AngularJs: Extracting a string from compiled HTML or a variable

My goal is to retrieve a string from a template that I can later edit using Textangular or save in a database. This template comes from the server and is stored in the database.

    TemplateMailService.get($scope.type, function (data, status) {


            $scope.template = data.template;
            
            $timeout(function () {

                data.template.content = $compile(data.template.content)($scope);

                $log.debug('$scope.mail.content : ', $scope.mail.content);
                $log.debug('data.template.content : ', angular.element(data.template.content));
                
                var string = '';
                string += data.template.content[0].innerHTML;

                console.log(string);

                $scope.mail.content = string;
            }, 0);

    })

I aim to save the compiled template with all the ng-xx attributes and {{ variables }} applied as a string so that I can edit it in textangular.

I understand that this could be achieved by using a directive, but I'm not sure how to return the compiled template in a string form.

What am I overlooking here?

Thanks.

$evaluate

When you need to assess individual expressions such as {{value}} within your content.data[0].innerHTML; string, consider using $evaluate.

$render

For generating the final compiled output, $render might be the key, as it handles strings with dynamic expressions like

<div ng-show='isActive'>Hi there {{userName}}</div>
