我没用正则表达式，用了beautifulsoup
代码比较简易
import urllib2
from bs4 import BeautifulSoup
url =
user_agent = 'Mozilla/5.0 (Windows NT 6.1)'
headers = {'User-agent' : user_agent}
request = urllib2.Request(url,headers= headers)
response = urllib2.urlopen(request)
cat_img = response.read().decode('utf-8')
bs0bj = BeautifulSoup(cat_img,"html.parser")
namelist = bs0bj.findAll('div', "content")
for name in namelist:
print(name.string)
