defmodule Meeseeks.TupleTree do

  @moduledoc """

  HTML documents in Elixir/Erlang have traditionally been represented by a

  tuple-tree like:



  ```elixir

  {"html", [], [

    {"head", [], []}

    {"body", [], [

      {"h1", [{"id", "greeting"}], ["Hello, World!"]}]}]}

  ```



  `:mochiweb_html` parsed HTML into this format, and the tools for selecting

  HTML used this format, so `html5ever` (the Elixir NIF) choose to output

  to this format as well.



  Meeseeks accepts tuple-trees as input, creating `Meeseeks.Document`s from

  them.
