Angular-根据条件从JSON对象获取值

Question

我想根据条件从JSON对象获取值。

例如： 我有以下JSON对象。

{
  "text": "India",
  "value": 1,
  "locationCode": "001",
  "children": [
    {
      "text": "Karnataka",
      "value": 37,
      "locationCode": "EX01",
      "disabled": "false",
      "children": [
        {
          "text": "Hubli",
          "value": 38,
          "disabled": "false",
          "locationCode": "UBL01",
          "children": [
            {
              "text": "Vidyanagar",
              "value": 43,
              "disabled": "false",
              "locationCode": "VID01",
              "children": []
            }
          ]
        },
        {
          "text": "Bangalore",
          "value": 40,
          "disabled": "false",
          "locationCode": "BANG01",
          "children": [
            {
              "text": "JayNagar",
              "value": 48,
              "disabled": "false",
              "locationCode": "JAY000",
              "children": [
                {
                  "text": "Vidyagiri",
                  "value": 56,
                  "disabled": "false",
                  "locationCode": "VID001",
                  "children": []
                }
              ]
            }
          ]
        },
        {
          "text": "Mysore",
          "value": 57,
          "disabled": "false",
          "locationCode": "CG002",
          "children": []
        }
      ]
    }
  ]
}

我要通过此JSON传递一个位置名称，并获取父（祖父母）和孩子 （外孙）的位置。

例如：如果我通过Bangalore location，那么我应该获得以下JSON响应：

{
  "text": "India",
  "value": 1,
  "locationCode": "001",
  "children": [
    {
      "text": "Karnataka",
      "value": 37,
      "locationCode": "EX01",
      "disabled": "false",
      "children": [
        {
          "text": "Bangalore",
          "value": 40,
          "disabled": "false",
          "locationCode": "BANG01",
          "children": [
            {
              "text": "JayNagar",
              "value": 48,
              "disabled": "false",
              "locationCode": "JAY000",
              "children": [
                {
                  "text": "Vidyagiri",
                  "value": 56,
                  "disabled": "false",
                  "locationCode": "VID001",
                  "children": []
                }
              ]
            }
          ]
        }
      ]
    }
  ]
}

作为回应应该给班加罗尔所在地的父母（祖父母）和孩子（孙子女）。

如何实现？

有人可以为此提供解决方案吗？
