1)如果在 2 个不同的策略上有多个实例具有 CategoryCd = GL AND selectedInd = 'Y' AND deletedInd = 'Y'，则 FAIL 并返回代码 FAILURE 和返回原因代码 MANYPOL

2) 如果在同一策略上有多个具有基础策略类别 Cd = GL AND selectedInd = 'Y' 和 deletedInd = 'Y' 的实例，则 FAIL 并返回代码 FAILURE 并返回原因代码 MANY

3) 如果 MANYPOL 和 MANY 条件都为真，则应返回 MANYPOL（这意味着您可以先检查 MANYPOL 条件，如果为真，则可以停止处理并返回

4)如果没有底层PolicyCategoryCd = GL AND selectedInd = 'Y' AND deletedInd = 'Y' 的实例，则返回代码= SUCCESS 并返回原因代码NOCHANGE

测试用例 3 - 2 个 GL 政策，每个政策有 2 个报价版本。策略 22 版本 1 选择了 Ind = 'Y' AND deletedInd = 'Y'，策略 11 版本 1 选择了 Ind = 'Y' AND deletedInd = 'N'。其他 2 个版本已 selectedInd = 'N' AND deletedInd = 'Y'。最终结果应该是 Policy 22 version 1 has selectedInd = 'Y' AND deletedInd = 'N' 并且 policy 11 version 1 has selectedInd = 'N' AND deletedInd = 'Y'。

【问题讨论】：

不谈细节，你得到的输出是什么？哪种情况不起作用？
我得到第二个场景输出，但不是 1 和 3。

标签： xml xslt xslt-1.0

【解决方案1】：

您的样式表看起来不仅仅是检查“MANYPOL”和“MANY”，但我将只关注手头的任务......

考虑使用键通过相关指标查找underlyingPolicy元素

<xsl:key name="policy" 
         match="underlyingPolicy" 
         use="concat(CategoryCd, '|', selectedInd, '|', deletedInd)" />

然后，您可以测试是否有两个具有相同指标的不同保单编号，如下所示：

<xsl:when test="linesOfInsurance/underlyingPolicy
                   [PolicyNo != key('policy', concat(CategoryCd, '|', selectedInd, '|', deletedInd))/PolicyNo]">

这会给你MANYPOL 结果。

现在，您可能想通过将“不等于”更改为“等于”来检查 MANY

<xsl:when test="linesOfInsurance/underlyingPolicy
                   [PolicyNo = key('policy', concat(CategoryCd, '|', selectedInd, '|', deletedInd))/PolicyNo]">

但这不起作用，因为它会将当前的underlyingPolicy 元素与自身匹配！相反，创建第二个密钥，其中包含 PolicyNo

<xsl:key name="policy_with_no" 
         match="underlyingPolicy" 
         use="concat(PolicyNo, '|', CategoryCd, '|', selectedInd, '|', deletedInd)" />

然后你可以检查是否有多个相同数量的策略共享相同的指标，像这样：

 <xsl:when test="linesOfInsurance/underlyingPolicy
                    [key('policy_with_no', concat(PolicyNo, '|',CategoryCd, '|', selectedInd, '|', deletedInd))[2]]">

通过使用xsl:choose，首先评估第一个xsl:when，因此将始终输出MANYPOL，即使MANY 也是如此。

试试这个 XSLT

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" >
    <xsl:output method="xml" indent="yes" />

    <xsl:key name="policy" match="underlyingPolicy" use="concat(CategoryCd, '|', selectedInd, '|', deletedInd)" />
    <xsl:key name="policy_with_no" match="underlyingPolicy" use="concat(PolicyNo, '|', CategoryCd, '|', selectedInd, '|', deletedInd)" />

    <xsl:template match="/policy">
        <PWResponse>
            <xsl:choose>
                <xsl:when test="linesOfInsurance/underlyingPolicy[PolicyNo != key('policy', concat(CategoryCd, '|', selectedInd, '|', deletedInd))/PolicyNo]">
                    <ReturnCode>FAILURE</ReturnCode>
                    <ReturnReasonCode>MANYPOL</ReturnReasonCode>
                </xsl:when>
                <xsl:when test="linesOfInsurance/underlyingPolicy[key('policy_with_no', concat(PolicyNo, '|',CategoryCd, '|', selectedInd, '|', deletedInd))[2]]">
                    <ReturnCode>FAILURE</ReturnCode>
                    <ReturnReasonCode>MANYPOL</ReturnReasonCode>
                </xsl:when>
                <xsl:otherwise>
                    <ReturnCode>SUCCESS</ReturnCode>
                    <ReturnReasonCode></ReturnReasonCode>
                </xsl:otherwise>
            </xsl:choose>
        </PWResponse>
    </xsl:template>
</xsl:stylesheet>

【讨论】：

非常感谢蒂姆。我明白了这个概念，还有 3 个案例让我很困惑。你也能帮忙吗。我将添加输入和预期输出。
如果你能把你的问题放回原来的样子，并在你的新案例中提出一个全新的问题，这可能会更好。谢谢。
谢谢蒂姆，将用新的测试用例放回问题。
嗨蒂姆，请检查我已添加所有测试用例。非常感谢您的帮助
我的意思是将新案例放在一个全新的问题中。最初的问题已被回答并接受，因此在此阶段添加新案例会令人困惑。谢谢！
