[jQuery] make a div invisible when it is empty

[Discret]

Good morning,

I am Graphic designer and I use Jquery with Moss (sharepoint) CMS
Microsoft,  developers of  this gas plant have no sense of aesthetics
code and optimization.
I assumed that with a little magic wand, I was going to do div
disappear when they are empty, then yes I could have use easily use.
empty (), but generates sharepoint   and I can not delete
upstream. This small function
is not much in this case.

<script type="text/javascript">

   $(document).ready(function () {
   $("#header div empty").hide("slow");
 });

</script>


 <div id="header">
                   <div id="Auteur" style="">&nbsp;</div>
                    <div id="Date" style="">&nbsp;</div>
                    <div id="accroche-page" style=""><div dir=""></
div>&nbsp;</div>
  </div>



Can you help me please
