後でデータを使用するためにハンドル項目を取得しようとしています。ただし、5番目の項目で失敗しているようです。私がこれを行うとき：

var xml = new XMLHttpRequest();

xml.onreadystatechange = function ()
{
   if(xml.readyState == 4)
   {
      var xmlDoc = xml.responseXML;
      if(!xmlDoc)
      xmlDoc = (new DOMParser()).parseFromString(xml.responseText, 'text/xml');

      var handle_list = xmlDoc.getElementsByTagName("handle");

      console.log(handle_list);
   }
}

コンソールでこれを受け取ります：

[handle, handle, handle, handle, handle, item: function]
0: handle
1: handle
2: handle
3: handle
4: handle
length: 5
__proto__: NodeList

また、ログのインデックス 4 の項目は不完全です。ここで何が間違っていますか？

この質問を回答済みとしてマークできる回答のように思われるので、コメントを回答として追加します。

パーサーが停止するタグの周囲のxmlファイルにエスケープされていないアンパサンドがあります。おそらくそれがあなたの問題の原因ですか？
