Support recursive descent JsonPath syntax (and lens)

[johnspaul]

Hi ,

I have a scenario in my application , where i have to recusrively get all the data, and i tried to use the jsonPath $.store.book[*].subBooks[*]..author as mentioned in http://goessner.net/articles/JsonPath/ . But i am getting an error while parsing. I tested the same using some online parsers and it is working fine. I would like to know if this is the right syntax to be used in JsonLenses. Please let me know if am missing some thing.

{ 
"store": {
    "book": [
      { "category": "reference",
        "author": "Nigel Rees",
        "title": "Sayings of the Century",
        "price": 8.95,
        "subBooks": [
          { "category": "fiction",
            "author": "Evelyn Waugh",
            "title": "Sword of Honour",
            "price": 12.99,
            "isbn": "0-553-21311-3",
            "subBooks": [
          { "category": "fiction",
            "author": "Evelyn Waugh",
            "title": "Sword of Honour",
            "price": 12.99,
            "isbn": "0-553-21311-3"
          }
        ]
          }
        ]
      },
      { "category": "fiction",
        "author": "Evelyn Waugh",
        "title": "Sword of Honour",
        "price": 12.99,
        "isbn": "0-553-21311-3"
      }

    ],
    "bicycle": {
      "color": "red",
      "price": 19.95
    }
  }
}

Hi @johnspaul, yes that's correct, recursive decent is currently not supported. IIRC neither in json path nor in json-lenses themselves.
