Python 解析HTML表的内容-但iframe是问题的根源

今天的最后一个问题。我试图找到一种方法来解析这个页面的表的内容：在一个var中，把它放在一个Excel文件中

使用BeautifulSoup解析数据后，将数据放入excel没有问题

但是（总是有一个“但是”）源代码非常奇怪，里面有一个iframe

#!/usr/bin/python
# -- coding: utf-8 --

import xlwt
import urllib2
import sys
import re
from bs4 import BeautifulSoup as soup
import urllib

print("TEST FOR PTE TESTS CENTERS")

url = 'http://www6.pearsonvue.com/Dispatcher?application=VTCLocator&action=actStartApp&v=W2L&cid=445'
values = {
        'sortColumn' : 2,
        'sortDirection' : 1,
        'distanceUnits' : 0,
        'proximitySearchLimit'  : 20,
        'countryCode'  : 'GBR', # WE TRY FOR NOW WITH A SPECIFIC COUNTRY

            }

user_agent = 'Mozilla/5 (Solaris 10) Gecko'
headers = { 'User-Agent' : user_agent }

data = urllib.urlencode(values)
req = urllib2.Request(url, data, headers)
response = urllib2.urlopen(req)
thePage = response.read()
the_page = soup(thePage)


result = the_page.find('frame', attrs={'name' : 'VTCLocatorPageFrame'})
print result # We have now the FRAME link in the result var

因此，请在上面找到我正在努力工作的脚本的源代码

运行脚本后，我们在结果变量中有以下内容：

如果您有任何想法，它可能会非常有用：）

提前感谢并通过python

对不起，这个问题不太清楚。我试图找到解决方案，以下是我使用的脚本：

我认为问题来自我使用的URL。我猜id正在从请求更改为另一个。。。 http://www6.pearsonvue.com/Dispatcher?v=W2L&application=VTCLocator&HasXSes=Y&layerPath=ROOT.VTCLocator.SelTestCenterPage&wscid=199372577&layer=SelTestCenterPage&action=actDisplay&bfp=top.VTCLocatorPageFrame&bfpapp=top&wsid=1334887910891

它已经正常工作了一个小时，现在不再是了！：-）

如果您必须过滤/解析iframe，代码就在这里

from bs4 import BeautifulSoup
import urllib2

page = urllib2.urlopen("put_ur_url")
soup = BeautifulSoup(page)
    for link in soup.findAll('iframe'):
        if link['src'].startswith('start_of_path'):
            print(link)

根本不清楚你在问什么…很抱歉。如果您进入该页面，您将看到通过在列表中进行选择，您将访问一个包含测试中心名称、国家和地区的表。我想找到一种解析此数据的方法：-）
