Answer 2

var values = s.Elements("chapter").Select(n => n.Value).ToArray();

Furthermore, you're reading from the same element (booknumber) over and over. You might want to check your code.

EDIT: to also yield the attribute:

s.Elements("chapter").
Select(n => new {Topic = n.Attribute("topic").Value, Value = n.Value}).
ToArray();
