解析字符串化XML的多个属性

Question

下面是XML.I想要解析并获取id。但是想要那些具有INT值的ID。在下面的XML中有四个Ids标签。我想要那些没有valus作为n / a。

{
  "status": {
    "runStatus": "STOPPED"
  },
  "component": {
    "state": "STOPPED",
    "id": "9204b68d-0159-1000-7d8f-720592b2a2dd"
  },
  "id": "9204b68d-0159-1000-7d8f-720592b2a2dd",
  "revision": {
    "version": 10,
    "clientId": "ab010dd6-0159-1000-615b-f095502a7ceb"
  }
} 

我正在以这种方式解析xml并在设备响应中设置值（这是bean类）
