#41955 [NEW]: addChild() with no namespace defined ignores the default namespace

From: hubert dot roksor at gmail dot com Operating system: PHP version: 5CVS-2007-07-10 (snap) PHP Bug Type: SimpleXML related Bug description: addChild() with no namespace defined ignores the default namespace Description: ------------ When adding a non-namespaced element to namespaced one, the new element is created under its parent's namespace instead of the scope's default namespace. In the reproduce code below we create a tree whose root element carries an empty default namespace declaration, with one "child" element under a custom namespace. We use addChild() to add a grandchild with no namespace defined. As per my understanding of XML Namespaces specifications, that element should be created under the default namespace and since the default namespace is empty the element should not use any namespace at all. A few notes: - moving the default namespace declaration to the child node does not change the outcome - using a non-empty default namespace does not change the outcome - specifying an empty namespace using addChild()'s third parameter gives the expected result Tested on: PHP 5.2.4-dev (cli) (built: Jul 10 2007 12:04:20) libXML Version => 2.6.26 SimpleXML Revision => $Revision: 1.151.2.22.2.33 $ Thanks for reading, and thanks for fixing my previous bugs so quickly ;) Reproduce code: --------------- <?php $xml = simplexml_load_string('<?xml version="1.0" encoding="utf-8"?> <root xmlns:myns="http://myns" xmlns=""> <myns:child /> </root>'); $children = $xml->children('http://myns'); $children[0]->addChild('grandchild', 'hello'); echo $xml->asXML(); ?> Expected result: ---------------- <?xml version="1.0" encoding="utf-8"?> <root xmlns:myns="http://myns" xmlns=""> <myns:child><grandchild>hello</grandchild></myns:child> </root> Actual result: -------------- <?xml version="1.0" encoding="utf-8"?> <root xmlns:myns="http://myns" xmlns=""> <myns:child><myns:grandchild>hello</myns:grandchild></myns:child> </root> -- Edit bug report at http://bugs.php.net/?id=41955&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41955&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41955&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41955&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41955&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41955&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41955&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41955&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41955&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41955&r=support Expected behavior: http://bugs.php.net/fix.php?id=41955&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41955&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41955&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41955&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41955&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41955&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41955&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41955&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41955&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41955&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41955&r=mysqlcfg
