Multidomain XML sitemap with Polylang and SEOPress

Polylang (multilingual plugin) allows you to have a different domain name by language.

If you use this option, you might also like to have an XML sitemap by language / domain.

To do this, you must have version 3.7.3 of SEOPress at least.

Copy and paste the code below into your functions.php file of your theme (child theme preferred) or into a must-use plugin.

Required version: 3.7.3
