загрузить файл XML через API

Я пытаюсь создать php-скрипт для отправки xml-файла через API в режиме онлайн.

Мой файл находится в /tmp/xxx.xml

PHP-код (связь по точным онлайн-API):

    <?phprequire_once 'ExactApi.php';

// Configuration, change these:
$clientId       = '{x}';
$clientSecret   = 'x';
$redirectUri    = "x";
$division       = "x";

try {

// Initialize ExactAPI
$exactApi = new ExactApi('fr', $clientId, $clientSecret, $division);

$exactApi->getOAuthClient()->setRedirectUri($redirectUri);

if (!isset($_GET['code'])) {

// Redirect to Auth-endpoint
$authUrl = $exactApi->getOAuthClient()->getAuthenticationUrl();
header('Location: ' . $authUrl, TRUE, 302);
die('Redirect');

} else {

// Receive data from Token-endpoint
$tokenResult = $exactApi->getOAuthClient()->getAccessToken($_GET['code']);
$exactApi->setRefreshToken($tokenResult['refresh_token']);

// List accounts
$response = $exactApi->sendRequest('crm/Accounts', 'get');
var_dump($response);

// Create account
$response = $exactApi->sendRequest('crm/Accounts', 'post', array(
'Status'            =>  'C',
'IsSupplier'        =>  True,
'Name'              =>  'xx',

Я хотел бы отправить файл XML (xxx.xml)

<?xml version="1.0" encoding="utf-8"?>
<eExact xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="eExact-XML.xsd">
<Items><Item code="2M31E93_IM"><IsSalesItem>1</IsSalesItem><Sales><Price><Currency code="EUR" /><Value>80.00</Value><VAT code="VN"></VAT></Price><Unit code="pc"><Description>Piece</Description></Unit></Sales><Costs><Price><Currency code="EUR" /><Value>591.53</Value></Price></Costs><ItemAccounts><ItemAccount><Account code="0000002"></Account><IsPrimary>1</IsPrimary><SupplierItemCode>2M31E93_IM</SupplierItemCode><Purchase><Price><Currency code="EUR" /><Value>50.00</Value><VAT code="AN"></VAT></Price><Unit code="pc"><Description>Piece</Description></Unit></Purchase><CanDropShip>1</CanDropShip></ItemAccount></ItemAccounts></Item></Items>
</eExact>

Что я должен добавить в свой php-файл, чтобы отправить мой xml-файл?

Спасибо всем
