screen-scraping

Hey guys, i'm really trying to understand regular expressions while scraping a site, i've been using it in my code enough to pull the following, but am stuck here. I need to quickly grab this:

http://www.example.com/online/store/TitleDetail?detail&sku=123456789

from this:

('<a href="javascript:if(handleDoubleClick(this.id)){window.location=\'http://www.example.com/online/store/TitleDetail?detail&sku=123456789\';}" id="getTitleDetails_123456789">\r\n\t\t\t            \tcheck store inventory\r\n\t\t\t            </a>', 1)

This is where I got confused. any ideas?
