PHP simplexml和xpath访问节点值

标签： php xpath xml-parsing simplexml

我有来自UPS Rates API的以下XML响应，我需要为RateType节点='RATED_ACCOUNT_SHIPMENT'获取每个'RateReplyDetails'的'ServiceType'，'Amount'和'Currency'节点的值。

我的尝试如下，ServiceType有效，但不是金额和货币。有人可以帮忙吗？

$RateReply = $fedex_xml->children("env", true)->Body->children("v13", true)->RateReply;

 foreach($RateReply->RateReplyDetails as $details){
    $service = $details->ServiceType;
    $amount = $details->xpath("/RatedShipmentDetails/ShipmentRateDetail/RateType['RATED_ACCOUNT_SHIPMENT']/TotalNetCharge/Amount");
    $currency = $details->xpath("/RatedShipmentDetails/ShipmentRateDetail/RateType['RATED_ACCOUNT_SHIPMENT']/TotalNetCharge/Currency");

 }

//amount
"/RatedShipmentDetails/ShipmentRateDetail[RateType = 'RATED_ACCOUNT_SHIPMENT']/TotalNetCharge/Amount"

//currency
"/RatedShipmentDetails/ShipmentRateDetail[RateType = 'RATED_ACCOUNT_SHIPMENT']/TotalNetCharge/Currency"

xpath的来源：doc examples

更新

foreach ($fedex_xml->xpath("//RateReply//RateReplyDetails") as $details) {

    $amounts = $details->xpath("./RatedShipmentDetails/ShipmentRateDetail[RateType = 'RATED_ACCOUNT_SHIPMENT']/TotalNetCharge/Amount");
    $currencies = $details->xpath("./RatedShipmentDetails/ShipmentRateDetail[RateType = 'RATED_ACCOUNT_SHIPMENT']/TotalNetCharge/Currency");

    var_dump($amounts);
    var_dump($currencies);
}

我使用xpath表达式来选择每个RateReplyDetails，然后使用其他一些xpath表达式来提取值。请注意，这些部分开头的./部分非常重要，它表示解释当前作用域中的xpath表达式（RateReplyDetails节点）。
