Hi Francesco, You just need to write a NodeVisitor that traverses through the scene and detects the osg::Switch and osgSim::DOFTransform. The NodeVisitor has an apply(osg::Switch&) method, but not a DOFTransform one so you'll need to implement and apply(osg::Transform&) and then dynamic_cast this to a DOFTransform to find out whether the transform is a DOFTransform.
There are many examples of subclasses from NodeVisitor and their usage in the OSG sources, as well as the tutorials so review these for further guidance on what custom NodeVisitor look like. Robert.
