Assistance required with PHP and XML soap response - php

Question

I'm junior to PHP and XML and require your assistance please.
How would I display only the values of the nodes in the xml response.
Example of what I would like to see:
name - Africa Direct
parent - 41711
invoiced - 1470002400
My code,
$wdsl = '*******';
$params = array(
'username'=>'********',
'password'=>'*******',
'parent'=>0
);
$options = array(
'trace'=>1
);
$client = new SoapClient($wdsl, $options);
$data = $client->__soapCall('get_customers', $params);
$response = $client->__getLastResponse();
var_export($response);
the results looks as follows:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Body>
<get_customersResponse xmlns="*********/API">
<s-gensym3>
<name xsi:type="xsd:string">Africa Direct</name>
<parent xsi:type="xsd:string">41711</parent>
<invoiced xsi:type="xsd:string">1470002400</invoiced>
<auto_topup xsi:type="xsd:float">0.000000</auto_topup>
<contact xsi:type="xsd:string">0</contact>
<invoices_due xsi:type="xsd:string">-2</invoices_due>
</s-gensym3>
</get_customersResponse>
</soap:Body>
</soap:Envelope>'
