    getElementsByTagName returns a DOMNodeList. You can access each element by it’s numerical index (0 to length-1) as you already do, but just start at the end, not the beginning in your for loop, then count downwards:

    $x = $xmldoc->getElementsByTagName('note');
$nofnews = $x->length;
for ($i = $nofnews-1; $i > -1; $i--)
{
    $item = $x->item($i);
    $item_title = $item->getElementsByTagName('to')
                        ->item(0)->nodeValue;
    $item_link = $item->getElementsByTagName('from')
                        ->item(0)->nodeValue;
}

    This should already to it for you.
