selector =  "//td[text()='%s']/following-sibling::td"

os_hook =  Proc.new do |element|
             element.inner_html.split('<br>').each do |datum|
               datum.strip!.upcase!
             end
           end


scraper = Ninja2k::Scraper.new(url, selector, :clues => clues, :hooks => { 'Operating system' => os_hook })

package = scraper.to_xlsx
