Description:
------------
I  upgraded my PHP version from 5.1.* to 5.2.0
XML string loaded into two different simpleXML objects.
The result of comparing xml node attributes (without any specific cast) in version 5.2.0 is different then used to be in 5.0.3 and 5.1.5.
I also checked the last snapshot for windows marked as "PHP Version 5.2.1RC2-dev" and got the same output as 5.2.0

Reproduce code:
---------------
<?php


$xmlStr = "<test id=\"5\"><name>hello</name></test>";

$xml_1 = simplexml_load_string($xmlStr);

$xml_2 = simplexml_load_string($xmlStr);

var_dump($xml_1);
var_dump($xml_2);

print("<br/>");

if($xml_1['id'] == $xml_2['id']) {
    print("equal ids");
}
else
{
    print("not equal ids");
}

print("<br/>");
if($xml_1->name == $xml_2->name)
{
    print("equal names");
}
else
{
    print("not equal names");
}

?>


Expected result:
----------------
equal ids
equal names

Actual result:
--------------
not equal ids
not equal names
