php - How parsing out XML file with namespaces? -

i know similar questions posted before, can't parse out xml file namespaces.

here link because it's big post here: https://tsdrapi.uspto.gov/ts/cd/casestatus/sn86553893/info.xml

i tried using simplexml_load_file not create xml object. found similar problems , try this, provided downloaded file named 86553893.xml

here php code:

$xml= new simplexmlelement("86553893.xml");                             foreach($xml->xpath('//com:applicationnumber') $event) {                                 var_export($event->xpath('com:applicationnumbertext'));                         } 

you have register namespaces on each element want use them:

$xml= new simplexmlelement("86553893.xml"); $xml->registerxpathnamespace('com', 'http://www.wipo.int/standards/xmlschema/common/1'); foreach ($xml->xpath('//com:applicationnumber') $event) {   $event->registerxpathnamespace(     'com', 'http://www.wipo.int/standards/xmlschema/common/1'   );                            var_export($event->xpath('com:applicationnumbertext')); } 

this different in dom, use domxpath instance, single object , have register namespaces once.

$dom = new domdocument(); $dom->load("86553893.xml"); $xpath = new domxpath($dom); $xpath->registernamespace('com', 'http://www.wipo.int/standards/xmlschema/common/1');  foreach ($xpath->evaluate('//com:applicationnumber') $event) {   var_export($xpath->evaluate('string(com:applicationnumbertext)', $event)); }
