I would say implementing "beans" that are logically sound with your flow logic, then have a mapper maps the XML to the beans (create beans base on the XML). This way you decouple your flow logics from the XML file format, so later on if you decide to use JSON or the XML file format changes, all you have to do is to change the mapper.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
