If the yaml looks like

sensors:

How to get the name of the sequence from the node ? Using the sensors node how can i get the names of id1 and id2 ?

Answer 1

Just iterate through the node; you get key/value pairs:

for (const auto& kv : node["sensors"]) {
  kv.first.as<std::string>();  // "id1" or "id2"
}
