XSLT 代码 - 为每 3 xml 段创建一个新的 XML 段

Question

我仍在学习和提高我的 XSLT 技能。但希望我能从专家那里看到我的要求没关系。

对于每 3 条记录 xml 段，将在顶部创建一个新记录 xml 段，该段将计算 3 条记录的总和。然后，新记录 (PK50) 段仍将产生多余的或剩余的行项目。请参阅下面的示例数据。已创建 PK50 条记录，其中最后一条包含剩余 2 条记录的总和。

PostingKey 50表示新创建的记录，每3条记录的金额总和。 Account 字段也将具有值“Summation”。感谢您的任何意见。非常感谢！

到目前为止，这是我正在使用的当前代码。唯一的问题是 Amt_DocCurr 和 Amt_LocCurr 中金额的总和。感谢任何输入来处理这个问题并将其合并到我当前的代码中。

Answer 1

这里有一个方法可以做到这一点：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="2.0">

  <xsl:output method="xml" indent="yes"/>

  <xsl:template match="/">
    <AccrualReportOutput>
      <xsl:apply-templates select="AccrualReport/Record[position() mod 2 = 0]"/>
    </AccrualReportOutput>
  </xsl:template>
  
  <xsl:template match="Record">
    <xsl:variable name="group" select=". | preceding-sibling::Record[1]"/>
    <!-- Create new Summation Record -->
    <xsl:copy>
      <xsl:copy-of select="* except (Account, PostingKey, Amt_DocCurr, Amt_LocCurr)"/>
      <Account>Summation</Account>
      <PostingKey>50</PostingKey>
      <Amt_DocCurr><xsl:value-of select="sum($group/Amt_DocCurr)"/></Amt_DocCurr>
      <Amt_LocCurr><xsl:value-of select="sum($group/Amt_LocCurr)"/></Amt_LocCurr>
    </xsl:copy>
    <!-- Copy 2 Records of group -->
    <xsl:copy-of select="$group"/>
  </xsl:template>
  
</xsl:stylesheet>

看到它在这里工作：https://xsltfiddle.liberty-development.net/aB9NKz/1
