Question

见下文，XML body 我有：

我需要获取每个条目的值：ItemCode & Price。

我试着这样做： $data = simplexml_load_string($xml)，但是当我执行 print_r($data->entry) 时，这是我得到的：

SimpleXMLElement Object
(
    [id] => https://start.exactonline.be/api/v1/393999/sync/logistics/SalesItemPrices(2781117417L)
    [title] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [type] => text
                )

        )

    [updated] => 2021-08-11T13:47:01Z
    [author] => SimpleXMLElement Object
        (
            [name] => SimpleXMLElement Object
                (
                )

        )

    [link] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [rel] => edit
                    [title] => SalesItemPriceSync
                    [href] => SalesItemPrices(2781117417L)
                )

        )

    [category] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [term] => Exact.Web.Api.Models.Sync.Logistics.SalesItemPriceSync
                    [scheme] => http://schemas.microsoft.com/ado/2007/08/dataservices/scheme
                )

        )

    [content] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [type] => application/xml
                )

        )

)

但我希望有： OX11213001-M61 136.36 在“内容”部分。

那么，我怎样才能得到这些值呢？以及如何正确地在这些所有“条目”之间进行循环？

我试过 foreach ($products->entry as $product) 但收到错误：警告：为 foreach()

提供的参数无效

以下似乎有效。请注意，您的元素是命名空间-d 并且有一个前缀。

$simpleXML = new SimpleXMLElement($xml);
$myResult  = [];

foreach($simpleXML->entry as $entry) {
$properties = $entry->content->children('m', true);
$myResult[] = ['itemCode' => (string) $properties->children('d', true)->ItemCode, 'itemPrice' => (string) $properties->children('d', true)->Price];
}

print_r($myResult); // to see the values

PHP - 从 XML 内容获取值
