Try this (for css files):

$('link[type="text/css"]').each(function(){
  var $ele = $(this);

  //check if atribute data is set and has info
  if ($ele.attr('data') !== undefined && $ele.attr('data') !== ''){ //set, so adding that info to href attribute and emptying data attribute

    $ele.attr('href', $ele.attr('data'));
    $ele.attr('data', '');

  } else{ //not set/empty, so setting/filling it and emptying href attribute

    $ele.attr('data', $ele.attr('href'));
    $ele.attr('href', '');

  }
});
