这是我要处理的html文件:

Here is the html file I am going to handle:

<span class="pl">Countries:</span> USA <br/>
<span class="pl">Language:</span> English <br/>

这是我的python代码:

And here is my python code:

from bs4 import BeautifulSoup

record=[]
soup=BeautifulSoup(html)
spans=soup.find_all('span')
for span in spans:
   record.append(span.text)
