lxml无法解析xml（其他编码是否为utf-8）[python]

My code:

我的代码：

import re
import requests
from lxml import etree

url = 'http://weixin.sogou.com/gzhjs?openid=oIWsFt__d2wSBKMfQtkFfeVq_u8I&ext=2JjmXOu9jMsFW8Sh4E_XmC0DOkcPpGX18Zm8qPG7F0L5ffrupfFtkDqSOm47Bv9U'

r = requests.get(url)

items = r.json()['items']

without encode('utf-8'):
没有编码（'utf-8'）：

etree.fromstring(items[0]) output:

etree.fromstring（items [0]）输出：

ValueError

1 个解决方案

As a workaround, you can remove encoding attribute before pass the string to etree.fromstring:

作为解决方法，您可以在将字符串传递给etree.fromstring之前删除编码属性：

xml = re.sub(r'\bencoding="[-\w]+"', '', items[0], count=1)
root = etree.fromstring(xml)

UPDATE after seeing @Lea's comment in the question:

在看到@Lea在问题中的评论后更新：

Specify parser with explicit encoding:

使用显式编码指定解析器：

xml = r.json()['items'].encode('utf-8')
root = etree.fromstring(xml, parser=etree.XMLParser(encoding='utf-8'))
