Get body content from xml in php curl request - php

Question

I am using below code for SOAP request.
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://example.com?WSDL",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS =>"<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ns1=\"http://Xyz.Abc\" xmlns:ns2=\"http://tempuri.org/\"><SOAP-ENV:Body><ns2:GetStatus><ns1:ReferenceNo>12345</ns1:ReferenceNo></ns2:GetStatus></SOAP-ENV:Body></SOAP-ENV:Envelope>",
CURLOPT_HTTPHEADER => array(
"Content-Type: text/xml"
),
));
$response = curl_exec($curl);
curl_close($curl);
echo $response;
Response:
Getting below response when I set header('Content-type: application/xml'); in php script which is correct.
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing">
<env:Header>...</env:Header>
<env:Body>
<GetStatusResponse xmlns:s1="http://Xyz.Abc" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://tempuri.org/" xmlns="http://tempuri.org/">
<s1:StatusResponse>
<s1:Test ResponseCode="INPROGRESS" ResponseMessage="Reference no. 12345"/>
</s1:StatusResponse>
</GetStatusResponse>
</env:Body>
</env:Envelope>
How can I extract Body values from the response without just printing on browser?
Here is what I tried
Remove xml header and parse response string by simplexml_load_string method.
$xml = simplexml_load_string($response);
echo $xml;
$json = json_encode($response);
$arr = json_decode($json,true);
print_r($arr);
I also tried with SimpleXMLElement, but, it's printing empty response:
$test = new SimpleXMLElement($response);
echo $test;
But, it's printing empty result.

SimpleXML is an object. It isn't the full XML string as you might think. Try this.
//Cast to string to force simpleXml to convert into a string
$xmlString = $xml->asXML();
echo $xmlString . "\n";
I'm pretty sure you can't do this because $response is XML. Trying to json_encode it doesn't make sense.
$json = json_encode($response);
I did this:
<?php
$x = '<?xml version="1.0" ?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing">
<env:Header>...</env:Header>
<env:Body>
<GetStatusResponse xmlns:s1="http://Xyz.Abc" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://tempuri.org/" xmlns="http://tempuri.org/">
<s1:StatusResponse>
<s1:Test ResponseCode="INPROGRESS" ResponseMessage="Reference no. 12345"/>
</s1:StatusResponse>
</GetStatusResponse>
</env:Body>
</env:Envelope>';
$xml = simplexml_load_string($x);
echo $xml->asXml();
echo "\n";
And I get this output:
<?xml version="1.0"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing">
<env:Header>...</env:Header>
<env:Body>
<GetStatusResponse xmlns:s1="http://Xyz.Abc" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://tempuri.org/" xmlns="http://tempuri.org/">
<s1:StatusResponse>
<s1:Test ResponseCode="INPROGRESS" ResponseMessage="Reference no. 12345"/>
</s1:StatusResponse>
</GetStatusResponse>
</env:Body>
</env:Envelope>
This explains how to specify namespaces.
https://www.php.net/manual/en/simplexmlelement.attributes.php
$xml->registerXPathNamespace('e', 'http://schemas.xmlsoap.org/soap/envelope/');
$xml->registerXPathNamespace('s', 'http://Xyz.Abc');
$result = $xml->xpath('//s:Test');
$response = $result[0]->attributes();
echo "Response Code = " . $response['ResponseCode'] . "\n";
echo "Response Message = " . $response['ResponseMessage'] . "\n";
