- * @class Ext.ux.tree.XmlTreeLoader
- * @extends Ext.tree.TreeLoader
- * 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 innerText. Also, the tag name of each XML node will be added to the tree node as
- * an attribute called tagName.
- * 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.
- * @constructor
- * Creates a new XmlTreeloader.
- * @param {Object} config A config object containing config properties.
