var nodeA = sceneA.instance()

how can I check whether the nodeA is an instance of sceneA?

if nodeA.get_filename() == sceneA.get_path():

That should do it, calling get_filename() on an instantiated scene’s root node returns the path to the scene file by default.

If you want to check child nodes as well, use get_owner(), which in effect returns the root node when called on child nodes or null otherwise:

var root
if nodeA.get_owner():
    root = nodeA.get_owner()
else:
    root = nodeA
if root.get_filename() == sceneA.get_path():

Ok, I´m not sure of that, but probably is a valid case to “extends” keyword (or “is” in godot 3.0) . Can you try?:

if nodeA extends sceneA: 
  print ("it works")

Never use extends for that, but who knows.

unable to do that as PackedScene is not a class. It will give error more less like this : right operand of the 'is' is not a class
