用python的抓取内容后，想发布到wordpress，但是总是报错，不知道是什么原因，如果手动指定title和content字符串的话是可以发布成功的，请大神赐教，我是新手小白。
import requests

r = requests.get(url).text
r = re.sub('<','<', r)
r = re.sub('>','>', r)
r = re.sub('=','=', r)
r = re.sub('"','"', r)
soup = BeautifulSoup(r,'lxml')
title = soup.title.string
result = re.search(r'<div>.*</div>', r).group()
wp = Client('http://www.pl.com/xmlrpc.php', 'pl', 'BEIJ')
"""
发表博文

post = WordPressPost()
post.title = title
post.content = result
post.post_status = 'publish'
wp.call(NewPost(post))
