In addition to some of the other answers  you could also access the HTML element via   var htmlEl   document body parentNode    Then you could get the inner HTML content   var inner   htmlEl innerHTML    Doing so this way seems to be marginally faster   If you are just obtaining the HTML element  however  document body parentNode seems to be quite a bit faster   After you have the HTML element  you can mess with the attributes with the getAttribute and setAttribute methods   For the DOCTYPE  you could use document doctype  which was elaborated upon in this question
