#text ⇒ Object Also known as: to_s

Returns the text of this component. Note that this flushes self.xml: subsequently if self.xml is called it will be reconstructed from this text and self.text will be flushed.

def text
  @text ||= ( remove_instance_variable(:@xml) ).to_s
end

#xml ⇒ Object

Returns a REXML::Document constructed from the text of this component. Note that this flushes self.text: subsequently if self.text is called it will be reconstructed from this XML document and self.xml will be flushed. Therefore the content of this partial is always stored either as XML or text, never both.
