How to read and write an xml file in Extjs 2.3?

[vibhakhushi]

Hello Everyone,
Now i am venturing the XmlReader option in Extjs. But I am unable to read an xml file. Please help me by showing the demo.
Here is my code:

var store = new Ext.data.Store({
        url:'login.xml',        
        autoLoad:true,
        reader: new Ext.data.XmlReader({
               // record will have an "loginInformation" tag
               record:'loginInformation',
               id:'ID'
               //totalRecords: '@total'
           }, [
               'USERNAME','PASSWORD'
           ])
    });
    
	store.load();
	
	alert(store.getTotalCount());

My XML File is:

<?xml version="1.0" encoding="UTF-8"?>
<loginInformation>
	<ID>1</ID>
	<USERNAME>vibha</USERNAME>
	<PASSWORD>vibha</PASSWORD>
</loginInformation>

did you have a look in Firefox's error console or the Firebug-console? do any errors occur? do you try it from a local machine or via a webserver?

I try from a local machine. I get load exception, as undefined.

as far as i know the underlying extjs ajax-request (implicitly used with specifying the url-property of the store) will only work for real http-requests and not with the file-protocol ... so you should try it with a webserver ...
