使用BeautifulSoup只考慮網頁內容的某個部分

Question

我怎樣才能讓BeautifulSoup只考慮網頁內容的某個部分？

例如，我要拿起所有div標籤後僅「最看現在」 http://www.dailypress.com/在頁面上。

有云：

from bs4 import BeautifulSoup 
import urllib2 

url = ' http://www.dailypress.com/ ' 
page = urllib2.urlopen(url) 
soup = BeautifulSoup(page.read()) 

，我可以使用：

str(soup).find(' Most viewed right now') 

找到這句話，但它不是在確定我想要的部分內容很有幫助。

查找出包含最多人看的文章的div，發現各個環節裏面：

>>> from bs4 import BeautifulSoup 
>>> import urllib2 
>>> import re 
>>> url = "http://www.dailypress.com" 
>>> soup = BeautifulSoup(urllib2.urlopen(url)) 
>>> most_viewed = soup.find('div', class_=re.compile('mostViewed')) 
>>> for item in most_viewed.find_all('a'): 
...  print item.text.strip() 
...

這裏的竅門是，我們首先找到容器Most Viewed鏈接 - 這是一個div有mostViewed類。您可以藉助瀏覽器開發工具來檢查它。
