Represents a tagged XML element. Elements are characterized by having children, attributes, and names, and can themselves be children.
Create a new element.
# File rexml/light/node.rb, line 20 def initialize node=nil @node = node if node.kind_of? String node = [ :text, node ] elsif node.nil? node = [ :document, nil, nil ] elsif node[0] == :start_element node[0] = :element elsif node[0] == :start_doctype node[0] = :doctype elsif node[0] == :start_document node[0] = :document end end
Append a child to this element, optionally under a provided namespace. The namespace argument is ignored if the element argument is an Element object. Otherwise, the element argument is a string, the namespace (if provided) is the namespace the element is created in.
