Wiki contains no examples of how to retrieve anchors.

I would very much like to see an example of how one would retrieve anchors from YAML::Node's.

Thank you.

#include <iostream>
#include "yaml-cpp/yaml.h"

int main() {
    // Parse the YAML document
    YAML::Node doc = YAML::LoadFile("example.yaml");

    // Access the 'fruits' node
    YAML::Node fruits = doc["fruits"];

    // Iterate through the elements in 'fruits' to retrieve anchors
    for (const YAML::Node& fruit : fruits) {
        if (fruit.IsScalar()) {
            // Check if the node is a scalar (e.g., Red, Yellow)
            std::cout << "Scalar Value: " << fruit.as<std::string>() << std::endl;
        } else if (fruit.IsAnchor()) {
            // Check if the node is an anchor reference
            std::cout << "Anchor Name: " << fruit.as<std::string>() << std::endl;
        }
    }

    return 0;
