如何使用 Group By 子句

Question

我正在尝试为 XML 数据实现 XSLT 映射。

这是我要找的东西。

输入XML:

    <ListOfPersons xmlns="http://ws.wso2.org/dataservice">
  <PersonDisclosureDate>
     <Emplid>123456</Emplid>
     <uniqname>abcd</uniqname>

我尝试使用 ALtova Mapforce 工具来映射 xml 但没有得到正确的结果。

Altova 映射：

有人可以提供一些指导，说明如何使用 Altova Mapforce 或什至使用 group by 标签的普通 XSLT 文档来实现上述结果吗？

提前致谢，克兰西

这似乎是一个简单的 for-each-group 选择 PersonDisclosureDate 并按 uniqname 分组。

为了简单起见，这里有一个使用拉取方法的基本示例...

XSLT 2.0（此处的工作示例：http://xsltfiddle.liberty-development.net/nbUY4kp）

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xpath-default-namespace="http://ws.wso2.org/dataservice">
  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="/*">
    <DisclosureData xsi:noNamespaceSchemaLocation="C:/XSL/eResearch_Expected_Response.xsd" 
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <count><xsl:value-of select="count(distinct-values(/*/PersonDisclosureDate/uniqname))"/></count>
      <xsl:for-each-group select="PersonDisclosureDate" group-by="uniqname">
        <disclosures>
          <uniqName><xsl:value-of select="current-grouping-key()"/></uniqName>
          <hasDisclosed><xsl:value-of select="current-group()[1]/HasDisclosed"/></hasDisclosed>
          <lastDiscloseDt><xsl:value-of select="current-group()[1]/LastDiscloseDt"/></lastDiscloseDt>
          <xsl:for-each select="current-group()">
            <disclosureRecords>
              <oeId><xsl:value-of select="oeID"/></oeId>
              <oeName><xsl:value-of select="oeName"/></oeName>
              <oeSignDate><xsl:value-of select="oeSignDate"/></oeSignDate>
              <oeRelationship><xsl:value-of select="relationship"/></oeRelationship>
              <oeTypes><xsl:value-of select="Types"/></oeTypes>
              <oeStartDt><xsl:value-of select="startdt"/></oeStartDt>
              <oeEndDt><xsl:value-of select="enddt"/></oeEndDt>
            </disclosureRecords>
          </xsl:for-each>            
        </disclosures>
      </xsl:for-each-group>
    </DisclosureData>
  </xsl:template>

</xsl:stylesheet>
