Previous Comments: ------------------------------------------------------------------------ [2013-08-02 07:12:48] goetas at lignano dot it Description: ------------ registerNodeNS option (default to true) added with php 5.3.3 produces unexpected behavior and BC issue. $registerNodeNS = true seems to remove (overwrite) registered namespaces with DOMXPath::registerNamespace() method, Similar problem has been reported with #55700 Test script: --------------- <?php $dom = new DOMDocument('1.0', 'UTF-8'); $dom->loadXML(' <ns1:tag xmlns:ns1="http://my.com/ns1" xmlns:ns2="http://my.com/ns2"> <ns1:tag-2/> <ns2:extra/> </ns1:tag>'); $xpath = new DOMXPath($dom); $xpath->registerNamespace("ns2", "http://my.com/ns1"); echo $xpath->query("//ns2:tag-2", null, false)->length."\n"; echo $xpath->query("//ns2:tag-2", null, true)->length,"\n"; /* * registerNodeNS option should skip prefix registration if * same prefix is already registered with registerNamespace() method. */ Expected result: ---------------- 1 1 Actual result: -------------- 1 0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65375&edit=1
