Bug #54905 [Opn->Fbk]: inconsistant namespace behaviour with DocumentFragment

Edit report at https://bugs.php.net/bug.php?id=54905&edit=1 ID: 54905 Updated by: mike@php.net Reported by: andrew at miniatureworldmaker dot com dot au Summary: inconsistant namespace behaviour with DocumentFragment -Status: Open +Status: Feedback Type: Bug Package: DOM XML related Operating System: Fedora / Debian PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. This test case is quite convoluted, I think I get the opposite result, but I can't really tell. Please re-open this bug with a proper reproduce script.

When a DocumentFragment is created and the root element contains an xmlns attribute this is the behaviour currently displayed by PHP. However if a documentfragment is appended to an element already present in the DOM which contains an xmlns, the appended fragment appears to be assigned a default 'null' namespace. Test script: --------------- Scenario 1: xmlns is present in the fragment. <?php const BLAH_NS = 'http://blah.com/blah'; $xml = ' <root> <foo> <bar /> </foo> </root> '; $fragXML = '<content xmlns="'.BLAH_NS.'"><sneh>some</sneh><grah>here</grah><ul><li>one</li><li>two</li><li>three</li></ul></content>'; $doc = new DOMDocument('1.0','UTF-8'); $doc->formatOutput = true; $doc->preserveWhiteSpace = false; $doc->loadXML( $xml ); $xpath = new DOMXPath( $doc ); $barElement = $xpath->query( '//bar' )->item(0); // create a new element with xmlns="http://blah.com/blah" . The expectation is that // every child of this node will be part of this namespace as per the section on default // name spaces http://www.w3schools.com/XML/xml_namespaces.asp // create a new document Fragment $DOMFragment = $doc->createDocumentFragment(); $DOMFragment->appendXML( $fragXML ); // Attach the fragment to the rest of the document $barElement->appendChild( $DOMFragment ); // all good so far echo $doc->saveXML(); // register the bar name space so we can perform a lookup $xpath->registerNamespace('b', BLAH_NS); echo "\n\n\n"; // this doesn't work $grahElement = $xpath->query( '//b:grah' )->item(0); echo "Find //b:grah " .$grahElement->nodeValue."\n"; // this works $grahElement = $xpath->query( '//grah' )->item(0); echo "Find //grah ".$grahElement->nodeValue."\n"; ?> Scenario 2: The xmlns attribute is present on the element the fragment is attached to <?php const BLAH_NS = 'http://blah.com/blah'; $xml = ' <root> <foo> <bar /> </foo> </root> '; $fragXML = '<sneh>some</sneh><grah>here</grah><ul><li>one</li><li>two</li><li>three</li></ul>'; $doc = new DOMDocument('1.0','UTF-8'); $doc->formatOutput = true; $doc->preserveWhiteSpace = false; $doc->loadXML( $xml ); $xpath = new DOMXPath( $doc ); $barElement = $xpath->query( '//bar' )->item(0); // create a new element with xmlns="http://blah.com/blah" . The expectation is that // every child of this node will be part of this namespace as per the section on default // name spaces http://www.w3schools.com/XML/xml_namespaces.asp $contentElement = $doc->createElementNS( BLAH_NS, 'content' ); $barElement->appendChild( $contentElement ); // create a new document Fragment $DOMFragment = $doc->createDocumentFragment(); $DOMFragment->appendXML( $fragXML ); // Attach the fragment to the rest of the document $contentElement->appendChild( $DOMFragment ); // all good so far echo $doc->saveXML(); // register the bar name space so we can perform a lookup $xpath->registerNamespace('b', BLAH_NS); echo "\n\n\n"; // this doesn't work $grahElement = $xpath->query( '//b:grah' )->item(0); echo "Find //b:grah " .$grahElement->nodeValue."\n"; // this works $grahElement = $xpath->query( '//grah' )->item(0); echo "Find //grah ".$grahElement->nodeValue."\n"; ?> Expected result: ---------------- In both cases I would expect the output of: Find //b:grah here Find //grah Actual result: -------------- Find //b:grah Find //grah grahtest ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54905&edit=1
