Exclude storeview in hreflang generation

Question

I use this code for the href language in my head.phtml

<?php $website = Mage::app()->getWebsite()->getStores();
foreach ( $website as $store) {
    $lang = $store->getConfig('general/locale/code');
    echo '<link rel="alternate" href="' . $store->getCurrentUrl() . '" hreflang="' . $store->getCode() . '"/>' . "\n";
}?>

Which gives for all my languages the right storeview. Like:

<link rel=alternate href="http://www.mystore.nl/lifestyle.html?___store=nl&amp;___from_store=nl" hreflang=nl />
<link rel=alternate href="http://www.mystore.co.uk/lifestyle.html?___store=en&amp;___from_store=nl" hreflang=en />
etc....

Only for our app we created an extra storeview mobile. But this isn't a language and Google gives error's over this.

How can i excluded the storeview mobile in this code?

I reckon you can simply replace the following line:

echo '<link rel="alternate" href="' . $store->getCurrentUrl() . '" hreflang="' . $store->getCode() . '"/>' . "\n";

With that one (see the condition before the hreflang attribute):

if("mobile" != $store->getCode()) 
{
    echo '<link rel="alternate" href="' . $store->getCurrentUrl() . '" hreflang="' . $store->getCode() . '"/>' . "\n";
}
