How to append XML string to DOMDocument without namespaces - php

Question

I'm using PHP and have to build a SOAP (1.1, Document/Literal) request that contains a XML message inside soap:Body tag.
My first issue is that I'd never used this "protocol" before.
My XML message is quite complex so I'm using SimpleXMLElement class to build it separately. To compose the SOAP message, I have two XML strings:
1- The SOAP structure.
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Header></soap:Header>
<soap:Body>...</soap:Body>
</soap:Envelope>
2- My Custom XML String
<eSocial xmlns="http://www.esocial.gov.br/schema/lote/eventos/envio/v2_2_02" grupo="1">
<envioLoteEventos>
<ideEmpregador tpInsc="1" nrInsc="0000000012"/>
<ideTransmissor tpInsc="1" nrInsc="0000000012"/>
<eventos>
<eSocial xmlns="http://www.esocial.gov.br/schema/evt/evtInfoEmpregador/v2_2_02">
<evtInfoEmpregador Id="8515">...</evtInfoEmpregador>
</eSocial>
</eventos>
</envioLoteEventos>
</eSocial>
What I need: The second string inside soap:Body tag exactly as it is.
What I get: The second string inside soap:Body with a bunch of namespaces automatically added by DOMDocument.
The algorithm (not full code) that I'm using:
$soapBodyElement = new SimpleXMLElement($soapBodyString);
$customMessageElement = new SimpleXMLElement($customMessageString);
// Some operations...
$domParent = dom_import_simplexml($soapBodyElement);
$domChild = dom_import_simplexml($customMessageElement);
$domDocument = $domParent->ownerDocument->importNode($domChild, true);
$domParent->appendChild($domDocument);
echo $domParent->ownerDocument->saveXML();
Output:
<soap:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Header/>
<soap:Body>
<eSocial xmlns="http://www.esocial.gov.br/schema/lote/eventos/envio/v2_2_02" xmlns:default="http://www.esocial.gov.br/schema/evt/evtInfoEmpregador/v2_2_02" xmlns:default1="http://www.w3.org/2000/09/xmldsig#" grupo="1">
<envioLoteEventos>
<ideEmpregador tpInsc="1" nrInsc="0000000012"/>
<ideTransmissor tpInsc="1" nrInsc="0000000012"/>
<eventos>
<default:eSocial xmlns="http://www.esocial.gov.br/schema/evt/evtInfoEmpregador/v2_2_02">
<default:evtInfoEmpregador Id="2550">...</default:evtInfoEmpregador>
</default:eSocial>
</eventos>
</envioLoteEventos>
</eSocial>
</soap:Body>
</soap:Envelope>
Honestly, I don't know why this default prefixes (namespaces?) were added.
How can I append two XML strings without this automatic behavior?

You could use the Marshal XML Serializer which is much easier to use then DOMDocument and SimpleXML.
Then you could do the following:
SoapEnvelopeMapper.php
use KingsonDe\Marshal\AbstractXmlMapper;
class SoapEnvelopeMapper extends AbstractXmlMapper {
/**
* #var AbstractXmlMapper
*/
private $messageMapper;
public function __construct(AbstractXmlMapper $messageMapper) {
$this->messageMapper = $messageMapper;
}
public function map($data) {
return [
'soap:Envelope' => [
$this->attributes() => [
'xmlns:xsi' => 'http://www.w3.org/2001/XMLSchema-instance',
'xmlns:xsd' => 'http://www.w3.org/2001/XMLSchema',
'xmlns:soap' => 'http://www.w3.org/2003/05/soap-envelope',
],
'soap:Header' => null,
'soap:Body' => $this->item($this->messageMapper, $data),
]
];
}
}
SoapMessageMapper.php
use KingsonDe\Marshal\AbstractXmlMapper;
class SoapMessageMapper extends AbstractXmlMapper {
public function map($data) {
return [
'eSocial' => [
$this->attributes() => [
'xmlns' => 'http://www.esocial.gov.br/schema/lote/eventos/envio/v2_2_02',
'xmlns:default' => 'http://www.esocial.gov.br/schema/evt/evtInfoEmpregador/v2_2_02',
'xmlns:default1' => 'http://www.w3.org/2000/09/xmldsig#',
'grupo' => 1,
],
'envioLoteEventos' => [
'ideEmpregador' => [
$this->attributes() => [
'tpInsc' => 1,
'nrInsc' => '0000000012',
],
],
'ideTransmissor' => [
$this->attributes() => [
'tpInsc' => 1,
'nrInsc' => '0000000012',
],
],
],
'eventos' => [
'eSocial' => [
$this->attributes() => [
'xmlns' => 'http://www.esocial.gov.br/schema/evt/evtInfoEmpregador/v2_2_02',
],
'evtInfoEmpregador' => [
$this->attributes() => [
'Id' => 2550,
],
$this->data() => '...',
],
],
],
]
];
}
}
SoapResponse.php
$data = new \stdClass();
$messageMapper = new SoapMessageMapper();
$envelopeMapper = new SoapEnvelopeMapper($messageMapper);
$xml = MarshalXml::serializeItem($envelopeMapper, $data);
