Python解析：从非标准布局的html测试文件中提取数据

我需要帮助解析一个html文本文件，该文件的布局我不知道如何解析，并且可以真正使用帮助

迄今为止的代码：

import urllib,os, urllib2, webbrowser, StringIO, re
from BeautifulSoup import BeautifulSoup
from urllib import urlopen

urlfile = open('output.txt','r')

html = urlfile

soup = BeautifulSoup(''.join(html))

print soup.prettify()
table = soup.find('table', id="dgProducts__ctl2_lblCountry")
rows = table.findAll('<span id="dgProducts__ctl2_lblCountry">')

for tr in rows:
  cols = tr.findAll('td')
for td in cols:
   text = ''.join(td.find(text=True))
   print text+"|",
print

缩写的.html文件数据结构：

  <td><font color="#330099" size="1">
         <span><font size="2">
           <input id="dgProducts__ctl12_ckCompare" type="checkbox" name="dgProducts:_ctl12:ckCompare" onclick="checkSelected(this.form, this);" />

我建议您使用名为MiniDom或xml.dom.MiniDom的模块。它使解析XML和HTML文件变得容易。

只是偶然发现了

''.join（HTML）

而不是

HTML.read（）

。嗯，每个人都有自己的：）“迄今为止的代码”。。。“我想做的事”。。。和什么不起作用？你有什么问题？你需要什么帮助？
