PHP SimpleXML is both an Object and an Array? Inconceivable!

Question

Ok, check out this voodoo:

This code:

$xml = new SimpleXMLElement($xml);
 $var = $xml->QBXMLMsgsRs->ClassQueryRs;
 $vars = print_r($var,true);

Returns:

    SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [requestID] => Q2xhc3NRdWVyeXw1
            [statusCode] => 0
            [statusSeverity] => Info
            [statusMessage] => Status OK
        )

    [ClassRet] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [ListID] => 80000002-1241128424
                    [TimeCreated] => 2009-04-30T17:53:44-05:00
                    [TimeModified] => 2009-04-30T17:53:44-05:00
                    [EditSequence] => 1241128424
                    [Name] => D1
                    [FullName] => D1
                    [IsActive] => true
                    [Sublevel] => 0
                )

            [1] => SimpleXMLElement Object
                (
                    [ListID] => 80000001-1241128320
                    [TimeCreated] => 2009-04-30T17:52:00-05:00
                    [TimeModified] => 2009-04-30T17:52:00-05:00
                    [EditSequence] => 1241128320
                    [Name] => K1
                    [FullName] => K1
                    [IsActive] => true
                    [Sublevel] => 0
                )

            [2] => SimpleXMLElement Object
                (
                    [ListID] => 80000003-1241128452
                    [TimeCreated] => 2009-04-30T17:54:12-05:00
                    [TimeModified] => 2009-04-30T17:54:12-05:00
                    [EditSequence] => 1241128452
                    [Name] => S1
                    [FullName] => S1
                    [IsActive] => true
                    [Sublevel] => 0
                )
        )

)

However, this code:

$xml = new SimpleXMLElement($xml);
 $var = $xml->QBXMLMsgsRs->ClassQueryRs->ClassRet;
 $vars = print_r($var,true);

Returns:

SimpleXMLElement Object
(
    [ListID] => 80000002-1241128424
    [TimeCreated] => 2009-04-30T17:53:44-05:00
    [TimeModified] => 2009-04-30T17:53:44-05:00
    [EditSequence] => 1241128424
    [Name] => D1
    [FullName] => D1
    [IsActive] => true
    [Sublevel] => 0
)

For the life of me, I cannot access the rest of this object! Echo, print_r.... if I try to access the specific variable, it disappears!

PHP's SimpleXml is an object that implements the ArrayAccess interface which means that you can reference elements with the array style syntax.

When I try to access it as an array, I get nothing. When I access it as an object, I only get the first result.

Can you post your xml too so we can test and reproduce the issue?
