$request->isXml();

Should validate the content type to be XML as well as check the validity of the content to be valid XML

$request->sentXml();

Should only validate the content type

Users usually forget the accept header but, if a user sends content-type XML, they expect XML in return unless they explicitly state otherwise.

Determine if a user wants XML by checking both the request Accept and Content Type headers...

Request::macro('wantsXml', function (bool $checkContentType = false) {
    $acceptableTypes = $this->getAcceptableContentTypes();

    $accepts = array_pop($acceptableTypes) ?? '';

    $acceptsXml = Str::contains($accepts, ['/xml', '+xml']);

    if ($acceptsXml) {
        return true;
    }

    if (! $checkContentType) {
        return false;
    }

    return $this->getContentType() == 'xml';
});

// ...

$request->wantsXml(true);
