你应该看看regular expression to extract text from HTML

从那篇文章中：

You can't really parse HTML with regular expressions. It's too complex. RE's won't handle will work in a browser as proper text, but might baffle a naive RE.

You'll be happier and more successful with a proper HTML parser. Python folks often use something Beautiful Soup to parse HTML and strip out tags and scripts.

Also, browsers, by design, tolerate malformed HTML. So you will often find yourself trying to parse HTML which is clearly improper, but happens to work okay in a browser.

You might be able to parse bad HTML with RE's. All it requires is patience and hard work. But it's often simpler to use someone else's parser.
