Drag and Drop Test

Question

Hi ,
I am building a Quiz where we have a Drag and Drop Question ,with Option from 1 - 5 Randomly displayed , User have to put them in a right order for the answer to be correct..When the Answer is correct , a Movie Clip Pops up showing its the Correct Answer
I am taking questions out of an XML File , but don't know how I would define a SET of option to be a correct answer in this ,
Anyone with a Code would be a great help , here is what I have in my AS3 Code
  private function fn_showQuestionDragAndDrop():void
   mc_questionDragAndDrop.visible     = true;
   mc_questionDragAndDrop.y        = (277 - ((6 -( txt_question.numLines))*21.6));
   arr_objects = new Array();
   while(mc_questionDragAndDrop.numChildren > 0)
    mc_questionDragAndDrop.removeChildAt(0);
   var arr_dragOptions:Array =  new Array();
   for(var i:uint = 0;i< xml_questions.problem[int_currentQuestion].answers.answer.length() ;i++)
    arr_dragOptions.push(xml_questions.problem[int_currentQuestion].answers.answer[i]);
   arr_dragOptions.sort(randomSort);  
   for( i = 0;i< xml_questions.problem[int_currentQuestion].answers.answer.length() ;i++)
    var mc_counter:mc_questionDragAndDropCounter       = new mc_questionDragAndDropCounter();
    mc_counter.txt_caption.text     = String(i+1)+":"
    mc_questionDragAndDrop.addChild(mc_counter);
    mc_counter.y          = 32*i;
    mc_counter.x          = 27.9;
    var mc_option:mc_questionDragAndDropOption = new mc_questionDragAndDropOption();
    mc_option.txt_caption.text     =  arr_dragOptions[i];
    mc_questionDragAndDrop.addChild(mc_option);
    mc_option.y          = 32*i;
    mc_option.x          = 48.05;
    mc_option.buttonMode       = true;
    mc_option.mouseChildren      = false;
    mc_option.id = i;
    mc_option.addEventListener(MouseEvent.MOUSE_DOWN,fn_mouseDown);
    mc_option.addEventListener(MouseEvent.MOUSE_UP,fn_mouseDown);
    arr_objects.push(mc_option);
    mc_option.X = mc_option.x;
    mc_option.Y = mc_option.y;
Here is the XML Code
<problem id = "4">
  <question type = "DragAndDrop" >At uncontrolled intersections or situations, the hierarchy rule applies. Drag and drop the below into the correct hierarchical order.</question>
  <answers correct = "1">
   <answer>Emergency vehicles driving under priority flashing lights &amp; siren</answer>
   <answer>Explosive trucks, working graders and dozers</answer>
   <answer>Haul trucks</answer>
   <answer>Other heavy equipment</answer>
   <answer>Light vehicles</answer>
  </answers>
</problem>
How can I define a Pattern to be Correct Answer in this case?

Answer 1

Thanks a lot for the help ,
I tried the Code with addition of adding a Movie Clip (correct) or (wrong) based on answer  to it which I am doing with the rest of the questions , but its not doing anything
Here is my Code , Part of the Problem can be that there is NO one Correct Answer here , actually , user have to set the Lines of Text in the right order and that would be considered a correct answer
Here is my Code in AS3
if(Boolean( xml_questions.problem[int_currentQuestion].answers.answer.@correct)){
    correct.visible        = true;
    correct.correct_txt.text      = String("Correct Answer");
    Root.arr_score[int_currentQuestion]   = 1;
   }else{
    attempt--;
    wrong.visible = true;
    wrong.wrong_txt.text = String("Wrong Answer - " + attempt + " /3 Attempts");
    Root.arr_score[int_currentQuestion]   = -1;   
and in the XML I did what you asked , but I don't know how to set it up that Flash would understand that the Selection is in the Right Order now
