Remove text lines that are empty?

In our workflow for pre-press, we get a lot of documents that we need to optimize, and very often something that gets in the way are lines with empty text. Usually it's just a space or a hard return, no other characters are in the text field. It tends to throw off the whole page when we try to automatically scale it because the page is using that empty text box when it scales and the text is in a weird spot. If we could remove these sorts of text boxes, that would be amazing.

Seems like a simple script should do the trick. Any help appreciated.
