XSL快把我逼疯了，我希望有人能帮我解决这个问题。代码已准备好进行复制粘贴

我在XSL 1.0中做一个group by，我希望对所有分组的“Amount”元素求和

和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>
结果是： 假设我们在“ITM-0000088”上分组，我预计结果为0.12。目前它只获得了第一条记录

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6.69+7.96+-0.66=13.99，因为最后一个带有“ItemId=ITM-0000083”的“mcscmbilconvoiceline”在其“McsCmBilProductItem”中没有“cgibundlines=1”。

首先，您的密钥应定义为：

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

<SumAmount><xsl:value-of select="sum(Amount)"/></SumAmount>
致：
将键定义为
，因为
使用
属性值是相对于匹配节点计算的

然后，要首先了解如何使用键和Muenchian分组，请使用

        <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，考虑将其包含在键模式内：

<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>
又是一份出色的工作。谢谢。这不会产生想要的结果。它没有考虑到只有“CGIBundlines=1”的行才应该分组。无论如何，谢谢。@Lange您可以将谓词添加到要求和的组中。（同时问一件以上的事情不是一个好策略）谢谢你，迈克尔。你可能是对的。我以后会避免这样做。这里有很多代码。请发布一个最小的、完整的、可验证的示例（）是-下次我将减少数据量。非常感谢。
