A nested hierarchy or inclusion hierarchy is a hierarchical ordering of nested sets. The concept of nesting is exemplified in Russian matryoshka dolls. Each doll is encompassed by another doll, all the way to the outer doll.
I have a xml sample structure like below Discovery. I am trying to generate this XML structure. It seems i can manage that with visitor pattern but since structure contains nodes, visitor patttern seems not enough. I stumbled upon hierarchical visitor at but i could not manage to create a sample. My priority is reduce if-else or switch statements.
So is there any sample implementation with C# about hierarchical visitor or simple explanation with complete sample?
