Route requests for sitemap.xml to custom controller/action

In order to direct requests for /sitemap.xml to a custom controller and action in your Zend Framework application simply add the following in your application.ini or alternative config file (e.g. I use navigation.ini):

resources.router.routes.sitemap.route                = "sitemap.xml"
resources.router.routes.sitemap.defaults.controller  = index
resources.router.routes.sitemap.defaults.action      = sitemap

Example code for outputting can be seen by creating an action in the appropriate controller (e.g. my sitemap lies in the index controller, sitemap action):

<php
class IndexController 
    extends Zend_Controller_Action
{
    /**
     * Renders a sitemap based on Zend_Navigation setup
     */
    public function sitemapAction()
    {
    	echo $this->view->navigation()->sitemap();
    	$this->view->layout()->disableLayout();
    	$this->_helper->viewRenderer->setNoRender(true);
    }
}

Sitemaps can quickly and easily be generated using Zend_Navigation, a great quick tutorial (and generally very useful for Zend Framework tutorials) is Zend Casts – Dynamically creating a menu a sitemap and breadcrumbs.
