How to get node for selected node names in all file



my first scripting trials:

How can I print/get node data for each node with name ‘MyNode01’ in whole Glyphs file? This prints only this layer I guess. But any other definition I tried with my limited fantasy failed.

for node in allNodes:
	if == "MyNode01":
		print node

        Then loop over all paths of each those layers:
