I've encountered what seems to me to be something of an oddity while

around with XML parsing in PHP, and I wondered if any of you might be able
to clear up my confusion...

Here's a little code:

$xmlDoc = new DOMDocument();
$xmlDoc->load('widget_data.xml');
$widgets = $xmlDoc->getElementsByTagName('widget');

My understanding was that '$widgets' is an array of elements,

Nope - it's a DOMNodeList object, that has support for PHP5 iterators, so
you
can use it in a foreach loop.

Thanks. That's my missing piece. I have quite a bit of experience of PHP
prior to 5, but I'm just feeling my way with some of the 5 stuff. :-)
