XSL 1.0 Count Distinct with "following:[element]" 并排除某些元素

Question

所以我一直在努力计算不同的元素。我有这个数据。代码已准备好复制粘贴。

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

    <McsCmBilCalcInvoiceLine class="entity">

    <!-- Excluding these 3 elements will result in the correct count -->
    <McsCmBilCalcInvoiceLine class="entity">

    <McsCmBilCalcInvoiceLine class="entity">
        <ItemId>ITM-0000098</ItemId>
    </McsCmBilCalcInvoiceLine>

</CustInvoiceTable>

我想计算 CgiBundleLines = 1 的不同 ItemId 值。结果必须是 11。我的 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="/">

        <CountOne><xsl:value-of select="count(CustInvoiceTable/McsCmBilCalcInvoiceLine[not(ItemId = following::ItemId) and McsCmBilProductItem/CgiBundleLines = 1])"/></CountOne>
        <CountOne><xsl:value-of select="count(CustInvoiceTable/McsCmBilCalcInvoiceLine[not(ItemId = following::ItemId) and McsCmBilProductItem/CgiBundleLines = 1 and boolean(McsCmBilProductItem) = 1])"/></CountOne>

    </xsl:template>

</xsl:stylesheet>

当我运行这时，我得到 8 的计数。看起来最后 3 个 McsCmBilCalcInvoiceLine 元素导致 ItemId 不被计算在内。计算这 3 returns 个计数 = 11，这就是我想要的。那么如何排除最后 3 个元素或使我的 XSL 代码不计算它们。

谢谢。

Answer 1

如果您使用单独的谓词 /CustInvoiceTable/McsCmBilCalcInvoiceLine[McsCmBilProductItem/CgiBundleLines = 1][not(ItemId = preceding-sibling::McsCmBilCalcInvoiceLine/ItemId)]，那么您只能计算那些具有 McsCmBilProductItem/CgiBundleLines = 1 条件的元素。

所以

count(/CustInvoiceTable/McsCmBilCalcInvoiceLine[McsCmBilProductItem/CgiBundleLines = 1][not(ItemId = preceding-sibling::McsCmBilCalcInvoiceLine/ItemId)])

给出 11。
