xml返回的是 HddzReportDataSeries  这个是一个数组。里面又包含了一datapoints的数组，请问，extjs中 xmlreader该如何定义啊？谢谢

参考：
var Employee = Ext.data.Record.create([
   {name: 'name', mapping: 'name'},     // "mapping" property not needed if it is the same as "name"
   {name: 'occupation'}                 // This field will use "occupation" as the mapping.
]);
var myReader = new Ext.data.XmlReader({
   totalProperty: "results", // The element which contains the total dataset size (optional)
   record: "row",           // The repeated element which contains row information
   idProperty: "id"         // The element within the row that provides an ID for the record (optional)
   messageProperty: "msg"   // The element within the response that provides a user-feedback message (optional)
}, Employee);
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
 <results>2</results>
 <row>
   <id>1</id>
   <name>Bill</name>
   <occupation>Gardener</occupation>
 </row>
 <row>
   <id>2</id>
   <name>Ben</name>
   <occupation>Horticulturalist</occupation>
 </row>
</dataset>
