如何获取销售排名，金额，产品变暗，ID和ASIN？我一直在寻找一段时间，并且没有找到关于结肠的任何信息。

我尝试使用的代码是：

for($i = 0; $i < (count($groupedArrays) - 0); $i++){
    $xmlFilePath = 'xml/' . $file_name . $i . '.xml';
    $xml = simplexml_load_file($xmlFilePath);

foreach($xml->children() as $items) { 
    if ($items->GetMatchingProductForIdResult->Error) {
        continue;
    }
    $upcTag = $items['Id'] . ',';
    if($items->GetMatchingProductForIdResult->Products->Product->AttributeSets->Relationship == FALSE){
        echo $items->GetMatchingProductForIdResult->Products->Product->AttributeSets->SalesRankings->SalesRank[0] . ',';
    } else {
        echo  $items->GetMatchingProductForIdResult->Products->Product->AttributeSets->Relationship->VariationParent->Identifiers->MarketplaceASIN->ASIN . ',';
    }
        $subject = "<ns2:Amount></ns2:Amount>";
        preg_match_all('/<[^:]*:([^>]*)>(.*)<\/[^>]*>/', $subject, $matches);

$i = 1;
$ii = 0;
foreach ($matches as $key => $value) {          
   $newArr[$matches[$i][$ii]] = $matches[$ii][$ii];            
   $ii++;
   $i++;
}

$result = array_filter($newArr); 
foreach($result as $key => $value){
echo $key." = ".$value. "<br/>";
};
}

在此之前有一个for循环获取响应并将其保存为我的xml文件夹中的.xml。我无法弄清楚我做错了什么，非常感谢帮助！我已经在这部分工作了8-9个小时。提前谢谢！

如果您想从xml获取属性，可以使用simplexml_load_file。

要循环<ns2:ItemAttributes..，您可以使用SimpleXMLElement children方法和相应的命名空间“ns2”

也许这个获得一些属性的例子可以帮到你：

$xml = simplexml_load_file($xmlFilePath);
$ns = $xml->getNamespaces(true);

$asin = '';
$salesRankings = array();
$amount = '';

foreach ($xml->Products->Product as $product) {
    $asin = (string)$product->Identifiers->MarketplaceASIN->ASIN;

    foreach ($product->SalesRankings->SalesRank as $salesRank) {
        $salesRankings[] = array(
            "ProductCategoryId" => (string)$salesRank->ProductCategoryId,
            "Rank" => (string)$salesRank->Rank
        );
    }
    foreach ($product->AttributeSets->children($ns['ns2']) as $itemAttributes) {
        $amount = (string)$itemAttributes->ListPrice->Amount;
    }
}
