，我想找到<a> and </a>标签

<a href = "link">This part here</a>

而且之间的文本，我需要确保“这一部分在这里“不包含任何标签。

我做什么，

headers = soup.findAll('div','compTitle') 
for header in headers: 
    if header is not None: 
     t = header.a.string.encode('utf-8') 
     print t

所以，我预计产量

Jaguar: Luxury Cars &amp; Sports Cars | Jaguar USA 
Jaguar - How Alive Are You? 
Jaguar International - Market selector page 
Jaguars, Jaguar Pictures, Jaguar Facts - National Geographic

但我得到一个错误，指出

AttributeError: 'NoneType' object has no attribute 'encode'

尝试这样即可：

>>> for x in soup.find_all('div', 'compTitle'): 
...  print x.a.text 
... 
Jaguar: Luxury Cars & Sports Cars | Jaguar USA 
Jaguar - How Alive Are You? 
Jaguar International - Market selector page 
Jaguars, Jaguar Pictures, Jaguar Facts - National Geographic

那么究竟是什么文字和字符串中物体之间的区别？ – ronilp 2015-04-05 03:53:27

检查这一个http://stackoverflow.com/questions/25327693/difference-between-string-and-text-beautifulsoup – Hackaholic 2015-04-05 03:58:39

使用text代替string，即改变

t = header.a.string.encode('utf-8')

到

t = header.a.text.encode('utf-8')
