loadxml.htm

<html>
<head>
<script>
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)}
} 
try
{ 
xmlDoc.async=false;
xmlDoc.load("books.xml");
document.write(xmlDoc.getElementsByTagName("title")[0].childNodes[0].nodeValue); }
catch(e){alert(e.message);}
</script>
</head>
<body>
</body>
</html>

上述示例演示了如何加载并解析 XML 文件，而在实际开发中，XML 数据往往以自定义字符串的形式存在，这种情况通常在后台语言处理或动态生成数据时更为常见。

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