Creating empty movie clips in a class

I have a project in which I am using classes…

I want to use a class in where from a xml object I create an array of movie clips using createEmptyMovieClip …but I can’t figure out how…

here is a my code

class classes.Patratel extends MovieClip
{

var mcPatratel:MovieClip;


function Patratel(_parinte:MovieClip)
 {
     this.mcPatratel =_parinte;
       
     createMc();
     
 }
 
 function creazaMc()
 {
   
     var mcTemp:MovieClip=new MovieClip();
     this.mcPatratel.createEmptyMovieClip("mcTemp",this.mcPatratel.getNextHighestDepth());
     mcTemp.beginFill(0x009000,100);
     mcTemp.lineTo(100,0);
     mcTemp.lineTo(100,100);
     mcTemp.lineTo(0,100);
     mcTemp.lineTo(0,0);
     mcTemp.endFill();
     
  
   

     
     
 }

}
