First, you need to parse the source XML into a DOM object:

   require 'nokogiri'

   dom = Nokogiri::XML(File.read source_file)

Then you iterate over all InterfaceGroup nodes and modify attributes:

   dom.xpath("//InterfaceGroup").each do |node|
     node['Members'] = "some value"
   end

Finally, write the modified DOM to the target XML file:

   File.open(target_file, "w") { |f| f.write dom.to_xml }
