i´m looking for a way to check a list for equal content and then hide this li.

f.e.:

1. 
   

<ul>

     <li class="static"><a href="#">plakat</a></li>    

<li class="static"><a href="#">plakat</a></li>

<li class="static"><a href="#">plakat</a></li>

<li class="static"><a href="#">katalog</a></li>

<li class="static"><a href="#">katalog</a></li>

</ul>

should be changed to:

1. 
   

<ul>

     <li class="static"><a href="#">plakat</a></li>    

<li class="static"><a href="#">katalog</a></li>

</ul>

i tried .unique but can´t see the way.

thanks for your help!
