hreflang tags for multiple websites?

Question

I have three websites under single magento installation and would like to generate hreflang tags for each websites manually.

I used the code mentioned in this question

<?php foreach (Mage::app()->getWebsites() as $website) {
    foreach ($website->getGroups() as $group) {
        $stores = $group->getStores();
        foreach ($stores as $store) {
            $storeCode = substr(Mage::getStoreConfig('general/locale/code', $store->getId()),0,2);
            echo '<link rel="alternate" hreflang="' . $storeCode . '" href="' . $store->getCurrentUrl(false) . '"/>' . "\n";
        }
    }
}
?>

However, this only outputs hreflang available as storeview language. Also no coutntry is specified. I would like to use more hreflang tags as fi,de, en-ca etc.

How can I manually write hreflang tag?

--- UPDATE ---

For now, I could manually write hreflang by creating head.phtml for each websites. Then to add, for example,

<link rel="alternate" href="http://www.mywebsite.com<?php $urlString = Mage::helper('core/url')->getCurrentUrl(); $url = Mage::getSingleton('core/url')->parseUrl($urlString); $path = $url->getPath();echo $path ?>" hreflang="en-gb" />

This works. And so far Google Webmastertool is not giving any errors. However, this method obviously doesn't list all the available languages in my shop. But if I don't create each head.phtml and just have one head.phtml with the code above, it will add extra store code when you are on different website. Any good solution for this?

Try replacing

$storeCode = substr(Mage::getStoreConfig('general/locale/code', $store->getId()),0,2);

with this:

$storeCode = strtolower(str_replace('_', '_', Mage::getStoreConfig('general/locale/code', $store->getId())));
