如数据格式如下：
<? xml version = "1.0" encoding = "UTF-8" ?>
< Bills >
??? < Bill >
?????? < Ad > SC2AAk99 </ Ad >
?????? < Count > 4 </ Count >
?????? < Money > 100.32 </ Money >
?????? < Type > 后符费 </ Type >
?????? < Orders >
?????????? < Order >

这是一个多层嵌套记录,使用XML无法解析,如下：
var store = new Ext.data.Store({
?????? proxy: new Ext.data.HttpProxy({
?????????? url : './RowExpanderGrid.xml' ,
?????????? method : "GET"
?????? }),
?????? reader: new Ext.data.XmlReader ({
?????????? totalRecords : "TotalRecord" ,
?????????? record : 'Bill'
?????? }, [ 'Ad' , 'Count' , 'Money' , 'Type' , 'Orders' ])??
});
store.on( "load" , function (t, r, o){ ?
??? alert(r.length);????
})
??? store.load();

使用JsonStore可以解析出内层来：
{
??? bills : [{
?????? ad : "SC2AAk99",
?????? count: 1,
?????? money: 123 ,
?????? type: 1,
?????? order: [
?????????? {id: 1, no: 11, name: "name11", money: '100'},
?????????? {id: 2, no: 12, name: "name12", money: '100'},
?????????? {id: 3, no: 13, name: "name13", money: '100'},
?????????? {id: 4, no: 14, name: "name14", money: '100'}
?????? ]?????
??? }, {
?????? ad : "SC2AAk98",
?????? count: 2,
?????? money: 22 ,
?????? type: 1,
?????? order: [
?????????? {id: 21, no: 211, name: "name211", money: '200'},
?????????? {id: 22, no: 212, name: "name212", money: '200'},
?????????? {id: 23, no: 213, name: "name213", money: '200'},
?????????? {id: 24, no: 214, name: "name214", money: '200'}
?????? ]?????
??? }]
}
