在Python中读取多个XML:ParseError:格式不正确（无效令牌）
我必须阅读近千个XML文件，并在其中的X坐标和Y坐标上执行聚类。为此，我打开它们中的每一个，运行几个循环来获取坐标，并将它们附加到数据帧中。但是，我得到了下面的常见错误。在讨论了这个问题的其他解决方案之后，恐怕将编码更改为UTF-8并不能解决问题在Python中读取多个XML:ParseError:格式不正确（无效令牌）,python,xml,pandas,xml-parsing,Python,Xml,Pandas,Xml Parsing,我必须阅读近千个XML文件，并在其中的X坐标和Y坐标上执行聚类。为此，我打开它们中的每一个，运行几个循环来获取坐标，并将它们附加到数据帧中。但是，我得到了下面的常见错误。在讨论了这个问题的其他解决方案之后，恐怕将编码更改为UTF-8并不能解决问题 ParseError: not well-formed (invalid token): line 1, column 1 其中一个XML文件如下所示。坐标标记位于交叉标记标记内 <?xml version="1.0" encoding="ut

我仍然是Python的新手，因此如果我的代码有任何其他问题，或者为了能够运行数据帧（一次10个坐标）并给出结果，可以提供更好的解决方案，我将非常感激。解决方案似乎是添加
encoding=“utf-8”语句，如带有open（filename'r'，encoding=“utf-8”）的中的当前文件：
。只有这样解析器才能工作。显然，您应该更新代码以识别错误的XML文件，并具体查看它。我不明白您的意思。所有XML文件（将近一千个）的结构都是相同的，文件夹中没有非XML文件。所以我看不出文件的结构有什么问题，但你有一个问题。（我们不能相信您的评估，即当您同时告诉我们其中一个文件失败时，您的所有文件都是相同的。）为了我们和您的利益，请将问题的搜索空间减少到显示问题的最小数据和代码。创建并发布一个——注释最小且可复制（在我们这边）。
