Help needed in converting string representation of protobuf to JSON/XML

[Kousalya Mathiyazhagun]

Hi Team,

I am getting a gNMI subscribe response in str representation of protobuf. I want to create a entity with this data based on YDK models.

Could you please help me in converting below data to pure JSON removing all update/elem/path hierarchy.

Sample data:

update {
  timestamp: 1569824857471000000
  prefix {
    origin: "openconfig-interfaces"
    elem {
      name: "interfaces"
    }
  }
  update {
    path {
      elem {
        name: "interface"
        key {
          key: "name"
          value: "FourHundredGigE0/0/0/0"
        }
      }
      elem {
        name: "state"
      }
      elem {
        name: "counters"
      }
      elem {
        name: "in-octets"
      }
    }
    val {
      uint_val: 0
    }
  }
  update {
    path {
      elem {
        name: "interface"
        key {
          key: "name"
          value: "FourHundredGigE0/0/0/0"
        }
      }
      elem {
        name: "state"
      }
      elem {
        name: "counters"
      }
      elem {
        name: "out-octets"
      }
    }
    val {
      uint_val: 0
    }
  }
  update {
    path {
      elem {
        name: "interface"
        key {
          key: "name"
          value: "FourHundredGigE0/0/0/0"
        }
      }
