Get attribute text from get_available_variations

Hi,

I have created a XML feed plugin, which is working fine.

One issue I have noticied, that when accessing the attributes for a variable product not the text form is presented in the array but the slug.
So ?okoláda => cokolada, banán => banan. I need the version (?okoláda, banán).

Is there a way to get the text form? Or I have to create a replace array. I dont want to do that because we have 250 attributes, but if it is needed… :).

Part of my code:

$variations = $product->get_available_variations();

foreach ($variations as $var_id){
$productname = $dom->createElement("PRODUCTNAME");
$producta->appendChild($productname);

if (!empty($var_id['attributes']['attribute_pa_prichut'])){
$cdata = $dom->createCDATASection($loop->post->post_title.' '.$var_id['attributes']['attribute_pa_prichut']);
} elseif (!empty($var_id['attributes']['attribute_pa_velkost'])) {
$cdata = $dom->createCDATASection($loop->post->post_title.' '.strtoupper($var_id['attributes']['attribute_pa_velkost']));
} elseif (!empty($var_id['attributes']['attribute_pa_farba'])) {
$cdata = $dom->createCDATASection($loop->post->post_title.' '.$var_id['attributes']['attribute_pa_farba']);
} else {
$cdata = $dom->createCDATASection($loop->post->post_title);
}
}
