Tek bir dize sonucunu almak için SimpleXMLElement üzerinde XPath kullanarak

0 Cevap

Ben bir GoogleCheckout tepki bazı verileri almak için çalışıyorum. Ben veri aramak için bir SimpleXMLElement ve XPath'i kullanıyorum. Sorunlardan biri xpath gelen yanıt SimpleXMLElement bir dizi olmasıdır - Ben istiyorum tüm dize veridir. Örneğin, <email> en az iki kez gösterilen ama sadece bir ateşten sonuç istiyorsun - Diğer tepkisi TAG adı multilpe örneğini içerebilir olmasıdır.

İşte ben bugüne kadar ne var

            $notifyData = array();
            $notifyData['buyerEmail'] = $data->xpath('buyer-billing-address//email')[0];
            $notifyData['buyerName'] = $data->xpath('buyer-billing-address//contact-name');
            $notifyData['transactionId'] = $data->xpath('/new-order-notification/google-order-number');
            $notifyData['itemName'] = $data->xpath('//item-name');
            $notifyData['amount'] = $data->xpath('//unit-price');
            $notifyData['currency'] = $notifyData['amount'][0]['currency'];//$data->xpath('//@currency[1]');

Burada $ notifyData üzerindeki print_r gelen yanıt () olduğunu

Array
(
    [buyerEmail] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [0] => sandbox@mysite.com
                )

        )

    [buyerName] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [0] => Mr Sandbox Buyer
                )

        )

    [transactionId] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [0] => 271578474675716
                )

        )

    [itemName] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [0] => My Item
                )

        )

    [amount] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [currency] => USD
                        )

                    [0] => 3.99
                )

        )

    [currency] => SimpleXMLElement Object
        (
            [0] => USD
        )

)

Veri print_r sonra bu gibi göstermek () için ne i istiyorum

Array
(
    [buyerEmail] => sandbox@mysite.com
    ...
    [currency] => USD
