Python 脚本生成和 XML 使用 if 条件错误
Python script to generate and XML using if condition Error
我正在制作 python 脚本来创建 XML 文档并将文件中的字母数字添加到 XML。在将文件中的数据添加到 XML 文档之前，如果数据符合条件（如果长度等于 32、40 或 64），我会添加 if 条件。否则，我不会将该数据添加到 XML。我还实现了将数据添加到 XML 的输入。我尝试编写 XML 并阅读它，但存在与 lxml synatx 错误相关的错误。
我试着研究如何写作 XML。我只是看不出我的代码和教程有什么区别。

问题出在你给出的条件上
if length != 32 or length != 40 or length != 64:
在这里，无论您为长度提供什么输入或值，由于使用了 'or'，此条件始终为真。无论长度是多少，长度都不能同时为32、40、64。
因此 data.xml 文件根本没有写入数据（假设 data.xml 文件开始时是空的）。
因此它找不到任何“<”标签（根据错误消息）。
推荐的解决方案是使用相反的方法，即
if length==32 or length==40 or length==64:
#your code to write to data.xml file
else:
#your code for invalid alphanumeric
或使用 'and' 条件
if length!=32 and length!=40 and length!=64:
#your code for invalid alphanumeric
else:
#your code to write to data.xml file
希望对您有所帮助！！
看这里 - 我做了一些重写，但我希望我保持逻辑
