          case node.name
          when "h2"
            type = node.text
          when "h3"
            name = node.text.sub(/^ */, '').sub(/^await /, '').sub(/\(.*\)$/, '')
            id = node.children[0].attributes["id"].value
            entries << [name, id, type]
          when "h4"
            name = node.text.sub(/^ */, '').sub(/^await /, '').sub(/\(.*\)$/, '')
            id = node.children[0].attributes["id"].value
            entries << [name, id, type]
          end
