BP_Core_oEmbed_Extension::oembed_xml_request( bool $served, WP_HTTP_ResponseInterface $result, WP_REST_Request $request, WP_REST_Server $server )

If oEmbed request wants XML, return XML instead of JSON.

$result

(Required) Result to send to the client. Usually a WP_REST_Response.

$request

(Required) Request used to generate the response.
