ext中ArrayStore,JsonStore,XmlStore的用法

1.Store的用法 

var _store = new Ext.data.Store(); 
    
    var _record = new Ext.data.Record(["name","sex"]); 
    
    var _recordClone = new Ext.data.Record(["name","sex"]); 
    
    _record.set('name','张翔'); 
    
    _record.set('sex','男'); 

  _store.add(_record); 
  
  _recordClone.set('name','李慧敏'); 
    
    _recordClone.set('sex','女'); 
    
    _store.add(_recordClone); 
    
    //alert(_store.getCount()); 
    
    //alert(_store.getAt(1).get('sex')); 

2.ArrayStore的用法 
var _store = new Ext.data.ArrayStore({ 
  
  data:[{name:'张翔',sex:'男'},{name:'李慧敏',sex:'女'}], 
  
  fields:[{name:'name',mapping:'name'},{name:'sex',mapping:'sex'}] 
  }); 
  
  alert(_store.getAt(1).get('sex')); 

3.JsonStore的用法(和ArrayStore差不多，2.0版本之前 ArrayStore是JsonStore的子类) 
var _store = new Ext.data.JsonStore({ 
  
  data:[{name:'张翔',sex:'男'},{name:'李慧敏',sex:'女'}], 
  
  fields:[{name:'name',mapping:'name'},{name:'sex',mapping:'sex'}] 
  });	
  alert(_store.getAt(1).get('sex')); 

4.XmlStore的用法 
var _emp = Ext.data.Record.create([{name:'name',mapping:'name'},{name:'sex',mapping:'sex'}]); 
  var _store = new Ext.data.XmlStore({ 
  
  url:'/store/xmlStore.xml', 
  
  reader:new Ext.data.XmlReader({ 
  totalRecords:'xml', 
  record:'emp', 
  id:'id' 
  },_emp) 
  }); 
  
  _store.load(); 
  
  alert(_store.getCount()); 
  
  alert(_store.getAt(1).get('sex'));

您好，能否请教下XmlStore的使用方法
var store3 = new Ext.data.XmlStore({
   storeId: 'myStore',
autoLoad : true,
model: 'User',
url : 'user.xml',
record : 'user'
});
我这样子的写法有什么问题么？
