Current Level only _JSON

Is there any options for _JSON for resulting current level from nested json source ? i mean no nested result just current level. sorry my bad english.

Source :
{
   "aaa": 0,
   "bbb": 1,
   "ccc" : {
       c1: 0,
       c2: 1,
       c3: {
          c31: 0,
          c32: 1
       }
    }
}

Output expected for "var.ccc"
{
   "c1": 0,
   "c2": 1
}

Re: Current Level only _JSON

You can try the "Reduce" method.

Re: Current Level only _JSON

Sorry ab, I only find Reduce method in TDocVariantData, but the result still have nested inside.

begin
  fVar := _JSon('{"aaa":0,"bbb":1,"ccc":{c1:0,c2:1,c3:{c31:0,c32:1}}}');
  _Safe(fVar)^.Reduce(['ccc'], false, fOut);
  showmessage(fOut.tojson);
end

Result still have nested 'c3'

 {"ccc":{c1:0,c2:1,c3:{c31:0,c32:1}}}

I need a function maybe look like

showmessage(fVar.ccc.CurrentLevel);

ccc   -> {c1:0,c2:1}
root* -> {"aaa":0,"bbb":1}
c3    -> {c31:0,c32:1}

Re: Current Level only _JSON

Navigate within the TDocVariantData.Values[] properties, using _Safe() to retrieve any nested object, and only getting what you need.

Your need is so specific we perhaps won't include it within the main TDocVariantData object.
