使用条件过滤删除对象 - Mule 3

问题描述

我需要使用 Mule 3 进行条件过滤。下面给出了一个示例负载：

{
  "MainNode": {
    "ID": "123","MainNodekey1": "1","sysDetail": [
      {
        "sysDetail11": "localhost1","sysDetail21": "443","country": [
          {
            "k1": "country","value": [
              "IN"
            ]
          }
        ]
      },{
        "sysDetail21": "localhost2","sysDetail22": "443","country": [
          {
            "k2": "country","value": [
              "RSA","UK","SL"
            ]
          }
        ]
      }
    ],"sysDetai2": {},"sysDetai3": {}
  },"MainCode": "AAA","MainTyoe": "BBB","MyArray": [
    {
      "ObjId": "100","Obj1": {
        "SubObj11": {},"SubObj12": {},"ObjCountry": "IN","ObjId": "A100"
      },"Obj1Source": {}
    },{
      "ObjId": "200","Obj2": {
        "SubObj21": {},"SubObj22": {},"ObjId": "B100"
      },"Obj2Source": {}
    }
  ]
}

我需要的输出是通过应用如下过滤器来过滤主要负载： payload.MainNode.sysDetail.country..value == payload.Obj1.ObjCountry（对于所有数组元素都是常量）

预期输出如下：

{
  "MainNode": {
    "ID": "123","value": [
              "IN"
            ]
          }
        ]
      }
    ],"Obj2Source": {}
    }
  ]
}
