Bug #46672 [Asn->Wfx]: Cloned SimpleXML Output Different

Edit report at http://bugs.php.net/bug.php?id=46672&edit=1 ID: 46672 Updated by: rrichards@php.net Reported by: rfludwick at gmail dot com Summary: Cloned SimpleXML Output Different -Status: Assigned +Status: Wont fix Type: Bug Package: SimpleXML related Operating System: * PHP Version: 5.*, 6CVS (2009-04-01) Assigned To: rrichards New Comment: The asXML() method is special in regards to the document element as it treats it as a document node for simple trees. A clone of a document element is a regular element (a document can only have 1) and does not get special treatment. Patch breaks in memory tree. Either manually add the XML declaration to the clone or import to dom and clone the document and work off the new document.

Attached patch should fix that. ------------------------------------------------------------------------ [2008-12-30 14:49:29] rfludwick at gmail dot com I got the same result when using the snapshot, as well as version 5.2.8. ------------------------------------------------------------------------ [2008-11-25 23:35:36] rfludwick at gmail dot com Description: ------------ It appears that cloning a SimpleXML object will not produce the same XML output on asXML() as the original object. The original will output the XML header and a line break after the XML while the cloned object is missing these. Reproduce code: --------------- <?php $simplexml = new SimpleXMLElement("<root />"); $simplexml->path->to->node = "Zend"; $simplexml_2 = clone $simplexml; echo "|{$simplexml->asXML()}|\n|{$simplexml_2->asXML()}|"; Expected result: ---------------- |<?xml version="1.0"?> <root><path><to><node>Zend</node></to></path></root> | |<?xml version="1.0"?> <root><path><to><node>Zend</node></to></path></root> | Actual result: -------------- |<?xml version="1.0"?> <root><path><to><node>Zend</node></to></path></root> | |<root><path><to><node>Zend</node></to></path></root>| ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=46672&edit=1
