Question

您好我正在使用SwiftyXMLParser从服务器解析xml响应。我可以成功解析单个xml，但是数组值有问题。总是没事了

这是我的样本xml

<ItemTrackingDetailsResponse xmlns="http://singpost.com/paw/ns" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">

    <Status>
        <ErrorCode>0</ErrorCode>
        <ErrorDesc>Success</ErrorDesc>
    </Status>
</ItemTrackingDetailsResponse>

我可以通过

获得单件商品

print(xml!["ItemTrackingDetailsResponse","ItemsTrackingDetailList","ItemTrackingDetail","ItemType"].text)

但是对于数组我无法获得细节。如何访问阵列成员？任何帮助都非常感激。感谢

                    <DeliveryStatusDetail>
                        <StatusDescription>Recovered item from POPStation for service recovery</StatusDescription>

您可以按如下方式访问Child Array内容：

print(xml["ItemTrackingDetailsResponse","ItemsTrackingDetailList","ItemTrackingDetail","DeliveryStatusDetails","DeliveryStatusDetail",0,"Location"].text)

"DeliveryStatusDetail",0表示您要访问第0个位置DeliveryStatusDetail元素。

枚举数组：

for DeliveryStatusDetail in xml["ItemTrackingDetailsResponse","ItemsTrackingDetailList","ItemTrackingDetail","DeliveryStatusDetails","DeliveryStatusDetail"] {
    print(DeliveryStatusDetail["Location"].text)
}

IOS Swift使用SwiftyXMLParser解析XML数组时出错
