BeautifulSoup 善于网页数据分析 ,但是 python for android : BeautifulSoup 有 bug ,
text = h4.a.text 只能取得 None,所以我写了function: getText()
来fix this bug.
例如: 抓取CSDN极客头条内容 soup.py
import urllib2, re
from BeautifulSoup import BeautifulSoup
import sys
reload(sys)
sys.setdefaultencoding(‘utf-8‘)
def getText(text):
begin = text.find(‘>‘,0)
if begin > -1:
begin += 1
end = text.find(‘</a>‘,begin)
if begin < end:
return text[begin:end].strip()
else:
return None
else:
return None
page = urllib2.urlopen("http://geek.csdn.net/new")
soup = BeautifulSoup(page)
for h4 in soup.findAll(‘h4‘):
if h4.a is not None:
href = h4.a.get(‘href‘)
text = getText(str(h4.a))
print text
print href
page.close()
