有没有办法擦除或分离网页抓取数据？ 在Python中

Question

Hello I'm scraping the lastest news from ABC News website, the code i'm scraping looks like this:

 <a href="/Politics/huckabee-draws-cheers-fundraiser-west-bank-settlement/story?id=35615831" name="lpos=widget[A_3_freeformlite_4380645_homepage]&amp;lid=link[Headline_2]">Huckabee Draws Cheers at Fundraiser for West Bank Settlement<span class="metaH_timeDay">41 minutes ago</span></a>

But as you notice i got one span tag inside an a tag so when i scrape this with BeautifulSoup i get the info like this:

Huckabee Draws Cheers at Fundraiser for West Bank Settlement41 minutes ago

But it gives me the time exactly next to my data and i would like to have separated 41 minutes so it could look like this:

Huckabee Draws Cheers at Fundraiser for West Bank Settlement 41 minutes ago

or at least erase it!.

my code looks like this:

import requests
from bs4 import BeautifulSoup

url = "http://abcnews.go.com/"

r = requests.get(url)

soup = BeautifulSoup(r.content, "lxml")

for x in range(1,10):
   for link in soup.find_all("a",{"name": "lpos=widget[A_3_freeformlite_4380645_homepage]&lid=link[Headline_"+str(x)+"]"}):
    print link.text
    print link.find_all("",{"class": "metaH_timeDay"})[0].text
    print ""

Can someone help me?

Answer 1

Let's extract it via extract() :

>>> link.span.extract()     # remove the first `span` tag that we don't need
>>> time = link.span.extract()
>>> time
<span class="metaH_timeDay">2 hours, 45 minutes ago</span>
>>> link.text
' Obama Seeks to Remove Fear From ISIS Fight'
>>> time.text
'2 hours, 45 minutes ago'
>>> 

Answer 2

You can use decompose() function too-run a while lop to remove all span tag from that div -

import requests
from bs4 import BeautifulSoup

url = "http://abcnews.go.com/"

r = requests.get(url)

soup = BeautifulSoup(r.content, "html.parser")

for x in range(1):
    d=soup.select("div.h a")
    for j in d:
        j = str(j)
        f = BeautifulSoup(j,'html.parser')
        while f.span:
            f.span.decompose()
        print f.text.encode('utf-8') 

Output-
