标签： php xml parsing

我正在构建一个产品Feed，我遇到了一些问题，需要提取一个位于xml代码深处的xml值。

XML代码是:(对于这个问题，我清理了无关的值）

    <ns2:HotelListResponse xmlns:ns2="http://v3.hotel.wsapi.ean.com/">

    endforeach;

    echo "</ul>";


    ?>

所有代码都正常运行并按预期执行。 执行该行：

    $chargerate= $data->RoomRateDetailsList->RoomRateDetails->RateInfo->ChargeableRateInfo['total'];

有人可以向我解释我做错了吗？

2 个答案:

答案 0 :(得分：1)

而不是

$chargerate= $data->RoomRateDetailsList->RoomRateDetails->RateInfo->ChargeableRateInfo['total'];

使用

$chargerate= $info->RoomRateDetailsList->RoomRateDetails->RateInfo->ChargeableRateInfo['total'];
             ^^^^^

$data包含整个回复，而您需要位于$data->HotelList->HotelSummary循环$info内的具体foreach()内。

也是行

$chargeableRateInfo = $rateInfo->ChargeableRateInfo['total'];

看起来很可疑，因为变量$rateinfo未在任何地方设置，它应该引用$info->RoomRateDetailsList->RoomRateDetails->RateInfo ...
