I'm not familiar with how your XML file is organized but I assume the problem is that there are 4+ nodes with the same name, of which you only want 2. When I ran into a similar situation I set a flag for myself after the last node that I wanted, so I never read anything else.
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.
