How to get stuff from <script> tag?

[Romamok]

I have:

<aside id="box-sounds" class="clearfix list-files">                       
   <script>
        jQuery(function ($) {
    //some javascript bloat                                          
        });
    </script>
    <div id='player-main-audycja_2422547' class="player-main-audycja"></div>
</aside>

I'm trying to get it out with:

@Selector(".list-files > script")
var l3: String? = null

but I'm getting empty String.
