How to parse JSON array from inside an object with rapidjson

Solution 1:

doc['layers'] is an array.

const rapidjson::Value& layers = doc["layers"];
assert(layers.IsArray()); 

for (size_t i=0; i < layers.Size(); i++) {
  const rapidjson::Value& data = doc["layers"][i]["data"];
  assert(data.IsArray());
}

UPDATE:

Direct access to first data item in layers:

const rapidjson::Value& data = doc["layers"][0]["data"];

This only gives you the data for the first item in layers array. If layers have at least one item and you only need the first one, then this will always work.
