Hello All,

I'm new to ROS and C++.

here's the question:

so, my yaml file looks like this:

parameters:
      status:
        stage1:
          distance: 4000
          color1:
            r: 0
            g: 255
            b: 0
          color2:
            r: 0
            g: 0
            b: 0
       stage2:
         distance: 8000
         color1:
           r: 0
           g: 0
           b: 255
         color2:
           r: 0
           g: 0
           b: 0

i want to read the struct stage1 and stage2 and their members( first status and then its member(children) like distance, color1 and color2 ) in my main.cpp. i have configured it in XmlRpc::XmlRpcValue way to read the value. at the moment i can just read parameters and its member, like:

parameters:
      distance: 4000
      color1:
        r: 0
        g: 12
        b: 0
      color2:
        r: 255
        g: 0
        b: 0

but i'm unable to read its member's member.

is it possible to read first stages and then its members(Children) like distance, color1 and color2 ? if not possible, i can maybe remove status and have just the stages.

or is there any other way to read the file where distance, color1 and color2 can be read based on their parent(like stage1 and stage2)?

Thankyou so much in Advance!!

YAML::Node root = /* ... */;
YAML::Node node = root["Node"];

// We now have a map node, so let's iterate through:
for (auto it = node.begin(); it != node.end(); ++it) {
  YAML::Node key = it->first;
  YAML::Node value = it->second;
  if (key.Type() == YAML::NodeType::Scalar) {
    // This should be true; do something here with the scalar key.
  }
  if (value.Type() == YAML::NodeType::Map) {
    // This should be true; do something here with the map.
  }
}

Node:
    Foo:
      f1 : one
      f2 : two
    Bar:
      b1 : one
      b2 : two
