如何将xml文件传递给lxml进行解析？
我正在尝试使用 lxml 解析 xml 文件。 xml.etree 允许我简单地将文件名作为参数传递给 parse 函数，因此我尝试对 lxml 执行相同的操作。
我的代码：
from lxml import etree
from lxml import objectify
file = "C:\Projects\python\cb.xml"
tree = etree.parse(file)
但我收到错误：
Traceback (most recent call last):
File "cb.py", line 5, in <module>
tree = etree.parse(file)
File "lxml.etree.pyx", line 2698, in lxml.etree.parse (src/lxml/lxml.etree.c:4
9590)

我做错了什么？
I'm trying to parse an xml file using lxml. xml.etree allowed me to simply pass the file name as a parameter to the parse function, so I attempted to do the same with lxml.
My code:
from lxml import etree
from lxml import objectify
file = "C:\Projects\python\cb.xml"
tree = etree.parse(file)
but I get the error:
Traceback (most recent call last):
File "cb.py", line 5, in <module>
tree = etree.parse(file)
File "lxml.etree.pyx", line 2698, in lxml.etree.parse (src/lxml/lxml.etree.c:4

你做错的是（1）没有检查在同一个文件上使用
xml.etree是否得到了相同的结果（2）没有读取错误消息，这表明第2行中有语法错误文件的任何文件打开问题的下游What you are doing wrong is (1) not checking whether you got the same outcome by using
xml.etreeon the same file (2) not reading the error message, which indicates a syntax error in line 2 of the file, way down stream from any file-opening issue今天早上我偶然发现了一条类似的错误消息，对我来说答案是格式错误的 DTD。在我的 DTD 中，有一个属性定义，其默认值没有用引号引起来 - 一旦我更改了它，错误就不再发生。
I stumbled across a similar error message this morning, and for me the answer was a malformed DTD. In my DTD, there was an Attribute definition with a default value that was not enclosed in quotes - as soon as I changed that, the error didn't happen anymore.
您的 XML 标记 中存在语法错误。你没有做错任何事。
You have a syntax error in your XML Markup. You aren't doing anything wrong.
lxml 允许您通过使用 recover=True
虽然这并不理想，但我使用它来加载 xml 以进行 schema/dtd/schematron 验证。
lxml allows you load a broken xml by creating a parser instance with recover=True
While this is not ideal, I use this to load an xml for schema/dtd/schematron validation.
