Removing specific phrases from a long string (replace function + regular expression?) In AngularJS

Question

I'm currently learning Angular. I am having trouble converting a specific long string.

So this is my div with a lot of lines generated by ng-repeat:

Yes, this is pretty unpleasant, I know. I want to remove all ng attributes and other things that I don’t need from this line, because I will pass this data to PHP through ajax.

Here is what I tried to do (angular):

    $scope.updateHtml = function() {    
    var testVal = angular.element('#sendHtml').val();
        testVal = testVal.replace(/ng-class="{'selected':selection.indexOf($index) != -1}"/g,"");
    $scope.sendHtml.html = testVal;
};

But that will not work. Perhaps it is because of the quotes inside the phrase, or is it?

This, for example, works with replacing one letter:

$scope.updateHtml = function() {
     var testVal = angular.element('#sendHtml').val();
     testVal = 'abcabcabc';
    testVal = testVal.replace(/b/g,"");
    $scope.sendHtml.html = testVal;
};

$scope.sendHtml.html 'acacac' . RegEx? , . !
