Hello Friends,

I have an xml file Users.xml

<?xml version .....?>
<users>
<user>
<cid>101</cid>
<name>poonam</name>
</user>
</users>

I've written the following code to add a user node , but it's not working.
What is wrong with the code?

<html>
<head>
<script type="text/javascript">
var name,cid;
var xmlDoc;
function add(form1)
{
name=form1.name.value;
cid=form1.cid.value;
loadXML();
}

function loadXML()
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("Users.xml");
parseXML();
}

function parseXML()
{
var x=xmlDoc.documentElement;
alert(x.nodeName+"nodename");
var newNode=xmlDoc.createElement("user");
var newCid=xmlDoc.createElement("cid");
var newName=xmlDoc.createElement("name");
var newcidText=xmlDoc.createTextNode(cid);
var newnameText=xmlDoc.createTextNode(name);

newCid.appendChild(newcidText);

newName.appendChild(newnameText);

newNode.appendChild(newCid);
newNode.appendChild(newName);
x.appendChild(newNode);
//xmlDoc.appendChild(x);

}

</script>
</head>
<body>
<form onsubmit="add(this)">
<center>Name : <input type="text" name="name" size="50"></center>
<center>CID : <input type="text" name="cid" size="50"></center>
<center><input type="submit" value ="go"></center>
</form>
</body>
</html>

but it's not working.

At what point do you determine that it is "not working"? Does the host computer explode, freeze up, turn to dust

In other words, what happens when you try it?

I've written the code to add a user node in Users.xml
The code is supposed to take the values of "cid" and "name" from the html
page and add those to the Users.xml
But after execution no node is added to the Users.xml

Thats probably because you have only modified the DOM in memory. The Users.xml remains unchanged because you have not written the modified DOM over it. This section of Sun's tutorial should get you started.
