which represents all kinds of xml nodes.

require "xml"
xml = <<-XML
<person id="1">
<firstname>Jane</firstname>
<lastname>Doe</lastname>
</person>
XML
document = XML.parse(xml) # : XML::Node
person = document.first_element_child # : XML::Node?
if person
puts person["id"] # "1" : String?
puts typeof(person.children) # XML::NodeSet
person.children.select(&.element?).each do |child| # Select only element children
puts typeof(child) # XML::Node
puts child.name # firstname : String
puts child.content # Jane : String?
