今天的最后一个问题。我正在尝试找到一种方法来解析此页面表格的内容：http ://www7.pearsonvue.com/Dispatcher?application=VTCLocator&action=actStartApp&v=W2L&cid=445 in a var，用于将其放入 Excel文件。

用 BeautifulSoup 解析后将数据放入 excel 没有问题。

但是（总是有一个“但是”）源代码很奇怪，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

所以请在上面找到我正在尝试工作的脚本的来源。

运行脚本后，我们在结果 var 中有这个：

如果您有任何想法，它可能会非常有帮助:)

在此先感谢并通过 python ！

很抱歉这个问题不是很清楚。我试图找到一个解决方案，这是我使用的脚本：

                                    pass

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 =顶部&wsid=1334887910891

它已经工作了一个小时，现在不行了！:-)

如果您必须过滤/解析 iframe，代码在这里...

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)
