The problem is that you have found a NavigableString not the td . Also nextSibling will find the next NavigableString or Tag so even if you had the td it wouldn't work the way you expect.
You can use findChildren pretty easily to iterate over the td's in a table, assuming it's in a table. You could find the table first, ideally.
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.
