#add_child_node_and_reparent_attrs(node) ⇒ Object

HTML elements can have attributes that contain colons. Nokogiri::XML::Node#[]= treats names with colons as a prefixed QName and tries to create an attribute in a namespace. This is especially annoying with attribute names like xml:lang since libxml2 will actually create the xml namespace if it doesn’t exist already.
