ID: 55700 Comment by: thomas at weinert dot info Reported by: thomas at weinert dot info Summary: Disable automatic registration on a DOMXpath object. Status: Assigned Type: Feature/Change Request Package: DOM XML related PHP Version: 5.3.8 Assigned To: rrichards Block user comment: N Private report: N New Comment: This should not brake BC because the default value of the option would still be TRUE. If the developer does not set the option to FALSE it will still show the same unpredictable behavior like before. The idea is to make a transition from automatic to manual registration less painful and more secure. But I am not sure about the evaluate()/query() parameter. It would get at least more complex. (NULL = default, use option value) Previous Comments: ------------------------------------------------------------------------ [2011-09-15 12:24:48] paj...@php.net See https://bugs.php.net/bug.php?id=49490 as well ------------------------------------------------------------------------ [2011-09-15 12:19:52] paj...@php.net hi Rob! Can you take a look pls? Afaict it is not BC but this behavior never really works :) ------------------------------------------------------------------------ [2011-09-15 11:16:33] thomas at weinert dot info Description: ------------ DOMXpath currently registers namespaces of the current context or the document element automatically. This results in broken and inconsistent results (Bug #49490). An argument has been added to evaluate() and query() to change this behavior. The current situation is that the argument and the context argument has ALWAYS to be used to have predictable results. A better way would be an option on the DOMXpath object. An option would not only mean less code, it will also allow to just change one part (initialization of ones DOMXpath instance), without the need to modify all occurrences evaluate()/query() in existing source. Test script: --------------- <?php $dom = new DOMDocument(); $dom->loadXML( '<foobar><a:foo xmlns:a="urn:a">'. '<b:bar xmlns:b="urn:b"/></a:foo>'. '</foobar>' ); $xpath = new DOMXPath($dom); // disable automatic namespace registration $xpath->enableRegisterNodeNS = FALSE; $context = $dom->documentElement->firstChild; $xpath->registerNamespace('a', 'urn:b'); var_dump( $xpath->evaluate( 'descendant-or-self::a:*', $context )->item(0)->tagName ); ?> Expected result: ---------------- string(5) "b:bar" Actual result: -------------- string(5) "a:foo" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55700&edit=1
