Getting rid of white space in an array

Hi,

I'm doing some web scraping and at the end I end up with an array.

$list[] = array('link' => $link, 'types' => $types);

Sometimes name is empty so I end up with an array like this:

Array
(
    [0] => Array
        (
            [link] => 
            [types] => Array
                (
                )

        )

    [1] => Array
        (
            [link] => 
            [types] => Array
                (
                )

       )
    [2] => Array
        (
            [link] => http://example.com
            [types] => Array
                (
                )

        )
)

Is there any way I'd be able to get rid of all the  values that are empty and so each new link starts at key 0?

Thanks
