<a href="aaaas"><img src="saaa"/></a>
<a class="url" href="saasa">那個分享第二份職業(yè)，兩個月...</a>
<a href="aaaaa"><img src="aaaaa"></a>
<a class="url" href="aaaaa">兼職一：這是一個在手機(jī)上賺...</a>
<a href="saa">緇欐垜鍏蟲敞鐨勪漢鍐欎俊</a>
<a href="saaaat">鍘繪垜鍏蟲敞鐨勪漢鍒楄〃</a>

我想匹配出class="url"標(biāo)簽

1. from bs4 import BeautifulSoup
   
2. import string, re
   
3. 
   
4. f = open('dy.html', 'r')
   
5. html = f.readlines()
   
6. soup = BeautifulSoup(string.join(html, ''))
   
7. for link in soup.find_all('a'):
   
8.     print link.find(class_='url')
   
9.     print link.find(attrs={'class','url'})

復(fù)制代碼

都顯示None

問題解決了，得這么搞

1. 
   
2. soup = BeautifulSoup(self.response.read())
   
3. tag = soup.find_all('span', attrs={'class':'from'})
   
4. tag2 =  soup.find_all('a', attrs={'class':'url'})
