Navigating through nested nodes within an Angular directive can be achieved by

Here is some HTML code with a directive:

<foo>
    <span>Bar</span>
</foo>

myapp.directive('foo', function () {
    return {
        restrict: 'E',
        replace: true,
        transclude: true,
        template: '<div><p>{{usedToBeInSpan}}</p></div>'
    }
});

Is there a way to retrieve the content of the nested span element and assign it to the directives scope as usedToBeInSpan?

Please note that this is just a simplified example and not intended for actual use in replacing a nested tag.

To include a link function within your directive, follow the example provided below:

myapp.directive('bar', function () {
return {
    restrict: 'E',
    replace: true,
    transclude: true,
    template: '<section><p>{{nowInParagraph}}</p></section>',
    link: function (scope, element, attrs) {
           // the element parameter holds the HTML content within the directive tags <bar></bar>
          scope.nowInParagraph = "";//populate from "element"
    }
}
});

Discovered a fresh approach. In Angular, a css class is generated based on the directive's content, such as "ng-<directive>-content", allowing you to access the content of the directive within its usage. Check out this example in the following fiddle:

https://jsfiddle.net/manasisakhare/8ezh35to/2/

myapp.directive('foo', function () {
    return {
        restrict: 'E',
        //replace: true,
        transclude: true,
        template: '<div><p class="ng-foo-content" ng-transclude></p></div>'
    }
});
