Constructor Details

#initialize(argument = '') ⇒ TextNode

TextNodes quack like a string. def_delegators :to_s, *String.instance_methods(false).reject do |m|

m.to_s =~ /^\W|!$|(?:^(?:hash|eql?|to_s|length|size|inspect)$)/

end

String.instance_methods(false).select { |m| m.to_s =~ /!$/ }.each do |m|

define_method(m) do
  content.send(m) if content.respond_to?(m)
end

end
