获取后台返回数据

以添加数据为例：
后台：
         返回数据时如=======》
                         render(contentType: 'text/xml') {
                         items{
                                   item{
                                       message("success")
                                        }
                                }
                             }
前台：保存数据==========》
                         postForm.saveData(new DSCallback() {
    
                 public void execute(DSResponse response, Object rawData, DSRequest request) {
                                  Record[] records=response.getData();=======================》取得返回记录，得到一个数组
                                if(records.length>=1){
                                    String message=records[0].getAttribute("message");
                                    if(message.equals("success")){
                                        SC.say("提示", "保存成功！");
                                    }else{
                                        SC.say("提示", "保存失败！");
                                     }
                              }
                         }
                   });
注意：返回数据的路径与dataSource的路径一到致，
如：
items{
   item{}
}
它与dataSource设置setRecordXPath("/items/item")的路径一致
