@karvjorm, Using this method is not exactly a good practice. Infact, I think it may be a bug. Names beginning with "xml" are reserved (for namespaces in this case). setAttribute() should return false in this case I think, but I suppose it doesn't. Still, the right way to do it is with createElementNS(). It lets you specify the namespace when creating the element node. So the equivalent to yours ($html added to allow word wrapping) is: $dom = new DomDocument('1.0','iso-8859-15'); $html = $dom->createElementNS('http://www.w3.org/1999/xhtml', 'html'); $ht_ml = $dom->appendChild($html); $ht_ml->setAttribute('xml:lang','fi'); $ht_ml->setAttribute('lang','fi');

$dom = new DomDocument('1.0','iso-8859-15'); $ht_ml = $dom->appendChild($dom->createElement('html')); $ht_ml->setAttribute('xmlns','http://www.w3.org/1999/xhtml'); $ht_ml->setAttribute('xml:lang','fi'); $ht_ml->setAttribute('lang','fi'); Result: <?xml version="1.0" encoding="iso-8859-15"?> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fi" lang="fi">
