How to remove angularjs attributes and classes from HTML?

I have a simple AngularJS app that renders a parent element containing some nested elements from a template using ng-bind and ng-repeat. I would like to grab the HTML (innerHtml) of the generated element (as a string) for usage in a different application (where it is to be used as static HTML, outside the context of AngularJS).

This is easy enough to do by using jQuery('#parent-element').html(). The problem with this approach is that the HTML string contains Angular attributes (for example ng-bind) as well as Angular generated comments (from ng-repeat) and classes (such as ng-scope).

I can probably come up with some regular expression to clean up all of these from the string directly, but I would love to know if there is a cleaner way to do this.

So, is there a more "Angular" way to either prevent the attributes/classes/comments from being generated or to extract a clean version of the source HTML of the generated elements?

UPDATE: For @suhas-united and others who might find this useful, I ended up using the following which works well enough for my use case-

var cleaner = angular.element('#dirtier')
            .html()
            .replace(/<!--[^>]*-->/gi, '')
            .replace(/\n/g, '')
            .replace(/ng-.+?\b/g, '')
            .replace(/ng-.+?=".*?"/g, '')
            .replace(/class=""/g, '')
            .replace(/\"/g, "\\\"")
            .replace(/\s+/g, " ");

I found a soultion:

    var x = angular.element('#id').html()
        .replace(/(ng-\w+-\w+="(.|\n)*?"|ng-\w+="(.|\n)*?"|ng-(\w+-\w+)|ng-(\w+))/g, '')
        .replace(/<!--(.*?)-->/gm, "")

It clears any "ng-" directives and "ng-" classes!

    /*replace value of attrs*/    .replace(/="(.*?)"/gm, "")
    /*replace html markup */ .replace( /<[\s\S]*?>/g, "")
    /*replace whitespaces */  .replace(/\s/g, '')

If you don't have a very large number of ng- attributes, you could try something like this:

var div = $("#mydiv");
div.removeAttr("ng-repeat").removeAttr("ng-bind")....

If you have a large number of them, see Get all Attributes from a HTML element with Javascript/jQuery and you could add a method 

div.removeAllAttr("ng-")
