3、利用SuperObject 循环处理Json深层次的值

//遍历对象
procedure TForm1.Button5Click(Sender: TObject);
var
  item,jo: ISuperObject;
  ja,JA_TYPE,JA_MAC:TSuperArray;    //json数组
  i,j,k:Integer;
  jts: TSuperTableString;  //TSuperTableString 的常用属性: count、GetNames、GetValues
begin
  jo := SO(Memo1.Text);
  jts:=jo.AsObject;
  mmo1.Lines.Add('结点数:'+IntToStr(jts.count ));
  mmo1.Lines.Add('键名:'+jts.GetNames.AsString);
  mmo1.Lines.Add('键值:'+jts.GetValues.AsString);
  jts:=jo['addresses'].AsObject;
  mmo1.Lines.Add('结点数:'+IntToStr(jts.count ));
  mmo1.Lines.Add(jts.GetNames.AsString);
  mmo1.Lines.Add('键值:'+jts.GetValues.AsString);
  jts:=jo.A['children'].N[0].AsObject;
  mmo1.Lines.Add('结点数:'+IntToStr(jts.count ));
  mmo1.Lines.Add(jts.GetNames.AsString);
  mmo1.Lines.Add('键值:'+jts.GetValues.AsString);
  jts:=jo.A['children'].N[0].A['M_TYPE'].N[0].AsObject;
  mmo1.Lines.Add('结点数:'+IntToStr(jts.count ));
  mmo1.Lines.Add(jts.GetNames.AsString);
  mmo1.Lines.Add('键值:'+jts.GetValues.AsString);
  jts:=jo.A['children'].N[0].A['M_TYPE'].N[0].A['MACHINE'].N[0].AsObject;
  mmo1.Lines.Add('结点数:'+IntToStr(jts.count ));
  mmo1.Lines.Add(jts.GetNames.AsString);
  mmo1.Lines.Add('键值:'+jts.GetValues.AsString);

  ja:=jo.A['children'];  //等同 ja:=jo.O['children'].AsArray;


  for i := 0 to ja.Length-1 do
  begin

    mmo1.Lines.Add('店主:'+ja.O[i].s['name']);  //区分大小写
    JA_TYPE:=ja.O[i].O['M_TYPE'].AsArray;

    for j := 0 to ja_type.Length-1 do
    begin
      mmo1.Lines.Add('出票类型:'+IntToStr(JA_TYPE.O[j].I['MACHINE_TYPE']));
      mmo1.Lines.Add('出票类型名:'+JA_TYPE.O[j].s['MACHINE_NAME']);
      JA_MAC:=JA_TYPE.O[j].O['MACHINE'].AsArray;
      for k := 0 to ja_mac.Length-1 do
      begin
        mmo1.Lines.Add('机器编号:'+JA_MAC.O[k].s['MACHINE_NO']);
         mmo1.Lines.Add('机器状态:'+IntToStr(JA_MAC.O[k].I['STATUS']));
        mmo1.Lines.Add('机器余额:'+FloatToStr(JA_MAC.O[k].D['BALANCE']));
      end;
    end;
  end;
 // for item in jo do ShowMessage(item.AsJSon(False, False));
end;

　//Json 格式如下
