用正则表达式完成xpath的功能（强大的正则表达式） 

1 url = 'http://money.163.com/special/pinglun'
2 response = requests.get(url)
3 # regex = re.compile('''<li><span class="article"><a href="([^"]+?)">([^<]?)</a></span><span class="atimef12px">\(([^\)]+?)\)</span></li>''')
4 res = re.findall(r'<a href="([^"]+?)" title="([^"]+?)">',response.text)
5 for l in res:
6     print(l[0])
7     print(l[1])
