That's your best bet if you want to map strings to NodePtrs.
The above function should help you, just do the following instead of cout:
map.insert(std::make_pair(std::string(getName(node)), node));
(Where map is a variable of type std::map<std::string, OSG::NodePtr>)

No general search for nodes, AFAIK.
I have written my own that traverses a graph and looks for a node based
on names, but if your nodes (and their names) do not change, it is
better to create the map just once.
Note that several nodes can have the same name. There is an integer ID
for each FieldContainer (which is what Node is) and that is unique, so
it might help you if you run into trouble.
