yii对象dataProvider的读取信息问题

public function actionIndex()
{
$dataProvider=Export::model()->findAllBySql("select id,BaiduLat,BaiduLon from tablename where id
$this->render('index',array(
'dataProvider'=>$dataProvider,
));
}
这是控制器中的方法，现在想在index.php把$dataProvider的数据给读取出来，放在数组里。 print_r($dataProvider)； 输出得到以下，

Array ( [0] => Export Object ( [_new:CActiveRecord:private] => [_attributes:CActiveRecord:private] => Array ( [id] => 1 [BaiduLat] => 31.262788 [BaiduLon] => 121.630306 ) [_related:CActiveRecord:private] => Array ( ) [_c:CActiveRecord:private] => [_pk:CActiveRecord:private] => 1 [_alias:CActiveRecord:private] => t [_errors:CModel:private] => Array ( ) [_validators:CModel:private] => [_scenario:CModel:private] => update [_e:CComponent:private] => [_m:CComponent:private] => ) [1] => Export Object ( [_new:CActiveRecord:private] => [_attributes:CActiveRecord:private] => Array ( [id] => 2 [BaiduLat] => 31.263184 [BaiduLon] => 121.630395 ) [_related:CActiveRecord:private] => Array ( ) [_c:CActiveRecord:private] => [_pk:CActiveRecord:private] => 2 [_alias:CActiveRecord:private] => t [_errors:CModel:private] => Array ( ) [_validators:CModel:private] => [_scenario:CModel:private] => update [_e:CComponent:private] => [_m:CComponent:private] => ) )

print_r($dataProvider)；得到上面这些东西，请问，如何把多个BaiduLat和BaiduLon的信息给取出来，放在一个数组中，便于后续地图标注使用，谢谢

回复讨论(解决方案)

所有的成员都是 private （私有）的，在外部不能访问
所以 Export 类一定存在有处理这些私有成员的方法，你可以仿写一下
