GJSON Parsing Question [SOLVED]

[kryten]

Hi,

I am making heavy use of the fabulous gjson package which is taking a lot of pain away from working with Json in Go.
I’ve run up against an interesting problem though and would appreciate any thoughts or assistance with it.

I have a chunk of json:

 {
   "took": 31,
   "timed_out": false,
   "_shards": {
      "total": 70,
      "successful": 70,
      "failed": 0
   },
   "hits": {
      "total": 3709706,
      "max_score": 0,
      "hits": []
   },
   "facets": {
      "1": {
         "_type": "date_histogram",
         "entries": [
            {
               "time": 1502874000000,
               "count": 10,
               "min": 0.893,
               "max": 1.758,
               "total": 13.5977,
               "total_count": 10,
               "mean": 1.35977
            }
         ]
      }
   }
}

and I am trying to extract the “mean” value of 1.35977. With straight jsonpath, its a walk in the park using:

*.1.entries.*.mean

But I’m not able to use that in gjson. I’ve been using the test playground here:

Which is hugely helpful… but so far no pattern I’ve tried has helped. Would appreciate any assistance.

Thanks

As per usual, fight with it for hours then post here and bang… you stumble on the answer 5 mins later:

facets.*.entries.#.mean

does the trick…

thanks anyway
