Get a list of available pages from pages.array

Since the language is tied to the suffix of the slug (e.g. index_de), you can perhaps try parsing that:

PHP Code:

// Initialize some variables to be used in the loop
$langSuffix  = '_de'; // your language

// Main loop
foreach ($pages as $page) {
  // check that the language suffix in the slug
  if (strpos($page['slug'], $langSuffix) !== -1) {
    // Do something with this language-specific page
    // ...
  }
  // ...
}
