disabling view with in action in ZF2

Question

I am struggling with disabling view in ZF2 $this->_helper->viewRenderer->setNoRender(); or (true) with no luck as it always says there

Answer 1

public function indexAction() {

    $news = $this->em->getRepository('Admin\Model\News');
    foreach ($news->findAll() as $new) {


        $res = $this->getResponse()->setContent($new->toXml());
    }





    return $res;

}
