2.0 版本的 XSLT 分组

问题描述 投票：0回答：1

想知道如何在 XSLT 中创建多个分组。以下 XML 应按 memberID、存款日期和存款类型分组。每个会员的总金额应按日期和存款类型求和。我已经提出了这个问题，答案在 3.0 版本中。我需要一个使用 XSLT 2.0 版的解决方案，因为我正在使用的系统对 3.0 版有限制。谢谢你，.

最终结果应该是：

   MemberID|DepositDate|DepositType|Amount
   12345|2023-11-22|CHK|60
   12345|2023-11-22|SAV|35
   12345|2023-12-05|CHK|25
   12345|2023-12-05|SAV|10
   78910|2023-11-22|CHK|10
   78910|2023-11-22|SAV|30
   78910|2023-12-05|CHK|25
   78910|2023-12-05|SAV|20

我尝试根据日期和存款类型运行 for-each-group，但这不起作用。请参阅下面的 XSLT。

    <xsl:choose>
        
        <xsl:when test="exists(DepositInfo)">
            
            <xsl:for-each-group select="." group-by="DepositDate">
    
                <xsl:variable name="DepositDateOfCurrentGroup" select="current-grouping-key()"/>
                
                <!-- MemberID --><xsl:value-of select="MemberID"/>
                <xsl:value-of select="$vPipeDelimiter"/>
                <!-- DepositDate --><xsl:value-of select="format-date($DepositDateOfCurrentGroup,'[Y0001][M01][D01]')"/>
                <xsl:value-of select="$vPipeDelimiter"/>        
                
                
                <!-- DepositType -->                   
                <xsl:choose>
                    <xsl:when test="DepositInfo/DepositType = 'CHK'">
                        <!-- Amount --><xsl:text>ACCT1</xsl:text>
                    </xsl:when>
                    <xsl:when test="DepositInfo/DepositType = 'SAV'">
                        <!-- Amount --><xsl:text>ACCT2</xsl:text>
                    </xsl:when>
                    <xsl:when test="DepositInfo/DepositType = 'CD'">
                        <!-- Amount --><xsl:text>ACCT3</xsl:text>
                    </xsl:when>
                    <xsl:otherwise>
                        <xsl:text/>
                    </xsl:otherwise>
                </xsl:choose>
                <xsl:value-of select="$vPipeDelimiter"/>
                     
                
                
                <xsl:choose>
                  
                    <xsl:when test="exists(DepositDate = $DepositDateOfCurrentGroup and DepositInfo/DepositType = 'CHK')">
                        <xsl:value-of select="format-number(sum(DepositDate[DepositDate = $DepositDateOfCurrentGroup]/Amount),'#######0.00')"/>                                 
                    </xsl:when>
                    <xsl:when test="exists([DepositDate = $DepositDateOfCurrentGroup and DepositInfo/DepositType = 'SAV'])">
                        <xsl:value-of select="format-number(sum(DepositDate[DepositDate = $DepositDateOfCurrentGroup]/Amount),'#######0.00')"/>                                 
                    </xsl:when>
                    <xsl:when test="exists(DepositDate = $DepositDateOfCurrentGroup and DepositInfo/DepositType = 'CD')">
                        <xsl:value-of select="format-number(sum(DepositDate[DepositDate = $DepositDateOfCurrentGroup]/Amount),'#######0.00')"/>                                 
                    </xsl:when>
                    <xsl:otherwise>
                        <xsl:text>0.00</xsl:text>
                    </xsl:otherwise>
                </xsl:choose>   
               
                         
                                                  
                <xsl:value-of select="$vLineFeed"/>
                
              
    
            </xsl:for-each-group>
        
        </xsl:when>
        
        <xsl:otherwise>                   
              
            
        </xsl:otherwise>
        
    </xsl:choose>
    
</xsl:template>

最终结果没有分组：

MemberID|DepositDate|DepositType|Amount|
12345|20231122|CHK|0.00
12345|20231122|CHK|0.00
12345|20231205|CHK|0.00
78910|20231122|CHK|0.00
78910|20231205|CHK|0.00
78910|20231205|CHK|0.00

xslt 2.0 似乎不支持

composite="yes"
。试试这个：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="2.0"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  exclude-result-prefixes="#all">

  <xsl:output method="text" />

  <xsl:template match="/">
    <xsl:for-each-group select="Report/Deposit_Data/DepositInfo" 
         group-by="string-join((../MemberID, ../DepositDate, DepositType), '|')">
      <xsl:value-of select="current-grouping-key(), sum(current-group()/Amount)" separator="|"/>
      <xsl:text>&#10;</xsl:text>        
    </xsl:for-each-group>
  </xsl:template>

</xsl:stylesheet>
