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']
>没有编码(‘utf-8’):
etree.fromstring(items [0])输出:
ValueError

不知道解析这个xml ..
解决方法:
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)
看到@ Lea在问题中的评论后更新:
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'))
