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!

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
