Python使用文件中的内容重命名工作目录中该文件类型的所有文件

最初，我需要帮助读取目录中的文件名。我能找到我的答案，但有更多的问题。我试图在文件夹结构中标识的文件中包含xml。在识别这些文件之后，我需要一种方法来解析xml中的元数据。从xml中取出元数据后，我需要保存一个共享相同名称但具有不同文件扩展名的文件。我想保留文件名，并从xml中包含我想要的两个标志。我希望在重命名时将文件从源文件夹移到新文件夹中。这是最终结果，除了我遇到的一些其他障碍外，还包含了我问题的答案。我感谢人们的反馈，我知道我的问题和最初的要求都不好。这是我第一次在这个网站上发帖。再次感谢，希望这能帮助其他人

这是我的第一个Python程序，我想用它做更多的事情。如果我做了一些可以修改以提高效率的事情，我会很感激这些提示或指针。

将其加载到DOM中，并提取所需节点的值。 将该值保存在变量中。关闭要重命名的文件。使用变量中存储的值重命名文件

抱歉，这只是伪代码，但所有步骤在许多地方都有很好的文档记录

没有你的代码和你遇到的问题的细节，你很难回答你的问题。
