Get price order using webservice

[java2dev]

Hello, I can save order from marketplace using this function

public function saveOrder($cart, $order_id)
    {
		
        $order = new Order();
        $customer = new Customer($this->linio_user_id);
        $context = Context::getContext();
        $order->product_list = $cart->getProducts();
        $order->id_address_delivery = $this->address_id;
        $order->id_address_invoice = $this->address_id;
        $order->id_cart = $cart->id;
        $order->id_currency = $cart->id_currency;
        $order->id_customer = $cart->id_customer;
        $order->id_carrier = $cart->id_carrier;
        $order->payment = 'Pay ';
        $order->module = 'L-sync';
        $order->conversion_rate = 1;
        $order->secure_key = $customer->secure_key;
        $order->current_state = _PS_OS_PREPARATION_;

        $order->reference = $order_id;
        $order->id_lang = $context->language->id;
        $order->id_shop = (int) $context->shop->id;
        $order->id_shop_group = (int) $context->shop->id_shop_group;

        $order->total_products = $order->total_products_wt = (float) $cart->getOrderTotal(
            false,
            Cart::ONLY_PRODUCTS,
            $order->product_list,
            $order->id_carrier
        );
        $order->total_paid_real = 0;
	
        $order->total_paid_tax_excl = $order->total_paid_tax_incl = (float) Tools::ps_round(
            (float) $cart->getOrderTotal(
                false,
                Cart::BOTH,
                $order->product_list,
                $order->id_carrier
            ),
            2
        );
        $order->total_paid = $order->total_paid_tax_incl;

        $order->invoice_date = '0000-00-00 00:00:00';
        $order->delivery_date = '0000-00-00 00:00:00';

        if ($order->add()) {
            $order_detail = new OrderDetail();
            $order_detail->createList($order, $cart, $order->current_state, $order->product_list);
            $data = array(
              'id_order' => $order->id,
              'id_linio_order' => $this->id,
            );
            Db::getInstance()->insert('liniosync_orders', $data);
            return true;
        }
        return false;
    }

I saved important order attribute but it miss price , I've tried using this but it doesn't work

 

$order->total_paid_tax_incl = (int) $xml->Body->Orders->Order->OrderId->Price;

 

any idea how I could save the price value in total_paid_tax_incl, always the value saved is 0.
