That might work, I just don't see the flow yet... I have a xml file in the folder where the data is which I read using my custom data class. So it is living as a property of the class. Is that not the intended use case? I was going to use https://kedro.readthedocs.io/en/latest/06_nodes_and_pipelines/03_modular_pipelines.html, Does this make any sense? prep_pipeline = pipeline(pipe=cook_pipeline, inputs={"food": "grilled_veg", "param1": my_classname.xmldata})
