 获取元素的文本内容
        text = element.get('text')
        # 获取元素的 resource-id 属性
        resource_id = element.get('resource-id')
