Seems like a bug. You should report it to http://htmlagilitypack.codeplex.com .
Managed to do another way of workaround this problem. This works slightly better in my case than the one above. Basically we are replacing the first child of the DocumentNode, which is the xml declaration.(please note that the input must contain the xml declaration, in my case it's 100%).
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.
