outerHTML on SVGElement for IE and removing Namespaces

[renierr]

IE can not outerHTML an SVGElement.
Also it add some NS stuff if its extracted via Serializer or in my case Tag clone.

Here is an outerHTML prototype for SVGElement - should only be done in IE:

 if (!(detectIE() === false)) {
    Object.defineProperty(SVGElement.prototype, 'outerHTML', {
      get: function () {
        var $node, $temp;
        $temp = document.createElement('div');
        $node = this.cloneNode(true);
        $temp.appendChild($node);
        var ret = $temp.innerHTML;
        // cleanup for IE
        ret = ret.replace(new RegExp('NS\\d+:xmlns:xml="http://www.w3.org/XML/1998/namespace"', 'gi'), "");
        ret = ret.replace(new RegExp('NS\\d+:xmlns:ns\\d+="http://www.w3.org/XML/1998/namespace"', 'gi'), "");
        ret = ret.replace(new RegExp('xmlns:ns\\d+="http://www.w3.org/XML/1998/namespace"', 'gi'), "");
        ret = ret.replace(new RegExp('xml:', 'gi'), "");
        ret = ret.replace(new RegExp('ns\\d+:', 'gi'), "");
        ret = ret.replace(new RegExp('xmlns:xml="http://www.w3.org/XML/1998/namespace"', 'gi'), "");
        ret = ret.replace(new RegExp('NS\\d+:ns\\d+:', 'gi'), "");
        ret = ret.replace(new RegExp('xmlns:NS\\d+=""', 'gi'), "");
        return ret;
      },
      enumerable: false,
      configurable: true
    });
  }
