Hi i have a problems with simplexml_load_file, i'm not pretty sure how to do to order my array by a $item->padre.

I need to do foreach and order by $item->padre.=, i don't know how to do this.

function create_sitemap($sitemap){

$xml = file_exists('sitemap.xml') ? $xml = simplexml_load_file('sitemap.xml'): exit('Failed to open sitemal.xml.');

$xml = uasort($xml, function($a,$b){ return strcmp($a->padre, $b->padre); });

foreach ($xml->url as $item) {

echo "

" . $item->loc. "

" . $item->padre . "

}

}

Thanks in advance.
