Given

<mytag class="red">
     <mysubtag id="3"></mysubtag>
</mysubtag> 

subtag might have different meanings depending on the parent tag (it might be mytag or mysupercustomtag). I have directives for all parent tags. How can I access the subtags?

I know in the link function of the directive for mytag I can use children(), contents(), and data(), and even elm.find('#someid'). Would something like the following do the trick? What's the correct way of doing that? nested directives?

.directive('mytag', function() {
  return {
    restrict: 'A',
    template: '<div></div>',
    replace: true,
    link: function (scope, element, attrs) {
        // get the id of the first child (for example mysubtag)
        var newid = element.children()[0].getAttribute('id');
        // and put it in mytag, so that it is transformed into <div class="red" id="3">..
        attrs.$set('id', newid);
    }
  } 
})

• I think as per angularjs, parents are not suppose to know about children – Arun P Johny Commented Apr 17, 2013 at 11:32
• 1 By the time the linking function runs, mysubtag is gone, since your directive has a template and uses replace: true. – Mark Rajcok Commented Apr 17, 2013 at 15:50

This approach is not correct . For Nested directives you have to declare controller in parent directive and use require attribute in child directive to access parent controller.Please see below example from angular documentation for child parent directives. Below link will help you to set up one
