I would like to access a root file and do a listing of the objects (trees in particular) that are inside.
In particular I want to open a (or more than one) tree inside the root file without having to know the tree name previously. And once I have the tree I would like to list the branch names (and types) that are inside that tree.
I would like to do this in order to access a ROOT file in a more generic way.
Thanks in advance,
