XML Search

I’ve got this code to save my feed as a useable list but I want to search the feed and only display those with a certain tag in <media:category>

        private function onResult( event : ResultEvent ) : void 
        {
            var pattern : RegExp = /media:/;
            var string : String = event.result as String;
            
            while( string.search( pattern ) >= 0 )
            {
              string = string.replace( pattern, "_" );
            }
            
            var data : XMLList = (new XML( string )).channel.item;
            list.dataProvider = data;
            loadingData = false;
            
             
        }

The feed:

</media:category>

</rss>

So in pseudo SQL code I want to:
SELECT * FROM feed WHERE media:category=mySearchVariable

So how would I do this to my XMLList?

something like:

for each XMLList item
{
if data._category = mySearchVariable
{
add item to new XMLList
}
}
