extracting data from deep down

[andrea-dintino]

Using this data:

{

  "cognome": "Rossi",
  "controllo_pioggia": 10,
  "dataFromEndpoint": {
    "cod": "200",
    "count": 1,
    "list": [
      {
        "clouds": {
          "all": 20
        },
        "coord": {
          "lat": 43.7667,
          "lon": 11.25
        },

        },

        "sys": {
          "country": "IT"
        },
        "weather": [
          {
            "description": "few clouds",
            "icon": "02d",
            "id": 801,
            "main": "Clouds"
          }
        ],
        "wind": {
          "deg": 0,
          "speed": 2.06
        }
      }
    ],
    "message": "accurate"
  },

  "nameOfNewObject": "HELLO_WORLD!",

}

I want to perform transformations on "main" inside "weather" inside "list" inside "dataFromEndpoint".

Can be implemented with a walk / pointer system

[jaromil]

When I create the pointer to 'dataFromEndpoint'
and I push the pointer in `list`
and I push  the pointer in `main`

# move something inside the table referenced by pointer
When I move 'myData' in pointer
When I copy 'myData' in pointer

# exctract to the root something inside the table referenced by pointer
When I extract 'feels_like' from pointer

[jaromil]

When I set the pointer to 'dataFromEndpoint'
and I enter `list` with pointer
and I enter `main` with pointer

# move something inside the table referenced by pointer
When I copy 'myData' to pointer

# exctract to the root something inside the table referenced by pointer
When I create the copy of 'feels_like' in pointer
and I delete 'feels like' in pointer
