PHP Parsing SOAP response [duplicate]

Question

I'm trying to parse the following SOAP response, and need some guidance:

<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> <env:Header/> <env:Body> <ns2:LookupResponse xmlns:ns2="http://path-to/schemas"> <ns2:Name>My Name</ns2:Name> <ns2:Address1>test</ns2:Address1> <ns2:Address2>test</ns2:Address2> ... </ns2:LookupResponse> </env:Body> </env:Envelope>

I retreive the response via cURL:

$url = 'https://path-to-service'; $success = FALSE; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSLVERSION, 3); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $request); curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: text/xml; charset=utf-8', 'Content-Length: ' . strlen($request) )); $ch_result = curl_exec($ch); $ch_error = curl_error($ch); curl_close($ch);

I'm new to all of this, so forgive obvious errors, but I am then trying to iterate through the response as an object, as parsed by the simpleXML extension, referencing the SO answer here and using the simplexml_debug plugin to echo object content.

if(empty($ch_error)) { $xml = simplexml_load_string($ch_result, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); $xml ->registerXPathNamespace('env', 'http://schemas.xmlsoap.org/soap/envelope/'); $xml ->registerXPathNamespace('ns2', 'http://path-to/schemas'); echo '<pre>'; simplexml_dump($xml); echo '</pre>'; } else { echo 'error'; show($ch_error); exit; }

This gives me the following:

SimpleXML object (1 item) [ Element { Namespace: 'http://schemas.xmlsoap.org/soap/envelope/' Namespace Alias: 'env' Name: 'Envelope' String Content: '' Content in Namespace env Namespace URI: 'http://schemas.xmlsoap.org/soap/envelope/' Children: 2 - 1 'Body', 1 'Header' Attributes: 0 } ]

I want to get to the stage where I can iterate through the Body of the XML document, using either a foreach loop, or merely pointing directly to the relevant data ($title = (string)$data->title;). How can I proceed from my current position to get to that stage? I don't really know what comes next, and I just flat-out don't understand the documentation provided for the SOAP extension in PHP. I would rather use 'basic' code to achieve what I need.

This topic should help you solving your problem.

Adapted to your problem :

$xml = simplexml_load_string($ch_result, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); $ns = $xml->getNamespaces(true); $soap = $xml->children($ns['env']); $res = $soap->Body->children($ns['ns2']); foreach ($res->LookupResponse as $item) { echo $item->Name.PHP_EOL; }

Thanks for that reference. Trying this (with the same code):

$xml = simplexml_load_string($ch_result); $ns = $xml->getNamespaces(true); $envelope = $xml->children($ns['env']); $body = $envelope->body->children($ns['ns2']); echo $body->Name;

returns Warning: main(): Node no longer exists. Clearly I'm missing a step somewhere (although the logic is becoming clear to me)...

$body contains the parent of LookupResponse so you have to loop over them to get all the considered names ! You can do it like that : foreach ($body->LookupResponse as $item) { echo $item->Name.PHP_EOL; }. Also be very careful about the case of your elements : body <> Body ! So you have to write : $body = $envelope->Body->children($ns['ns2']);.
