下面代碼是用來建立xml對象，並載入本地xml檔案

 

<html>
<head>
<script type="text/javascript">
function parseXML()
{
try //Internet Explorer
  {
  xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
  }
catch(e)
  {
  try //Firefox, Mozilla, Opera, etc.
    {
    xmlDoc=document.implementation.createDocument("","",null);
    }
  catch(e)
    {
    alert(e.message);
    return;
    }
  }
xmlDoc.async=false;
xmlDoc.load("/example/xmle/note.xml");
document.getElementById("to").innerHTML=xmlDoc.getElementsByTagName("to")[0].childNodes[0].nodeValue;
document.getElementById("from").innerHTML=xmlDoc.getElementsByTagName("from")[0].childNodes[0].nodeValue;
document.getElementById("message").innerHTML=xmlDoc.getElementsByTagName("body")[0].childNodes[0].nodeValue;
}
</script>
</head>

<body onload="parseXML()">
<h1>W3Schools Internal Note</h1>
<p><b>To:</b> <span id="to"></span><br />
<b>From:</b> <span id="from"></span><br />
<b>Message:</b> <span id="message"></span>
</p>
</body>
</html>

 

顯示結果如下：

W3Schools Internal Note

To: George
From: John
Message: Don't forget the meeting!

 

 

載入並解析xml 字串

 

<html>
<head>
<script type="text/javascript">
function parseXML()
{
text="<note>";
text=text+"<to>George</to>";
text=text+"<from>John</from>";
text=text+"<heading>Reminder</heading>";
text=text+"<body>Don't forget the meeting!</body>";

try //Internet Explorer
  {
  xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
  xmlDoc.async="false";
  xmlDoc.loadXML(text);
  }
catch(e)
  {
  try //Firefox, Mozilla, Opera, etc.
  {
  parser=new DOMParser();
  xmlDoc=parser.parseFromString(text,"text/xml");
  }
  catch(e)
  {
  alert(e.message);
  return;
  }
}
document.getElementById("to").innerHTML=xmlDoc.getElementsByTagName("to")[0].childNodes[0].nodeValue;
document.getElementById("from").innerHTML=xmlDoc.getElementsByTagName("from")[0].childNodes[0].nodeValue;
document.getElementById("message").innerHTML=xmlDoc.getElementsByTagName("body")[0].childNodes[0].nodeValue;
}
</script>
