Question

假设我的文字是

   <div class="compTitle"><h3 class="title"><a href="http://www.jaguarusa.com/index.html" target="_blank" data-80a="5520a3b52c6fe"><b></b><b>Jaguar</b>: Luxury Cars &amp; Sports Cars | <b></b><b>Jaguar</b> USA</a></h3> <div><span class=" fz-15px fw-m fc-12th wr-bw">www.<b></b><b>jaguar</b>usa.com</span><a class="tri fc-3rd fz-2xs ml-10" href="http://cc.bingj.com/cache.aspx?q=jaguar&amp;d=4967534815872005&amp;mkt=en-US&amp;setlang=en-US&amp;w=EK-x56coxxfS-VYEa33LnCSKRL4yj3aK" target="_blank" data-80a="5520a3b52c7ec">Cached</a></div></div>

我想找到 <a> and </a> 标签之间的文本

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

此外，我需要确保 "This part here" 不包含任何标签。

我正在做的是，

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，我的预期输出是

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

但是我收到一条错误消息说

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

Answer 1

然后像这样尝试：

>>> 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

Answer 2

使用text代替string，即改变

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

到

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