Amazon MWS GetLowestOfferListingsForASIN и SimpleXML не работают

Вот некоторые примеры данных, которые я пытаюсь использовать:

Вот мой код:

            $param = array();
$param['AWSAccessKeyId']    = 'ACCESS_KEY';
$param['Action']            = 'GetLowestOfferListingsForASIN';
$param['SellerId']          = 'SELLER_ID';
$param['SignatureMethod']   = 'HmacSHA256';
$param['SignatureVersion']  = '2';
$param['Timestamp']         = gmdate("Y-m-d\TH:i:s.\\0\\0\\0\\Z", time());
$param['Version']           = '2011-10-01';
$param['MarketplaceId']     = 'ATVPDKIKX0DER';
$param['ItemCondition']     = 'new';

//get all variations (limit 9)
$inc=1;
foreach($variations as $key=>$asin){
if($inc <= 9){$param['ASINList.ASIN.' . $inc] = $asin;}
$inc++;
}

$secret = 'SECRET';

$url = array();
foreach ($param as $key => $val) {
$key = str_replace("%7E", "~", rawurlencode($key));
$val = str_replace("%7E", "~", rawurlencode($val));
$url[] = "{$key}={$val}";
}

sort($url);

$arr   = implode('&', $url);

$sign  = 'GET' . "\n";
$sign .= 'mws.amazonservices.com' . "\n";
$sign .= '/Products/2011-10-01' . "\n";
$sign .= $arr;

$signature = hash_hmac("sha256", $sign, $secret, true);
$signature = urlencode(base64_encode($signature));

$link  = "https://mws.amazonservices.com/Products/2011-10-01?";
$link .= $arr . "&Signature=" . $signature;

$ch = curl_init($link);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

$response = preg_replace('/&(?!#?[a-z0-9]+;)/', '&amp;', $response);
$price_data = simplexml_load_string($response);

$node = $price_data->GetLowestOfferListingsForASINResult->Product;
foreach($node as $product){
$asin = $product->Identifiers->MarketplaceASIN->ASIN;

$node = $product->LowestOfferListings->LowestOfferListing->Price->LandedPrice;
foreach($node as $price){
$amzn_price = $price->Amount;
}

echo "$asin $amzn_price <br />";
}

Я успешно использую очень похожий код для ListMatchingProducts. Я пытаюсь перебрать результаты, чтобы сопоставить самые низкие цены с их ASIN, но это дает мне только первый результат вместо всех результатов. Я пытался использовать детей и большинство других вещей, о которых я могу думать, но все же безуспешно.

Решение

Посмотрите на мой код ниже, если это поможет:

$response = $service->getLowestOfferListingsForASIN($request);

$dom = new DOMDocument();
$dom->loadXML($response->toXML());
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$xml_data = $dom->saveXML();
$dom->loadXML($xml_data);

$otherOfferXml = simplexml_load_string($xml_data);

foreach($otherOfferXml as $offers)
{
// Skipping last RequestID section
if(!isset($offers["status"]))
continue;

// Checking if the API returned any error then continue to next SKU
if($offers["status"] != "Success")
continue;

$asin = (String) $offers->Product->Identifiers->MarketplaceASIN->ASIN;

// Going through all ASIN's offers to get price
$seller_counter = 0;
$others_response_data[$asin] = "";
foreach($offers->Product->LowestOfferListings->LowestOfferListing as $offers_list)
{
$others_response_data[$asin][$seller_counter]["LandedPrice"] = (String) $offers_list->Price->LandedPrice->Amount;
$others_response_data[$asin][$seller_counter]["ListingPrice"] = (String) $offers_list->Price->ListingPrice->Amount;
$others_response_data[$asin][$seller_counter]["Shipping"] = (String) $offers_list->Price->Shipping->Amount;
$others_response_data[$asin][$seller_counter]["Fulfillment"] = $fulfillment_channel;
$others_response_data[$asin][$seller_counter]["SKU"] = $asin_array[$asin]["sku"];
$others_response_data[$asin][$seller_counter]["AZN_ASIN"] = $asin;
$seller_counter++;
}
}
