XML parsing in PHP DOM via cURL - cannot get nodeValue if it is an address or URL date

I have this weird problem parsing an XML document in PHP loaded via cURL. I cannot get the nodeValue containing the url (I am trying to embed a simple RSS reader in my CMS). The strange thing is that it works for each node, except that it contains URL addresses and date (s).

Here is the code (I know this is a stupid solution, but I'm new to working with the DOM and parsing XML documents).

function file_get_contents_curl($url) {

$ch = curl_init();    // initialize curl handle
curl_setopt($ch, CURLOPT_URL, $url); // set url to post to
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // return into a variable
curl_setopt($ch, CURLOPT_TIMEOUT, 4); // times out after 4s
$result = curl_exec($ch); // run the whole process

return $result;
}

function vypis($adresa) {

$html = file_get_contents_curl($adresa);

$doc = new DOMDocument();
@$doc->loadHTML($html);

$nodes = $doc->getElementsByTagName('title');
$desc = $doc->getElementsByTagName('description');
$ctg = $doc->getElementsByTagName('category');
$pd = $doc->getElementsByTagName('pubDate');
$ab = $doc->getElementsByTagName('link');
$aut = $doc->getElementsByTagName('author');


for ($i = 1; $i < $desc->length; $i++) {

    $dsc = $desc->item($i);
    $titles = $nodes->item($i);
    $categorys = $ctg->item($i);
    $pubDates = $pd->item($i);
    $links = $ab->item($i);
    $autors = $aut->item($i);

    $description = $dsc->nodeValue;
    $title = $titles->nodeValue;
    $category = $categorys->nodeValue;
    $pubDate = $pubDates->nodeValue;
    $link = $links->nodeValue;
    $autor = $autors->nodeValue;

    echo 'Title:' . $title . '<br/>';
    echo 'Description:' . $description . '<br/>';
    echo 'Category:' . $category . '<br/>';
    echo 'Datum ' . gmdate("D, d M Y H:i:s",
       strtotime($pubDate)) . " GMT" . '<br/>';
    echo "Autor: $autor" . '<br/>';
    echo 'Link: ' . $link . '<br/><br/>';
}
}

Could you help me with this?
