Override style on a balise

Hello,
Sorry but I have a question.
I using CkEditor 3.
I have defined 4 styles on the main page

<script type="text/javascript">      
CKEDITOR.replace( 'editeur',
    {
   contentsCss : 'styles_ecriture.css',
        uiColor : '#B0CC99',
   stylesSet :
   [
   { name : 'Rubrique',element : 'span' , attributes : {'class': 'rubrique'} ,overrides : { element: '*'} },
   { name : 'Sous Rubrique', element : 'span' , attributes : {'class': 'ssrubrique'}  ,overrides : { element: '*'}},
   { name : 'Important', element : 'span' , attributes : {'class': 'important'}  ,overrides : { element: '*'}},
   { name : 'Citation', element : 'span' , attributes : {'class': 'citation'}  ,overrides : { element: '*'} },
   ]
    });
</script>

I using a php script for parsing the text and in the result i have :

Tentative de reception :
<p>
   <span class="ssrubrique">[u]<span class="rubrique">[/u]The Early English Text Society, present, past and future[url]</span>[/url]</span></p>
<p>
   Anyone who reads Old and Middle English literary texts will be familiar with the mid-brown volumes of the EETS, with the symbol of Alfred&#39;s jewel embossed on the front cover. Most of the works attributed to King Alfred or to Aelfric, along with some of those by bishop Wulfstan and much anonymous prose and verse from the pre-Conquest period, are to be found within the Society&#39;s three series; all of the surviving medieval drama, most of the Middle English romances, much religious and secular prose and verse including the English works of John Gower, Thomas Hoccleve and most of Caxton&#39;s prints all find their place in the publications. Without EETS editions, study of medieval English texts would hardly be possible.</p>

But it is possible to have just
The Early English Text Society, present, past and future
For delete inner tags I look "overrides styles", but i not found the instruction for realized this action.

Thanks for your help
