Raw XML

matchXmlBody() accepts XML text, a resource, a PSR-7 stream, or a DOMDocument :

$pock->matchMethod(RequestMethod::POST)
    ->matchUri('https://api.example.com/users')
    ->matchXmlBody('<user><name>Jane</name><active>true</active></user>')
    ->reply(201)
    ->withHeader('Content-Type', 'application/xml')
    ->withXml('<user><id>42</id><name>Jane</name></user>');

When the DOM and XSL extensions are available, pock parses the XML and sorts nodes and attributes before comparison. Formatting and node order therefore do not cause a mismatch. Without that support, pock falls back to exact text comparison, so whitespace and ordering matter.

Malformed or empty parsed XML throws Pock\Exception\XmlException .

DTO serialization

matchSerializedXmlBody() serializes arrays or objects before passing the result to the XML matcher. withXml() uses the same serializer discovery for responses:

$pock->matchSerializedXmlBody(new CreateUser('Jane'))
    ->reply(201)
    ->withXml(new User(42, 'Jane'));

JMS Serializer is preferred when both supported serializers are installed. Symfony Serializer requires its XML encoder and object normalizer. To select configured instances explicitly:

use Pock\Factory\XmlSerializerFactory;
use Pock\Serializer\SymfonySerializerAdapter;
use Symfony\Component\Serializer\Encoder\XmlEncoder;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Serializer;

$serializer = new Serializer([new ObjectNormalizer()], [new XmlEncoder()]);
XmlSerializerFactory::setSerializer(new SymfonySerializerAdapter($serializer, 'xml'));

If no XML serializer can be discovered, serializer-aware object and array calls throw XmlException . Raw strings do not require a serializer.
