python for android : BeautifulSoup 有 bug

Posted 2020-09-15

BeautifulSoup 善于网页数据分析 。可是 python for android : BeautifulSoup 有 bug ，

text = h4.a.text 仅仅能取得 None，因此我写了function: getText() 来fix this bug.

比如: 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()
