在網上找到一個通過js解析xml的例子，覺得不錯，就轉了過來可以參考看看
一個簡單的xml文件：
<?xml version="1.0" encoding="ISO-8859-1" ?> - <!-- Copyright w3school.com.cn --> - <note> <to>George</to> <from>John</from> <heading>Reminder</heading> <body>Don't forget the meeting!</body> </note>
加載並解析xml文件：
<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("heading").innerHTML=xmlDoc.getElementsByTagName("heading")[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 οnlοad="parseXML()">
<h1>javascript解析xml</h1>
<p><b>To:</b> <span id="to"></span><br />
<b>From:</b> <span id="from"></span><br />
<b>heading:</b> <span id="heading"></span><br />
<b>Message:</b> <span id="message"></span>
</p>
</body>
</html>
運行結果爲：
To: George
From: John
heading: Reminder
Message: Don't forget the meeting!
遍歷xml節點數：
<html>
<body>
<script type="text/javascript">
var xmlDoc;
// code for IE
if (window.ActiveXObject)
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
}
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation.createDocument)
{
xmlDoc=document.implementation.createDocument("","",null);
}
else
{
alert('Your browser cannot handle this script');
}
xmlDoc.async=false;
xmlDoc.load("/example/xmle/note.xml");
var x=xmlDoc.documentElement.childNodes;
for (var i=0;i<x.length;i++)
{
if (x[i].nodeType==1)
{
//Process only element (nodeType 1) nodes
document.write(x[i].nodeName + ": ");
document.write(x[i].childNodes[0].nodeValue);
document.write("<br />");
}
}
</script>
</body>
</html>
運行結果爲：
to: George
from: John
heading: Reminder
body: Don't forget the meeting!
