ID: 37817 Updated by: [EMAIL PROTECTED] Reported By: ecervetti at ch-hyeres dot fr -Status: Assigned +Status: Bogus Bug Type: SimpleXML related Operating System: Linux mandriva 2006 PHP Version: 5.1.4 Assigned To: helly New Comment:
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 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.

It behaves in the same way in PHP 5.1.4 under Solaris 10 and Ubuntu 6.06. ------------------------------------------------------------------------ [2006-06-19 08:02:57] [EMAIL PROTECTED] Verified with 5.2 ------------------------------------------------------------------------ [2006-06-15 12:24:42] ecervetti at ch-hyeres dot fr 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" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37817&edit=1
