Can I read from an YAML file that contains multiple nested structs with arrays?

I tried to load YAML from file and only the root Image is loaded, but the Clothes array is not. Is this a limitation of the plugin or I just did some error in my loader/processing?

Example below, can I read this into a Cloth struct that has an array of ClothDetails?

Image: Clothes.png
Clothes:
    - Cloth:
        Type: Hat
        Image: hat.png
    - Cloth:
        Type: Shoes
        Image: shoes.png
    - Cloth:
        Type: Pants
        Image: pants.png
    - Cloth:
        Type: Gloves
        Image: gloves.png

I had my structs as:

USTRUCT(BlueprintType)
struct MYPROJECT_API FClothDetailsStruct {
    GENERATED_BODY()

    UPROPERTY(BlueprintReadWrite)
    FString ClothType;

    UPROPERTY(BlueprintReadWrite)
    FString Image;

};


USTRUCT(BlueprintType)
struct MYPROJECT_API FClothStruct {
    GENERATED_BODY()

    UPROPERTY(BlueprintReadWrite)
    FString Image;

    UPROPERTY(BlueprintReadWrite)
    TArray<FClothDetailsStruct> Clothes;

};

Can you give a test project in Unreal or a short test code, which will be very helpful for beginners.

Thank you very much for your contribution.

Currently if you want to have access to the keys while iterating, you can't use ranged-based for loops, but because there is no const iterator (like yaml-cpp), you end up having to copy the node. Example:

auto next = node["next"];
for(auto it = next.begin(); it != next.end(); ++it)
{
	auto key = it.Key().As<FString>();
        // ...
}
