XSLT 1.0 根据兄弟记录参数更改记录的输出答案

【问题标题】：XSLT 1.0 Change output of record based on sibling record parameterXSLT 1.0 根据兄弟记录参数更改记录的输出
【发布时间】：2017-06-24 03:26:19
【问题描述】：

我有一个传入的 XML 文件，其中包含我需要稍微转换的参与者和依赖项列表，因此依赖项信息作为子记录附加到参与者信息中，并且参与者记录的 EN_PLAN_TYPE 节点获取一个基于参与者有多少家属以及他们的关系的值。

要求

为每个与 PT_PARTICIPANT_FILE_IMP_ID 匹配的 DP_PARTICIPANT_FILE_IMP_ID 创建一个新的 Dependent_Record，它是 Eligibility_Detail_Record 的子记录
为每条具有 EN_PLAN_NAME 的“健康报销安排”的记录添加一个 EN_PLAN_TYPE 字段，内容如下：
- “Ind”（如果未找到依赖项）
- “IndSpouse”如果一个且只有一个受抚养人具有 DP_RELATIONSHIP 的配偶
- “IndChild”如果一个且只有一个具有 DP_RELATIONSHIP of Dependent
- “家庭”（如果有多个受抚养人）

问题是 DP_RELATIONSHIP 正在针对特定参与者的每个 ELIGIBILITY_DETAIL_RECORD 的第一次出现进行测试，该参与者始终为空白。我只是不确定如何轻松调整它以针对存在依赖项的记录（DP_DEPENDENT_FILE_IMP_ID）和 participantCount 为 1（我可能应该将变量重命名为dependentCount，但我稍后会担心）

请在此处完整描述您当前的问题，而不是链接到上一个问题。从您的问题来看，尚不清楚预期和实际输出是什么，并且您的部分代码丢失了。如果我们首先需要阅读和理解上一个问题和它的答案，那么很难理解你在问什么。

【解决方案1】：

我建议只收集家属，而不是用钥匙收集所有参与者。

首先模板顶级记录，然后使用键 EN_PLAN_TYPE 和 Dependent_Record 元素：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output indent="yes" omit-xml-declaration="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:key name="dependents" match="Eligibility_Detail_Record" use="DP_PARTICIPANT_FILE_IMP_ID"/>

    <xsl:template match="/*">
        <xsl:copy>
            <xsl:apply-templates select="Eligibility_Detail_Record[not(DP_PARTICIPANT_FILE_IMP_ID)]"/>
        </xsl:copy>
    </xsl:template>

    <!-- Template top level records -->
    <xsl:template match="Eligibility_Detail_Record[not(DP_PARTICIPANT_FILE_IMP_ID)]">
        <xsl:copy>
            <xsl:copy-of select="*[starts-with(name(),'PT_')]|EN_PLAN_NAME"/>
            <!--Add an EN_PLAN_TYPE field for each Record that has an EN_PLAN_NAME of "Health Reimbursement Arrangement" -->
            <xsl:if test="EN_PLAN_NAME='Health Reimbursement Arrangement'">
                <xsl:call-template name="HRA"/>
            </xsl:if>
            <xsl:copy-of select="*[not(self::EN_PLAN_NAME) and starts-with(name(),'EN_')]"/>
            <xsl:apply-templates select="key('dependents', PT_PARTICIPANT_FILE_IMP_ID)"/>
        </xsl:copy>
    </xsl:template>

    <!-- Template dependent records -->
    <xsl:template match="Eligibility_Detail_Record[DP_PARTICIPANT_FILE_IMP_ID]">
        <Dependent_Record>
            <xsl:copy-of select="*[starts-with(name(), 'DP_')]"/>
        </Dependent_Record>
    </xsl:template>

    <!-- Plan type -->
    <xsl:template name="HRA">
        <xsl:variable name="dependents" select="key('dependents', PT_PARTICIPANT_FILE_IMP_ID)"/>
        <xsl:variable name="participantCount" select="count($dependents)"/>
        <EN_PLAN_TYPE>
            <xsl:choose>
                <!--"Family" if more than one dependent-->
                <xsl:when test="$participantCount > 1">Family</xsl:when>
                <!--"IndChild" if one and only one dependent that has DP_RELATIONSHIP of Dependent-->
                <xsl:when test="$participantCount = 1 and $dependents/DP_RELATIONSHIP = 'Dependent'">IndChild</xsl:when>
                <!--"IndSpouse" if one and only one dependent that has DP_RELATIONSHIP of Spouse-->
                <xsl:when test="$participantCount = 1 and $dependents/DP_RELATIONSHIP = 'Spouse'">IndSpouse</xsl:when>
                <!--"Ind" if no dependents are found-->
                <xsl:when test="$participantCount = 0">Ind</xsl:when>
            </xsl:choose>
        </EN_PLAN_TYPE>
    </xsl:template>

这个答案现在对我来说似乎很明显。盯着一个问题看太久真的会打乱思维过程。感谢您的帮助！
