Question

我正在使用SimpleXML框架来解析我的Android应用程序中的xmls。我在解析@ElementList时遇到问题。

xml的片段：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<SaleToPOIResponse>
    <MessageHeader (...) />
    <ReconciliationResponse  ReconciliationType="SaleReconciliation">
        <Response Result="Success"/>
        <TransactionTotals PaymentInstrumentType="Card">
            <PaymentTotals TransactionType="Debit" TransactionCount="182" TransactionAmount="4.17"/>
            <PaymentTotals TransactionType="Credit" TransactionCount="1" TransactionAmount="2.01"/>
        </TransactionTotals>
    </ReconciliationResponse>
</SaleToPOIResponse>

我的课程看起来：

ReconciliationResponseType.java：

 @Root
    @Order(elements = {
            "Response",
            "TransactionTotals"
    })
    public class ReconciliationResponseType {

        @Element(name = "Response", required = true)
        protected ResponseType response;
        @ElementList(name = "TransactionTotals", inline = true, required = false)
        protected List<TransactionTotalsType> transactionTotals;
        @Attribute(name = "ReconciliationType", required = true)
        protected String reconciliationType;

    // getters and setters
    }

TransactionTotalsType.java：

  @Root
    @Order(elements = {
           "PaymentTotals",
           "LoyaltyTotals"
    })
    public class TransactionTotalsType {

        @ElementList(name = "PaymentTotals", inline = true, required = false)
        protected List<PaymentTotalsType> paymentTotals;
        @Attribute(name = "PaymentInstrumentType", required = true)
        protected String paymentInstrumentType;

    // getters and setters
    }

我使用方法解析它：

public static SaleToPOIResponse fromXMLString(String xmlResponse) {
    Reader reader = new StringReader(xmlResponse);

    Serializer serializer = new Persister();
    try {
        SaleToPOIResponse response = serializer.read(SaleToPOIResponse.class, reader, false);
        return response;
    } catch (Exception e) {
        Log.e(TAG, "Exception during parsing String XML to SaleToPOIResponse: ", e);
    }
    return null;
}

但每次我得到一个例外，那个有序元素＆＃39; TransactionTotals＆＃39;缺少，即使1）它不是必需的2）它确实存在于解析的xml

中

org.simpleframework.xml.core.ElementException: Ordered element 'TransactionTotals' missing for class pl.novelpay.epas.generated.saletopoimessages.ReconciliationResponseType

当我评论＆＃39; TransactionTotals＆＃39;从@Order中解析xml没有异常，但结果中的TransactionTotals为空。我在这里错过了什么？

我在阅读类似问题的答案时发现了什么问题： https://sourceforge.net/p/simple/mailman/message/25699359/

我使用{{{(.*?)}}} name {}所以ElementList属性应如下所示：

现在它完美无缺。

Android - SimpleXML框架无法解析@ElementList
