Geting uv scale reference from a shell or shape node

Hi,

I want to write a python script that parses a scene and generates a csv of all the shape and shell node uv scales. i also want it to display the shell name and the hierarchy path. the problem i have is i don’t know what the command’s to achieve this. i.e. the command for selecting a shell node, the command to pick the scale reference of the selected shell etc.

is there a list somewhere i can reference that gives me the scripting names or commands?

thank you
Simon
