[PHP-DEV] SimpleXML returning attributes as objects instead of strings

[David Sklar]

SimpleXML returns attribute values as SimpleXMLElement objects instead 
of strings. E.g, given this:

$sxe = simplexml_load_string('<octopus arms="eight" legs="">Doc 
Ock</octopus>');

$sxe['arms'] and $sxe['legs'] are SimpleXMLElement objects.
This mostly works OK, but causes problems when using empty() to test if 
an attribute has a value. empty($sxe['arms']) is false, but so is 
empty($sxe['legs']).

An easy workaround is to use strlen() instead of empty(), I suppose 
(except if an attribute value is "0"), but I am wondering why SimpleXML 
works this way.

Thanks,
David
