解析XML文件时：

from lxml import etree

with open('cortex_full.xml', 'r') as infile:
    root = etree.parse(infile)

我得到UnicodeDecodeError以下。不过，这只发生在我的 Mac 上 - 如果我在工作 PC 上使用相同的脚本解析相同的文件，一切正常。

File "/Users/Desktop/CPET/xml_test2.py", line 5, in <module>
    root = etree.parse(infile)

    return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 783: ordinal not in range(128)

考虑到此处的线程数，这似乎很常见，但是建议的修复程序似乎都不适用于此实例。让它工作的任何想法？完整XML文件在这里

发布对我有用的答案以供将来参考。归功于@Burhan Khalid 的答案。

utf-8打开xml文件时需要设置编码。

with open('cortex_full.xml', 'r', encoding='utf-8') as infile:
