使用Zend Framework输出xml方法

Zend Framework 输出xml的几种方法。见代码：

1.

class TestController extends Zend_Controller_Action {
    /**
     * The default action - show the home page
     */
    public function indexAction() {
        $content = "<?xml version='1.0'?><foo>bar</foo>";
        header('Content-Type: text/xml');
        echo $content;
        exit;
    }
}

加一句exit;这样可以不用关闭view.

2.

class TestController extends Zend_Controller_Action {
    /**
     * The default action - show the home page
     */
    public function indexAction() {
     // XML-related routine
        $xml = new DOMDocument('1.0', 'utf-8');
        $xml->appendChild($xml->createElement('foo', 'bar'));
        $output = $xml->saveXML();
        // Both layout and view renderer should be disabled
        Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer')->setNoRender(true);
        Zend_Layout::getMvcInstance()->disableLayout();

        // Setting up headers and body
        $this->_response->setHeader('Content-Type', 'text/xml; charset=utf-8')
                ->setBody($output);
    }

}

第二种方法可以调用DOMDocument对象来创建更丰富的xml.
