問題過濾XMLListCollection

我正在嘗試創建某種類型的rangking。爲此，我使用一個多層次的XML，我用一個PHP文件創建。問題過濾XMLListCollection

<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>

依此類推，等等（你明白了）我在我的應用程序中使用httpService獲取信息。之後，我將這些信息放入XMLListCollection中。現在我試圖分開水平（可能不是正確的方式，但它的工作原理）。當我調試我可以看到，這2個新的變種都有正確的東西在裏面，但是當我說當datagrid的dataProvider必須是klassementKern時，我得到錯誤「將一個XML類型的值隱式強制轉換爲無關類型mx.collections：IList「

有人知道這是爲什麼，我該如何解決這個問題？

試圖通過創建XML文件data.xml中已提供。它的工作，沒有錯誤。請確認klassement.php提供了正確的xml，您可以在螢火蟲中檢查服務器響應。 – Diode 2011-12-24 19:00:58

當我在chrome中打開php腳本時，它給了我正確的xml結構，當我在flash builder klassement中進行調試時，klassementKern和klassementReserve中充滿了正確的信息，但我沒有獲取datagrid中的信息。我今天下午把它放在網上。到php文件的鏈接是http://www.dehertoghnathalie2011.dreamhosters.com/flexScripts/klassement.php（域名是爲了別的，但我們必須將php文件放入同一個帳戶，新文件夾中）。現在我通過對數據網格和標題進行硬編碼來解決這個問題，但是httpsService – 2011-12-24 23:40:46

我找到了解決辦法。我會在下面發佈我的新代碼，以防別人遇到同樣的問題。

對我的作品與harcoded XML恆定的，所以你可能會從服務器獲取別的東西：

會更好，但是您只能獲取一個數據網格嗎？我需要2個，一個是'克恩'，一個是'儲備'。爲什麼它會顯示數據，如果你硬編碼，而不是當我使用httpService？我發現奇怪的:)（或者是因爲我在這= D新） – 2011-12-24 23:45:01

也許是因爲HTTP服務提供了其他東西，如錯誤文本？ – 2011-12-25 17:54:41

沒有httpService給我正確的信息。鏈接到php文件（創建xml寫在上面的註釋中）。當我調試它時，我可以在所有變量中看到正確的信息 – 2011-12-25 20:17:13
