Yes.

One way is to implement VrmlNodeVisitor. Look in VrmlNamespace.cpp at
VrmlNodeCloneVisitor for an example.

Unfortunately, we don't yet have a good way for traversing the scene
graph without knowing anything about the node types. I'm planning on
adding a getChildren() method to the VrmlNode interface, which should
help with this.
