我们可以在"过滤器"中使用$ sce.trustAsHtml(字符串)吗？

HTML:

  this should be replaced

JS:

    angular.module('app', []).directive('testD', ['$compile','$sce', function($compile, $sce) {
        return {
            restrict: 'E',
            link: function(scope, element, attrs, controller) {

                //"case 1"
                //var testElement = angular.element('
{{item.n}}.{{item.label}}
');

                //"case 2"
                var testElement = angular.element('
{{item.n}}
');

                scope.testClass = attrs.class;

                scope.items = [
                    //{n:10,label:$sce.trustAsHtml('label 11')},
                    // "case 1" of "testElement": no any effects (with "case 1" that would be preferred)
                    // "case 2" of "testElement": Error: [$sce:itype] Attempted to trust a non-string value in a content requiring a string: Context: html

                    {n:20,label:'label 22'},
                    {n:30,label:'label 33'}
                ];

                var testElementCompiled = $compile(testElement)(scope);

                //"case 3"
                element.replaceWith(testElementCompiled);

                //"case 4"
                //element.replaceWith($sce.trustAsHtml(testElementCompiled));
            }
        }
}]).filter('htmlize', ['$sce', function($sce){
        return function(val) {
            return $sce.trustAsHtml(val);
        };
}]);

问题:1)是否可以在过滤器上下文中使用trustAsHtml？2)如果不使用"ng-bind-html"指令,如何使用"how-to-remove-this-div"类除掉div？
