Question

我想用python捕获html中的一些文本。例如..

#!/usr/bin/python
import urllib

open = urllib.urlopen('http://localhost/main.php')
read = open.read()
print read

和目标网址的源代码

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252" />
<title>Untitled Document</title>
</head>

<body>
This is body!
</body>
</html>

如果我只想听到“这是身体！”只要！？请伙计们，帮我解决这个问题！

例如，HTML被这一个取代：

<table width=90% align=center>
  <tr>
    <td>The information available on this site freely accessible to the public</td>
  <tr>
</table>
<table class=adminlist border=0 width=90% cellpadding=3 cellspacing=0 align=center>
  <tr>
    <td rowspan=5 colspan=2><img src=images/Forum.png><br></td>
  </tr>
  <tr>
    <td><i><b>Phone</b></td><td>: +61 2 4446 5552</td>
  </tr>
  <tr>
    <td><i><b>Name</b></td><td>: Stundet</td>
  </tr>
  <tr>
    <td><i><b>Class</b></td>
    <td>: Summer</td>
  </tr>
  <tr>
    <td><i><b>Email</b></td>
    <td>: student@localhost.com</td>
  </tr>
</table>

我想做这个输出：

Phone : +61 2 4446 5552
Name  : Student
Class : Summer
Email : student@localhost.com

只抓住了html核心的话......：）
