Parse SOAP response with namespaces in PHP [duplicate]

Question

Any recommendations how to parse this SOAP response and obtain the value of name for the report_type? Notice there are two instances of name; one under report_type and the other under severity.

Here is the SOAP response

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Body> <ns1:getIRResponse xmlns:ns1="http://ws.icontent.idefense.com/V3/2"> <ns1:return xsi:type="ns1:IRResponse" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <ns1:report_type> <ns1:id>0</ns1:id> <ns1:name>Original Vulnerability</ns1:name> </ns1:report_type> <ns1:severity> <ns1:id>0</ns1:id> <ns1:name>HIGH</ns1:name> </ns1:severity> </ns:return> </ns1:getIRResponse> </soapenv:Body> </soapenv:Envelope>

Here is the PHP code I'm using:

<?php $xml = simplexml_load_string($response); $xml->registerXPathNamespace('ns1', 'http://ws.icontent.idefense.com/V3/2'); foreach ($xml->xpath('//ns1:report_type/name') as $item) { echo 'Name: '.$item,'<br>'; } ?>

The PHP code doesn't echo anything. When I use ($xml->xpath('//ns1:name') as $item) it returns both names (Original Vulnerability and HIGH).

I know I'm missing something stupid. Can you help please? Thank you in advance!

Can I ask why the need to parse XML in the first place? Are you not using the built in SOAP client and sourcing this data via some other means? — Scuzzy

Firstly, I've corrected this element

</ns:return>

and changed it to

</ns1:return>

I seem to get the result you're after by duplicating the namespace prefix in both xpath segments

$xml = simplexml_load_string($response); $xml->registerXPathNamespace('ns1','http://ws.icontent.idefense.com/V3/2'); foreach ($xml->xpath('//ns1:report_type/ns1:name') as $item) { echo 'Name: '.$item,'<br>'; }

output

Name: Original Vulnerability
