XML問題 - 加載空白頁面

我是XML編碼新手，現在我正在網站上工作，以幫助我提高技能。我認爲我爲頁面提供了所有的語法，但它似乎沒有工作。以下是索引頁面的代碼以及我正在嘗試使用的xml文件。XML問題 - 加載空白頁面

你將不得不把該數據在onreadystatechange事件xmlhttp對象的裝載後執行代碼：http://www.w3schools.com/ajax/ajax_xmlhttprequest_onreadystatechange.asp

xmlhttp.onreadystatechange = function() { 
    if (httprequest.readyState == 4) { 
     // Response finished 
     if (httprequest.status = 200) { 
      // everything OK 
      // Parse the data 
     } else { 
      // Something gone wrong with the request 
     } 
    } 
}

編輯：
羅在你的代碼現在，我意識到你正在使用var x = xmlDoc.getElementsByTagName("name");。這將選擇每個標籤name，包括內部。嘗試使用store獲取每個名稱而不是名稱，然後查找product。

另外，您在for循環中使用硬編碼限制。使用x.length代替：for (var i=0; i<x.length;i++)

這是我收到的時候，當我通過鍍鉻調試錯誤「遺漏的類型錯誤：無法調用空的‘的getElementsByTagName’」 –

是否已進行了更改，我說的嗎？ – rcdmk

我試圖但不確定我是否做正確的事情。我將其餘的代碼置於狀態200狀態？如果您可以請您發佈編輯的代碼，它會有所幫助。 –
