How to apply Bindy Data conversion on Multiple classes/ Apply bindy on factory classes

Question

I have pipe delimited data, which I want to transform that into xml. That transformation needs to be done based on the content of pipe delimited data. I'm trying to apply factory design pattern to design my model classes.It is throwing following errors.

what is the best way to solve the problem for the content based transformation.
