    <child1 foo="abc" noko:bar="def"/>
  </root>
XML

attributes = doc.root.elements.first.attribute_nodes
# => [#(Attr:0x35c { name = "foo", value = "abc" }),
#     #(Attr:0x370 {
#       name = "bar",
#       namespace = #(Namespace:0x384 {

#         href = "http://nokogiri.org/ns/noko"
#         }),
#       value = "def"
#       })]

attributes.first.deconstruct_keys([:name, :value, :namespace])
# => {:name=>"foo", :value=>"abc", :namespace=>nil}

attributes.last.deconstruct_keys([:name, :value, :namespace])
# => {:name=>"bar",
