"Write Operator XML"

carbourator

Hello

I am using RapidMiner to create complex and deep object consisting of multiple other obejcts, some of which are provided by RapidMiner, and others were created by me. I need to perform querries over this structure, but it seems quite complicated. I tried to use serialization using Write Object operator, but the resulting XML schema has too much unwanted layers, which makes querring almost impossible. Is there a way how to influence XML produced by Write Object operator?
I know RapidMiner doesnt allow complex objects being stored to database, so can you think of any other way how to achieve this?
Using ORM would probably be possible, but I believe there are requirements about classes being annotated in order to store them, which I cant do because I use some native RapidMiner classes.

Thank you
