Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
[url]http://www.php.net/manual/[/url] and the instructions on how to report
a bug at [url]http://bugs.php.net/how-to-report.php[/url]

When you access an non-existenet element SimpleXML creates a
node in the DOM tree. This node is then present for future
iterations of the DOM tree.

To avoid creating the DOM node, use the isset($xml->typebal3)
code to check for its presence. This will allow you to
determine if the node exists and not create if it does not.

I've found a post in the mailing list about this issue:
[url]http://www.mail-archive.com/php-general@lists.php.net/msg190494.html[/url]
It says that "it's not a bug, it's a feature".

It behaves in the same way in PHP 5.1.4 under Solaris 10 and Ubuntu
6.06.

Description:
------------
I try to access a particular element of xml data with the
foreach($xml->name_of_element ....) syntax.

But I don't know if this element exists.

When the element don't exists, no problem the first time;
It don't goes inside the loop.

But If I call the same loop a second time, it goes inside the loop, as
if the element exists.


Reproduce code:
---------------
$string =
"<data><typebal1>pim</typebal1><typebal2>poom</typebal2></data>";


$xml = simplexml_load_string($string);

foreach($xml->typebal3 as $bal) {
print "<br />I should not be here<br />";
}

foreach($xml->typebal3 as $bal) {
print "<br />I should either not be here<br />";
}

//this script renders "I should either not be here"

Expected result:
----------------
this script should not print anything

Actual result:
--------------
this script renders "I should either not be here"
