Question

我正在使用Amazon API获取产品详细信息。我有一个这样的xml输出文件。我正在尝试解析xml代码以获取值。但是它只对某些对象有效，而对另一些对象无效。

<ItemLookupResponse
xmlns="http://webservices.amazon.com/AWSECommerceService/2011-08-01">
<OperationRequest>...</OperationRequest>
<Items>
    <Request>
        <IsValid>True</IsValid>
        <ItemLookupRequest>
            <IdType>ASIN</IdType>
            <ItemId>B008593O8S</ItemId>
            <ResponseGroup>Images</ResponseGroup>
            <ResponseGroup>ItemAttributes</ResponseGroup>
            <ResponseGroup>Offers</ResponseGroup>
            <VariationPage>All</VariationPage>
        </ItemLookupRequest>
    </Request>
    <Item>
        <ASIN>B008593O8S</ASIN>
        <DetailPageURL>

`

例如，

$pxml = simplexml_load_string($response);
$title = $pxml->Items->Item->DetailPageURL; //Working

$link = $pxml->Items->Item->SmallImage->URL; //Not working

还有其他可用的方法吗？谢谢！

无法使用simplexml_load_string函数从xml获取所有值
