網絡抓取：我只獲得我想要的文本的1/10（使用BeautifulSoup）

Question

我試圖從網頁抓取數據，並且我想要的所有文本位於<p class="heading2">和More...之間。

它適用於第一批文本，但僅適用於該文本。

E.g.我得到：

Info about grant 1 

，但該網站上有：

Info about grant 1 
Info about grant 2 
Info about grant 3 
etc. 

下面是我使用的代碼。我是BeautifulSoup的新手，所以我希望有人能幫助！

from bs4 import BeautifulSoup 
import sheetsync 
import urllib2, csv 
url = urllib2.urlopen('http://www.asanet.org/funding/funding_and_grants.cfm').read() 
def processData(): 
    url = urllib2.urlopen('http://www.asanet.org/funding/funding_and_grants.cfm').read() 
    soup = BeautifulSoup(url) 
    metaData = soup.find_all("div", {"id":"memberscontent"}) 
    authors = [] 
    for html in metaData: 
      text = BeautifulSoup(str(html).strip()).encode("utf-8").replace("Deadline", "DEADLINE").replace('\s+',' ').replace('\n+',' ').replace('\s+',' ') 
      authors.append(text.split('<p class="heading2">')[1].split('More...')[0].strip()) # get Pos 
      txt = 'grants.txt' 
    with open(txt, 'ab') as out: 
     out.writelines(authors) 
processData() 

Answer 1

我靠heading2並獲得未來兩個p標籤siblings：首先是最後期限，二是格蘭特的文字：

import urllib2 
from bs4 import BeautifulSoup 

soup = BeautifulSoup(urllib2.urlopen('http://www.asanet.org/funding/funding_and_grants.cfm')) 

for heading in soup.select('div#memberscontent p.heading2'): 
    deadline = heading.find_next_sibling('p') 
    article = deadline.find_next_sibling('p') 

    print heading.get_text(strip=True) 
    print deadline.get_text(strip=True) 
    print article.get_text(strip=True) 
    print "----"
