Excellent!! Thank you. I was missing select_single_node and &b ;)
Wrapper is now sorted, and I can do:
require 'xml'
@document =
Document.new('<x><x1><z>test</z><y><q>abc</q></y></x1><x1><z>tester</z><a>testeraaa</a></x1></x>')
@document.elements('x/x1') do |e|
puts e.get('z')
e.node('y') {|y| puts y.get('q')}
end
Thanks
Ben
