在将Json转换为xml时如何忽略某些xml节点？

Question

我的Json输入如下：

{
    education_level_id: 0
    country_id: 2
    education_level: "PG"
    delete_flag: false
    insert_by: null
    insert_date: "2015-10-19 12:49:52.0"
    update_by: null
    update_date: "2015-10-19 12:49:52.0"
}

我的实际XML就像：

{"PickerInput":{"Pick":[{"@name":"L0C4R0"},{"@name":"L0C0R0"},{"@name":"L0C3R0"}]}}

我的EXPECT XML就像：

<PickerInput>**<Pick>**<Pick name="L0C4R0"></Pick><Pick name="L0C0R0"></Pick><Pick name="L0C3R0"></Pick>**</Pick>**</PickerInput>

**问题：**如何在XML中删除包装的Pick节点？提前感谢。

我的班级定义：

<PickerInput><Pick name="L0C4R0"></Pick><Pick name="L0C0R0"></Pick><Pick name="L0C3R0"></Pick></PickerInput>
