Boost 1.46.1, Property Tree: How to iterate through ptree receiving sub ptrees?

Question

First of all I shall say that I think I got how it should be done but my code will not compile any way I try. I based my assumption on this official example of empty ptree t

Answer 1

Using C++11, you can use the following to iterate through all the children of the node at path:

ptree children = pt.get_child(path);
for (const auto& kv : children) {
    // kv is of type ptree::value_type
    // kv.first is the name of the child
    // kv.second is the child tree
}
