How to get elements which have no children, but may have text?

the empty selector says that: Matches all elements that have no children (including text nodes).
Finds all elements that are empty - they don't have child elements or text.

What i want is to get elements which has no children but may have text inside., how?

UPDATE:
Example:
I want select these elements which has no children but may have text, with syntax like this:

$('div:empty, a:empty, span, p:empty, td:empty, img, input').mousemove(myMouseOverHandler);
