问题描述
我正在使用 Python 处理这个项目，其中第一步涉及解析 xml 文件中的一些数据。但是，为此任务生成的 xml 文件创建了太多属性，需要以某种方式合并数据。
无论如何，我认为我需要做的第一件事是让递归函数工作。我一直在使用这个网站 (https://www.datacamp.com/community/tutorials/python-xml-elementtree) 作为指南以及其他各种谷歌搜索来编辑 xml 文件。但是，findall 函数在我的脚本中的工作方式似乎与互联网上每个人的建议不同。所以我想知道我哪里出错了。
这里是xml：
#define BOOST_TEST_MODULE test module name
#include <boost/test/included/unit_test.hpp>
现在，使用 ElementTree，我可以按照您的预期浏览 xml 元素，例如。

返回结果：

print(child.tag,child.attrib)
但是，当我尝试执行递归函数时，例如

... 脚本将正常运行，但不会返回任何结果。我有点困惑，因为我看不出我在做什么与教程链接告诉我做什么有什么不同，或者与此相关的各种其他互联网资源。
我希望你们互联网天才能帮帮我，谢谢！
