Ext XmlReader 得不到数据

[mominghuan]

我是用google app engine 来测试的。

可是怎么也载入不到xml的数据。 请各位帮忙看看~~~！

test.js

systemformPanel = Ext.extend(Ext.form.FormPanel,{
	
	_record : new Ext.data.Record.create(["name" , "address" ,"email","phone"]),
	
	_store : new Ext.data.Store({
		autoLoad:true,
		url:"http://localhost:8080/xml",
		reader:new Ext.data.XmlReader({record:"person"} ,this._record)
	}),
	
	constructor:function(){
	
		systemformPanel.superclass.constructor.call(this, {
		
			renderTo:Ext.getBody(),
			frame:true,
			width:692,
			height:165,
			bodyStyle:'padding:5px',
			monitorValid:true,
			layout:'form',
			labelWidth:60,
			title:'XmlReader Test',
			labelAlign:'right',
			store:this._store,
			items:[{
				xtype:'panel',
				layout:'column',
				fieldLabel:'Name',
				isFormField:true,
				items:[{//第一行
				
					columsWidth:.5,
					xtype:'textfield',
					dataIndex:"name",
					allowBlank:false,
					blankText:'pls input',
					width:230,
					name:'name',
					anchor:'90%',
				},{
				
					columnWidth:.999,
					layout:'form',
					labelWidth:78,
					labelAlign:'right',
					items:[{
					
						xtype:'textfield',
						fieldLabel:'Address',
						dataIndex:"address",
						allowBlank:false,
						name:'address',
						anchor:'95%'
					}]
				}]
			},{//第二行
				xtype:'panel',
				layout:'column',
				fieldLabel:'Email',
				isFormField:true,
				items:[{
					
					columnWidth:.370,
					xtype:'textfield',
					dataIndex:"email",
					allowBlank:false,
					vtype:'email',
					vtypeText:'格式错误~！',
					name:'email',
					anchor:'90%'
				},{
				
					columnWidth:.633,
					layout:'form',
					labelWidth:78,
					items:[{
					
						xtype:'textfield',
						dataIndex:"phone",
						name:'phone',
						allowBlank:false,
						fieldLabel:'Phone',
						anchor:'95%'
					}]
				}]
			
			},{//第三行
			
				
			}],
			buttons:[{
			
				text:'OK',
				handler:this.onSubmitClick,
				scope:this,
			}]

		});
		//this._store.load();
	},
	onSubmitClick:function(){
		alert(this._store.getCount());
	},
	setValues:function(){
		
	},
});

http://localhost:8080/xml 请求的xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<dataset>
    <person>
        <name>abcd</name>
        <address>abcd</address>
        <email>[e-mail]</email>
        <phone>1234567</phone>
    </person>
</dataset>

html文件如下：

<link rel="stylesheet" type="text/css" href="/js/ext/resources/css/ext-all.css" />
<script type="text/javascript" src="/js/ext/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="/js/ext/ext-all.js"></script>
<script type="text/javascript"  src="/js/test.js" ></script>

<script type="text/javascript">
Ext.onReady(function(){
	var _formPanel = new systemformPanel();
});

</script>
