Both ways are perfectly valid. $node and $newnode refer to the same
object. It was written the 1st way to demonstrate the return value of
appendChild(), because in many cases people create the element differently.
i.e.
$newnode = $doc->appendChild($doc->createElement("root"));
or
$newnode = $doc->appendChild(new DOMElement("root"));
Thank you very much for confirming that! I was not sure if it's really
the same.
Also, in the event $node is created using the new DOMElement syntax:
$node = new DOMElement("root");
the node is read only and must be appended into the tree before it can
be modified, so the example just tries to be neutral here regarding the
syntax used.
$node = new DOMElement("root");
is read only, while
$node = $doc->createElement("root");
is not? Why?
btw., I think this: http://news.php.net/php.internals/22117 is a very,
very, very good idea! I hope the patch will make it into core soon!
best regards
Andreas
