How to reference an item in a PHP object named "@attributes"?

[yllus]

I've attached some code - I've been wondering this for a while. I did a print_r() on a PHP object called $xml. It has an element called @attributes. I just can't figure out how to access that element.

$xml->@attributes['VER'] doesn't work (throws error).
$xml->{@attributes}['VER'] comes back blank.
$xml->{'@attributes'}['VER'] shows the same as above.

I'm stumped. Any ideas?

SimpleXMLElement Object ( [@attributes] => Array ( [VER] => 3.2 ) )

maybe [man]get_class_vars[/man] ?

Or perhaps this:

$str = '@attributes';
print_r($xml->$str);

$xml->{'@attributes'}['VER'] should be correct. If you are getting a blank from printing it, then something else is wrong.
