Python解析：從非標準佈局的HTML測試文件中提取數據

Question

我需要幫助解析具有我不確定如何解析的佈局的HTML文本文件，並且可以真正使用幫助。

代碼迄今：

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 

我正在嘗試做的： 我期待從html的文本文件中提取數據，並將其按以下格式提交：

Header Row: Country Company Name Company Product Name  Status 
Data Row(s): 1  Ace   Desktop  Ace Vision Gold 

簡稱.html文件數據結構：

</tr><tr bgcolor="White"> 
    <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);" /> 
      </font></span> 
     </font></td><td><font color="#330099" size="1">

我建議您使用稱爲MiniDom或xml.dom.minidom的模塊。它可以很容易地解析XML和HTML文件。
