The error message means that there is either 0 or multiple nodes that
match dom.book.@title. By replacing ${dom.book.@title} with
${dom.book.@title?size}, you will certainly find it prints 0. Then you
can go ahead and try if ${dom.book?size} is 0 too, means you don't
have a the book element either... things like that.
