    $dom = new DomDocument('1.0','iso-8859-15');

    $ht_ml = $dom->appendChild($dom->createElement('html'));

    $he_ad = $ht_ml->appendChild($dom->createElement('head'));

    $tit_le= $he_ad->appendChild($dom->createElement('title'));
    $tit_le->appendChild($dom->createTextNode('DOMAttr test'));

    $me_ta = $he_ad->appendChild(new DOMElement('meta'));
    $me_ta->setAttributeNode(new DOMAttr('name', 'Description'));
    $me_ta->setAttributeNode(new DOMAttr('content', 'example'));

    $me_ta = $he_ad->appendChild(new DOMElement('meta'));
    $me_ta->setAttributeNode(new DOMAttr('name', 'Author'));
    $me_ta->setAttributeNode(new DOMAttr('content', 'karvjorm'));
