ruby - Nokogiri and finding element by name -

-

i parsing xml file using nokogiri following snippet:

doc.xpath('//root').each |root|   puts "# root found"   root.xpath('//page').each |page|     puts "## page found / #{page['id']} / #{page['name']} / #{page['width']} / #{page['height']}"     page.children.each |content|       ...     end   end end

how can parse through elements in page element? there 3 different elements: image, text , video. how can make case statement each element?

honestly, pretty close me..

doc.xpath('//root').each |root|   puts "# root found"   root.xpath('//page').each |page|     puts "## page found / #{page['id']} / #{page['name']} / #{page['width']} / #{page['height']}"     page.children.each |child|       case child.name        when 'image'             do_image_stuff        when 'text'           do_text_stuff        when 'video'           do_video_stuff        end     end   end end
