필터링 XMLListCollection 문제가

Question

나는 일종의 rangking을 만들려고합니다. 이를 위해, PHP 파일로 생성 한 다중 레벨 XML을 사용하고 있습니다.

<klassement>  
     <reeks> 
     <reeksId>1</reeksId> 
     <reeksNaam>3de klasse</reeksNaam> 
     <ploeg> 
      <ploegNaam>Foo</ploegNaam> 
      <goalsMade>60</goalsMade> 
      <points>12</points> 
     </ploeg> 
     <ploeg> 
      <ploegNaam>bar</ploegNaam> 
      <goalsMade>10</goalsMade> 
      <points>2</points> 
     </ploeg>  
     </reeks>  
     <reeks> 
     <reeksId>2</reeksId> 
     <reeksNaam>3de klasse res</reeksNaam> 
     <ploeg> 
      <ploegNaam>Foo res</ploegNaam> 
      <goalsMade>50</goalsMade> 
      <points>12</points> 
     </ploeg> 
     <ploeg> 
      <ploegNaam>bar</ploegNaam> 
      <goalsMade>40</goalsMade> 
      <points>8</points> 
     </ploeg>  
     </reeks> 
</klassement> 

등등, 등등 난 내 응용 프로그램에서 HTTPService를 가진 정보를 얻을 수 (당신은 요점을 파악). 이후에 나는 그 정보를 XMLListCollection에 넣을 것이다. 이제 레벨을 분리하려고합니다 (아마도 올바른 방법은 아니지만 작동합니다). 내가 디버깅 할 때 그 2 개의 새로운 vars에 올바른 정보가 있다는 것을 알 수 있지만 DataGrid의 dataProvider가 klassementKern이어야한다고 말하면서 "유형 XML 값의 암시 적 강제 변환이 발생했습니다. 관련이없는 형식 mx.collections : IList "

왜이 문제가 있으며 어떻게 해결할 수 있는지 알고 있습니까? harcoded XML 상수와 나를 위해
