access nested JSON object with random or unknown name on karate framework

Question

I have this piece of JSON response

"A": {
"RandomName01": {
    "B": "BOS",
    "C": {
        "RandomName02": {
            "D": "32",
            "E": "ABC",
            "F": "DEF"
        }
    },
    "G": "GHI"
}

I need to extract value of D from it, having two RandomName tags on the way. I can't find anything in documentation related to handling unknown names. I tried using [], *, [0], .. etc but I failed.

For example:

def value = response.A..C..D
def value = response[0].C[0].D

etc...

Thanks,

Thanks for help. Your answer has made me try jsonPath in karate

This has made a trick:

* def value = karate.jsonPath(response, "$..D")

To try jsonPath I used: http://jsonpath.com/

For jsonPath expressions I used: https://goessner.net/articles/JsonPath/index.html#e2

Thanks :)

This should work,

* def value = response..["D"]

you can deepscan any key using .. operator

karate uses jsonpath for JSON manipulation.

Please refer Json path operators for more useful information.
