def collapse_text_node(hash, element)
  value = node_to_text(element)
  if empty(value) && !element.has_attributes?
    return {}
  end

  if element.has_attributes? && !@options['noattr']
    return merge(hash, @options['contentkey'], value)
  else
    if @options['forcecontent']
      return merge(hash, @options['contentkey'], value)
    else
      return value
    end
