We ask the user here to define html, so add a div or a section or something like that. So, I want the validation-tooltips when editing my HTML. But don't wanna have the doc-type warning.

• html
• ace-editor

• As stated in this thread, it doesn't seem to be possible to filter certain errors, though you can disable them all. – Jelle De Loecker Commented Oct 20, 2015 at 14:52

Try this

var session = editor.getSession();
session.on("changeAnnotation", function() {
  var annotations = session.getAnnotations()||[], i = len = annotations.length;
  while (i--) {
    if(/doctype first\. Expected/.test(annotations[i].text)) {
      annotations.splice(i, 1);
    }
  }
  if(len>annotations.length) {
    session.setAnnotations(annotations);
  }
});

With "Unexpected End of File. Expected DOCTYPE." warning filtered.

var session = editor.getSession();
session.on("changeAnnotation", function () {
    var annotations = session.getAnnotations() || [], i = len = annotations.length;
    while (i--) {
        if (/doctype first\. Expected/.test(annotations[i].text)) {
            annotations.splice(i, 1);
        }
        else if (/Unexpected End of file\. Expected/.test(annotations[i].text)) {
            annotations.splice(i, 1);
        }
    }
    if (len > annotations.length) {
        session.setAnnotations(annotations);
    }
});

If instead you operate on the annotations directly and call the editor onChangeAnnotation method directly to update the annotations on the page you can prevent firing another changeAnnotation event and calling this event handler twice as Chris's answer does.

var editor = Application.ace.edit(element),
    session = editor.getSession();

session.on('changeAnnotation', function () {
  session.$annotations = session.$annotations.filter(function(annotation){
    return !(/doctype first\. Expected/.test(annotation.text) || /Unexpected End of file\. Expected/.test(annotation.text))
  });
  editor.$onChangeAnnotation();
});
