Python 解析XML lxml我应该跳过或删除注释阻塞解析吗

我有一个XML文件，第一行以

<!--

该文件在使用Objectify执行转储根目录时有效，但运行完美，失败的是etree

这是一个相当大的文件XML的第一个元素的注释和选定的剪贴

取消版权声明。在python 3 unicode环境中，xml文档中有一个扩展ascii字符（版权符号），没有指定编码，也没有xml声明标记。我无法想象好事会发生。删除版权符号，并查看您的问题是否消失。

如果您确实想删除注释，但可以传递

parser=et.HTMLParser（Remove_comments=True）

或

parser=et.XMLParser（Remove_comments=True），注释应该不会对etree造成任何问题，并且不会在我使用python2或python3的计算机上出现)

根据您的需要：

import  lxml.etree as et

x = et.parse("test.xml", parser=et.HTMLParser(remove_comments=True))
print(et.tostring(x))

---

xml解析器应该正确识别文档元素标记前面的注释节点。。。这可能是lxml中的一个错误……您是否可以包括加载文件时使用的代码，以及XML文件本身是否可以再包含几行代码？您是否确实知道您的XML是有效的？正确关闭的评论不应该是问题。退房
