Javascript for stripping tags?

Thanks to my weird way of using the new Reminders integration, the Preference box for stripping extra tags when archiving done tasks doesn’t work for me. I have a Javascript code that I use to add tags for @done @due(time i completed the task) so when I import the task into reminders, it’s marked with the time I completed the task.

What line of code would I add to strip the item of all tags except for @done and @due ? (Alternately, would it be possible to have a preference option to strip tags when importing to Reminders?)

The code I’m using

function TaskPaperContextScript(editor, options) {

  function setAttribute(editor, items, name, value) {
    var outline = editor.outline;
    var selection = editor.selection;	
    outline.groupUndoAndChanges(function() {
      items.forEach(function (each) {
        each.setAttribute(name, value);
      });
    });	
    editor.moveSelectionToItems(selection);
  }

  function toggleAttribute(editor, items, name, value) {
    items.forEach(function (each) {
      if (each.hasAttribute(name)) {
        value = null; // If any item has the attribute, then remove it from all.
      }
    });
    setAttribute(editor, items, name, value);
  }

toggleAttribute(editor, editor.selection.selectedItems, 'data-due', DateTime.format('this minute'));
  toggleAttribute(editor, editor.selection.selectedItems, 'data-done','');
}

Application("TaskPaper").documents[0].evaluate({
  script: TaskPaperContextScript.toString()
});

Thanks!

Never mind — I just saw the menu option to strip tags, I can incorporate that into my keyboard maestro macro. Thanks!
