对 XSL 1.0 中的分组元素求和

Question

XSL 快把我逼疯了，我希望有人能帮我解决这个问题。代码已准备好复制粘贴。

我正在 XSL 1.0 中进行分组，我希望对所有分组的 'Amount' 元素求和。

我的数据是这样的。

<CustInvoiceTable class="entity">
    <McsCmBilCalcInvoiceLine class="entity">
        <Amount>0.05</Amount>
        <ItemId>ITM-0000088</ItemId>

</CustInvoiceTable>

以及 XSL：

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="Lines-by-ItemId" match="CustInvoiceTable/McsCmBilCalcInvoiceLine" use="CustInvoiceTable/McsCmBilCalcInvoiceLine/ItemId" />

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

    <xsl:template match="/">

        <root>

            <xsl:for-each select="CustInvoiceTable/McsCmBilCalcInvoiceLine[count(. | key('Lines-by-ItemId', ItemId)[1]) = 1][McsCmBilProductItem/CgiBundleLines = 1][not(ItemId = preceding-sibling::McsCmBilCalcInvoiceLine/ItemId)]">
                <xsl:sort select="ItemId" />
                <GroupInvoiceLine>
                    <ItemId><xsl:value-of select="ItemId" /></ItemId>
                    <SumAmount><xsl:value-of select="sum(Amount)"/></SumAmount> <!-- This does not work -->
                </GroupInvoiceLine>
            </xsl:for-each>

        </root>

    </xsl:template>

</xsl:stylesheet>

结果：假设我们按 "ITM-0000088" 分组，我希望结果为 0.12。目前它只是抓取第一条记录。

如果我们在 "ITM-0000083" 上分组，我希望总和为 6.69 + 7.96 = 14.65 而不是自上次 'McsCmBilCalcInvoiceLine' 和 'ItemId = ITM-0000083' 以来的 6.69 + 7.96 + -0.66 = 13.99 'McsCmBilProductItem'.

中没有 'CgiBundleLines = 1'

Answer 1

首先，您的密钥应定义为：

<xsl:key name="Lines-by-ItemId" match="McsCmBilCalcInvoiceLine" use="ItemId" />

然后更改：

<SumAmount><xsl:value-of select="sum(Amount)"/></SumAmount>

至：

<SumAmount><xsl:value-of select="sum(key('Lines-by-ItemId',ItemId)/Amount)"/></SumAmount>

Answer 2

将键定义为 <xsl:key name="Lines-by-ItemId" match="CustInvoiceTable/McsCmBilCalcInvoiceLine" use="ItemId" />，因为 use 属性值是相对于匹配节点计算的。

然后先看看如何使用key和Muenchian分组，使用

        <xsl:for-each select="CustInvoiceTable/McsCmBilCalcInvoiceLine[count(. | key('Lines-by-ItemId', ItemId)[1]) = 1]">
            <xsl:sort select="ItemId" />
            <GroupInvoiceLine>
                <ItemId><xsl:value-of select="ItemId" /></ItemId>
                <SumAmount><xsl:value-of select="sum(key('Lines-by-ItemId', ItemId)/Amount)"/></SumAmount> 
            </GroupInvoiceLine>
        </xsl:for-each>

至于其他条件，考虑将其包含在关键模式中：

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="Lines-by-ItemId" match="CustInvoiceTable/McsCmBilCalcInvoiceLine[McsCmBilProductItem/CgiBundleLines = 1]" use="ItemId" />

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

    <xsl:template match="/">

        <root>

            <xsl:for-each select="CustInvoiceTable/McsCmBilCalcInvoiceLine[McsCmBilProductItem/CgiBundleLines = 1][count(. | key('Lines-by-ItemId', ItemId)[1]) = 1]">
                <xsl:sort select="ItemId" />
                <GroupInvoiceLine>
                    <ItemId><xsl:value-of select="ItemId" /></ItemId>
                    <SumAmount><xsl:value-of select="sum(key('Lines-by-ItemId', ItemId)/Amount)"/></SumAmount> 
                </GroupInvoiceLine>
            </xsl:for-each>

        </root>

    </xsl:template>

</xsl:stylesheet>
