Hi All,

I am new to this technology and I am trying to create a tree structure from XML. I am able to create it inside the Ext.Panel. However i want to be able to create the tree inside a EditorGridPanel so that i can edit as well as I can show the tree inside a grid. I also want to show columns in the Grid. Can some one help me with this? Beow is my Code:

<script type="text/javascript" src="{!URLFOR($Resource.ExtJS3,'ext-3.3.1/adapter/ext/ext-base.js')}"/> 
	<script type="text/javascript" src="{!URLFOR($Resource.ExtJS3,'ext-3.3.1/ext-all.js')}"/>
	<script type="text/javascript" src="{!$Resource.XMLTreeLoader}"/>
		// Extend the XmlTreeLoader to set some custom TreeNode attributes specific to our application:
		Ext.app.HierarchyLoader = Ext.extend(Ext.ux.tree.XmlTreeLoader, {
		    processAttributes : function(attr)
		            // Set the node text that will show in the tree since our raw data does not include a text attribute:
		            attr.text = attr.Name ;
		            // Override these values for our folder nodes because we are loading all data at once.  If we were
		            // loading each node asynchronously (the default) we would not want to do this:
		            attr.loaded = true;
		            attr.expanded = true;
		    new Ext.Panel({
		        title: 'Account Hierarchy',
			    renderTo: 'tree',
		        layout: 'border',
			    width: 500,
		        height: 500,
		        items: [{
		            xtype: 'treepanel',
		            id: 'tree-panel',
		            region: 'center',
		            margins: '2 2 0 2',
		            autoScroll: true,
			        rootVisible: false,
			        root: new Ext.tree.AsyncTreeNode({
			        									editable: true

XML Tree Loader:

				 * [email protected]
				 * http://www.sencha.com/license
				 * @class Ext.ux.tree.XmlTreeLoader
				 * @extends Ext.tree.TreeLoader
				 * <p>A TreeLoader that can convert an XML document into a hierarchy of {@link Ext.tree.TreeNode}s.
				 * Any text value included as a text node in the XML will be added to the parent node as an attribute
				 * called <tt>innerText</tt>.  Also, the tag name of each XML node will be added to the tree node as
				 * an attribute called <tt>tagName</tt>.</p>
				 * <p>By default, this class expects that your source XML will provide the necessary attributes on each
				 * node as expected by the {@link Ext.tree.TreePanel} to display and load properly.  However, you can
				 * provide your own custom processing of node attributes by overriding the {@link #processNode} method
				 * and modifying the attributes as needed before they are used to create the associated TreeNode.</p>
