The best way should be to google for regexes. One example is this one:

    /^(https?):\/\/((?:[a-z0-9.\-]|%[0-9A-F]{2}){3,})(?::(\d+))?((?:\/(?:[a-z0-9\-._~!$&'()+,;=:@]|%[0-9A-F]{2})))(?:\?((?:[a-z0-9\-._~!$&'()+,;=:\/?@]|%[0-9A-F]{2})))?(?:#((?:[a-z0-9\-._~!$&'()+,;=:\/?@]|%[0-9A-F]{2})*))?$/i

found in a hacker news article. As far as I can follow it, it looks good. But there is, as far as I know, no formal regex for this problem. So the best solution is to google for some and try which one matches most of what you want.
