Nokogiri::XML::Builder.with( teste ){ |x|  
    x.exemplo "teste xml"
}
puts teste.to_xml

From what I understand, you want to use namespaces (the tags with separation). A namespace needs to be declared associated with a URI(Uniform Resource Identifier). If you need a more detailed explanation you can find at: https://imasters.com.br/artigo/161/dotnet/entendendo-namespaces/? trace=1519021197&source=single

You can create a namespace with Gem Nokogiri as an example below:

require 'nokogiri'

NAMESPACES = {
  "xmlns:ns"  => "http://www.w3.org/1999/xhtml",
  "xmlns:ns2" => "http://www.w3.org/1999/XSL/Transform"
}

ex = Nokogiri::XML::Builder.new { |xml|
  xml['ns'].exemplo(NAMESPACES) do
    xml.tagNamespace1 "Conteudo"
  end
}
puts ex.to_xml

  • I already solved this problem, but the code is correct. The interesting thing is that if you want to use the tag ns2, xml['ns2']. tagNamespace1 "Content"
