以下是我尝试使用的一些示例数据：

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

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

我成功地为ListMatchingProducts使用了一个非常相似的代码。我试图循环结果以匹配最低价格到他们的ASIN，但这只给我第一个结果而不是所有结果。我尝试过使用儿童和我能想到的其他大部分事情，但仍然没有运气。

如果有帮助，请查看下面的代码：

$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"];
