</div>

我有上面的结构。从那我试图只刮掉members_box1和members_box2div内的文本。class

我有以下脚本，它只从 members_box1 获取数据

from bs4 import BeautifulSoup
import urllib2
import csv
import re
page = urllib2.urlopen("http://www.codissia.com/member/members-directory/?mode=paging&Keyword=&Type=&pg=1")
soup = BeautifulSoup(page.read())
for eachuniversity in soup.findAll('div',{'class':'members_box1'}):
    data =  [re.sub('\s+', ' ', text).strip().encode('utf8') for text in eachuniversity.find_all(text=True) if text.strip()]
    print '\n'

这就是我尝试从两个盒子中获取数据的方式

from bs4 import BeautifulSoup
import urllib2
import csv
import re
page = urllib2.urlopen("http://www.codissia.com/member/members-directory/?mode=paging&Keyword=&Type=&pg=1")
soup = BeautifulSoup(page.read())
eachbox2 = soup.findAll('div ', {'class':'members_box2'})
for eachuniversity in soup.findAll('div',{'class':'members_box1'}):
    data =  eachbox2 + [re.sub('\s+', ' ', text).strip().encode('utf8') for text in eachuniversity.find_all(text=True) if text.strip()]
    print data

但我得到的结果与我只为members_box1得到的结果相同

更新

我希望输出像这样（单行）进行迭代

Name:,Mr.Srinivasan.N,Designation:,Proprietor,CODISSIA - Designation:,(Past President, CODISSIA),Name of the Industry:,Arian Soap Manufacturing Co,Specification:,LIFE,Date of Admission:,19.12.1969, "Parijaat" 26/1Shanker Mutt Road, Basavana Gudi,Phone:,2313861

但我得到如下

Name:,Mr.Srinivasan.N,Designation:,Proprietor,CODISSIA - Designation:,(Past President, CODISSIA),Name of the Industry:,Arian Soap Manufacturing Co,Specification:,LIFE,Date of Admission:,19.12.1969
"Parijaat" 26/1Shanker Mutt Road, Basavana Gudi,Phone:,2313861

问题是您要添加eachbox2到 eachdata中，而不是添加到要循环的事物列表中。

最重要的是，您有一个杂散空间，'div '而不是'div'，这会导致eachbox2成为一个空列表。

尝试这个：

eachbox1 = soup.findAll('div', {'class':'members_box1'})
eachbox2 = soup.findAll('div', {'class':'members_box2'})
for eachuniversity in eachbox1 + eachbox2:
    data =  [re.sub('\s+', ' ', text).strip().encode('utf8') for text in eachuniversity.find_all(text=True) if text.strip()]

这实际上并不是最好的做事方式，它只是对您现有的做事方式的最简单修复。BeautifulSoup 提供了多种不同的方法来在一个查询中搜索多个事物——例如，您可以基于值元组、正则('members_box1', 'members_box2')表达式 ( re.compile(r'members_box[12]')) 或过滤函数 ( lambda c: c in 'members_box1', 'members_box2') 进行搜索……</p>

您可以使用regex匹配members_box1或匹配members_box2：

import re
eachbox = soup.findAll('div', {'class':re.compile(r'members_box[12]')})
for eachuniversity in eachbox:

例如，

import bs4 as bs
import urllib2
import re
import csv

page = urllib2.urlopen("http://www.codissia.com/member/members-directory/?mode=paging&Keyword=&Type=&pg=1")
content = page.read()
soup = bs.BeautifulSoup(content)

with open('/tmp/ccc.csv', 'wb') as f:
    writer = csv.writer(f, delimiter=',', lineterminator='\n', )
    eachbox = soup.find_all('div', {'class':re.compile(r'members_box[12]')})
    for pair in zip(*[iter(eachbox)]*2):
        writer.writerow([text.strip() for item in pair for text in item.stripped_strings])

请注意，您必须在divin之后删除杂散空间

soup.findAll('div ')

为了找到任何<div>标签。

上面的代码使用了非常方便的grouper 习惯用法：

zip(*[iter(iterable)]*n)

此表达式从元组中收集n项目iterable并将它们分组。所以这个表达式允许你迭代n项目块。我试图解释石斑鱼成语在这里的工作原理很糟糕。
