回答1:

As described in this post, you should not be using regex to parse HTML.

Use an XML/HTML parser instead.

回答2:

Assuming the html is well formed, you can parse the html using HtmlUnit.

You could also write you own regular expression to process the page if there is just a single table but I would highly recommend against this as regular expressions might give strange results if the page added additional tables whereas with HtmlUnit you could validate that the page has only a single table before you start to parse or just target the table you wish.

http://htmlcleaner.sourceforge.net/

http://jsoup.org/

http://jericho.htmlparser.net/docs/index.html

are the well-known html parser for java. You can use any of them.
