想在 XSLT 中递归地求和每行的关键数量

Question

我对每一行使用键匹配进行了一些计算，我希望在最后一行对这些值的总和进行求和。下面是计算。

LINE#1

4 (DispatchQuantity = 2; occurrence = 2 -> 2 x 2 = 4)      MID-LAYER          12   (UnitNetWeight = 3KG x 12)
4 (DispatchQuantity = 2; occurrence = 2 -> 2 x 2 = 4)      PALLET-LAYER       12   (UnitNetWeight = 3KG x 12)

LINE#2

8 (DispatchQuantity = 4; occurrence = 2 -> 4 x 2 = 8)      MID-LAYER          24   (UnitNetWeight = 3KG x 8)

我需要添加每行的数字以生成最后一个块，其中应包含 16 (4+4+8) 和 48(12+12+24)

当前o/p:
4 中层 12
4 托盘层 12
8 中层 24

考虑这个简化的示例：

XSLT 1.0（+EXSLT 节点集（）函数）

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common"
extension-element-prefixes="exsl">
<xsl:output method="text" encoding="UTF-8"/>

<xsl:key name="aux" match="Item[Code='auxiliary']" use="concat(CodeIdentifier, '|', generate-id(..))"/>

<xsl:template match="cXML">

    <xsl:variable name="groups-RTF">
        <xsl:for-each select="//Item[Code='auxiliary'][count(. | key('aux', concat(CodeIdentifier, '|', generate-id(..)))[1]) = 1]"> 
            <group code="{CodeIdentifier}">
                <xsl:variable name="group-size" select="count(key('aux', concat(CodeIdentifier, '|', generate-id(..))))"/>
                <xsl:variable name="quantity" select="DispatchQuantity/@quantity * $group-size"/>
                <quantity>
                    <xsl:value-of select="$quantity"/>
                </quantity>
                <weight>
                    <xsl:value-of select="Dimension[@type='unitNetWeight']/@quantity * $quantity"/>
                </weight>
            </group>
        </xsl:for-each>
    </xsl:variable>
    
    <xsl:variable name="groups" select="exsl:node-set($groups-RTF)/group" />    

    <!-- output -->
    <xsl:text>code, quantity, weight&#10;</xsl:text>
    <xsl:for-each select="$groups">
        <xsl:value-of select="@code"/>
        <xsl:text>, </xsl:text>
        <xsl:value-of select="quantity"/>
        <xsl:text>, </xsl:text>
        <xsl:value-of select="weight"/>
        <xsl:text>&#10;</xsl:text>
    </xsl:for-each>
    <xsl:text>TOTAL, </xsl:text>
    <xsl:value-of select="sum($groups/quantity)"/>
    <xsl:text>, </xsl:text>
    <xsl:value-of select="sum($groups/weight)"/>
</xsl:template>

</xsl:stylesheet>

结果

code, quantity, weight
MID-LAYER, 4, 12
PALLET-LAYER, 4, 12
MID-LAYER, 8, 24
TOTAL, 16, 48
