我已经解析了下面的string来美化组以从中提取数据，但是我不能得到一些数据。尝试过不同的方法。我设法找出了<a>标记之间的文本、链接和每个链接之外的文本。在

<html>
 <body>
  <p align="left">
   <font face="Arial, Helvetica, sans-serif" size="2">
    <b>
     <font size="4">
      GOVERNOR:
     </font>
    </b>
    <br/>
   </font>
   <font face="Arial, Helvetica, sans-serif" size="2">
    <a href="http://governor.alabama.gov/">
     <strong>
      Robert 
                Bentley (R)*
     </strong>
    </a>
    - Ex-Morgan County Commissioner &amp; State Correctional Officer
    <strong>
     <br/>
     <a href="http://www.facebook.com/stacy.george.3139">
      Stacy George 
                (R)
     </a>
     - Ex-Morgan County Commissioner &amp; State Correctional Officer
     <br/>
     Bob Starkey (R) - Retired Businessman, '10 State Rep. Candidate &amp; '12 Scottsboro Mayor Candidate
     <br/>
     <a href="http://www.bassforbama.com/">
      Kevin Bass (D)
     </a>
     - Businessman &amp; Ex-Pro Baseball Player
     <br/>
     <a href="http://www.parkergriffithforcongress.com/">
      Parker Griffith 
                (D)
     </a>
     - Ex-Congressman, Ex-State Sen., Physician &amp; Ex-Republican
    </strong>
   </font>
  </p>
 </body>
</html>

这是我用beauthulsoup实现的

上面的代码打印出如下内容：

> Robert 
                Bentley (R)*
      http://governor.alabama.gov/ 

>      Stacy George 
                (R)
      http://www.facebook.com/stacy.george.3139 
     - Ex-Morgan County Commissioner & State Correctional Officer

>      Kevin Bass (D)
      http://www.bassforbama.com/ 
     - Businessman & Ex-Pro Baseball Player


>      Parker Griffith 
                (D)
      http://www.parkergriffithforcongress.com/ 
     - Ex-Congressman, Ex-State Sen., Physician & Ex-Republican

遗漏了第三项

Bob Starkey (R) - Retired Businessman, '10 State Rep. Candidate &amp; '12 Scottsboro Mayor Candidate

请问我怎么用BeautifulSoup解决这个问题？ 我试过用find_all("br")来做，但是它不能作为br标记返回NoneType。在

抓取每个链接之外的所有文本节点：

from itertools import takewhile
from bs4 import NavigableString

not_link = lambda t: getattr(t, 'name') not in ('a', 'strong')

for link in soup.find_all("a"):
    print 'Link contents:'
    text = link.text.strip()
    for sibling in takewhile(not_link, link.next_siblings):
        if isinstance(sibling, NavigableString):
            text += unicode(sibling).strip()
        else:
            text += sibling.text.strip()
    print text

打印：
