New Comment:
Thanks for your reply, but if that's the intended behavior (that
echo'ing the attribute prints it out as a string, but trying to compare
it doesn't work without a cast to a string), then the documentation
then needs to be updated. The 'Using attributes' example on
http://docs.php.net/en/ref.simplexml.html
says that what I'm trying to
do should work. That example then is invalid too.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
As Derick said, the explicit conversion is necessary because php tries
to convert the second argument to the first argument\'s type which is
an object. Generally it could work when you switch the order of
arguments but the explicit conversion makes it visible what you do.

If you cast to a string, it works:
if ((string) $sxe['a'] == '123')
I do think that should be necessary though.

Yes, doing 'var_dump($sxe['a']);' gives:
object(simplexml_element)#2 (1) {
[0]=>
string(3) "123"
}
But then changing my if line to:
if ($sxe['a'][0] == '123')
doesn't work either.
How does one then compare an attribute to another value? The
documentation at http://docs.php.net/en/ref.simplexml.html
states that
my original if statement should work (the example under 'Using
attributes'). That example doesn't work locally either because of the
same issue on the switch statement used.

Try doing a 'var_dump($sxe['a']);'...comparing string to an object
can't really be true in any case?

Description:
------------
Doing the following SimpleXML text comparison does not give the
expected results.
Reproduce code:
---------------
<?php
$sxe = simplexml_load_string('<root a="123" />');
echo $sxe['a']."\n";
if ($sxe['a'] == '123')
{
echo 'They are equal.'."\n";
}
else
{
echo 'They are not equal.'."\n";
}
?>
Expected result:
----------------
123
They are equal.
Actual result:
--------------
123
They are not equal.
