Question

我有一个发票xml，我需要对itemid进行分组/总和例如，对于ItemId 444，我需要一个lineamount为100 + 25 = 125，而ItemId 555 = 200 +15。您将要说的很多示例是如何执行的，但是我还有另一个要求。我还需要根据CustInvoiceTrans和TaxTrans之间加入的InventTransId字段（AABB / BBCC）对TaxTrans \ TaxAmounts和TaxTrans \ TaxBaseAmounts进行相同的分组和总和。

之前：

  <CustInvoiceJour class="entity">
          <CustInvoiceTrans class="entity">
            <InventTransId>AABB</InventTransId>
            <InvoiceId>SI100</InvoiceId>
            <ItemId>444</ItemId>
            <LineAmount>100</LineAmount>
          </CustInvoiceTrans>
          <CustInvoiceTrans class="entity">
            <InventTransId>BBCC</InventTransId>
            <InvoiceId>SI100</InvoiceId>
            <ItemId>444</ItemId>
            <LineAmount>25</LineAmount>
          </CustInvoiceTrans>
          <CustInvoiceTrans class="entity">
            <InventTransId>CCDD</InventTransId>
            <InvoiceId>SI100</InvoiceId>
            <ItemId>555</ItemId>
            <LineAmount>200</LineAmount>
          </CustInvoiceTrans>
          <CustInvoiceTrans class="entity">
            <InventTransId>DDEE</InventTransId>
            <InvoiceId>SI100</InvoiceId>
            <ItemId>555</ItemId>
            <LineAmount>15</LineAmount>
          </CustInvoiceTrans>         
          <CustInvoiceTrans class="entity">
            <InventTransId>EEFF</InventTransId>
            <InvoiceId>SI100</InvoiceId>
            <ItemId>12345</ItemId>
            <LineAmount>40</LineAmount>
          </CustInvoiceTrans>
          <TaxTrans class="entity">
            <InventTransId>AABB</InventTransId>
            <TaxAmount>-21</TaxAmount>
            <TaxBaseAmount>-100</TaxBaseAmount>
            <TaxValue>21.00</TaxValue>
          </TaxTrans>
          <TaxTrans class="entity">
            <InventTransId>BBCC</InventTransId>
            <TaxAmount>-5.25</TaxAmount>
            <TaxBaseAmount>-25</TaxBaseAmount>
            <TaxValue>21.00</TaxValue>
          </TaxTrans>
          <TaxTrans class="entity">
            <InventTransId>CCDD</InventTransId>
            <TaxAmount>-42</TaxAmount>
            <TaxBaseAmount>-200</TaxBaseAmount>
            <TaxValue>21.00</TaxValue>
          </TaxTrans>
          <TaxTrans class="entity">
            <InventTransId>DDEE</InventTransId>
            <TaxAmount>-3.15</TaxAmount>
            <TaxBaseAmount>-15</TaxBaseAmount>
            <TaxValue>15</TaxValue>
          </TaxTrans>
          <TaxTrans class="entity">
            <InventTransId>EEFF</InventTransId>
            <TaxAmount>-8.40</TaxAmount>
            <TaxBaseAmount>-40</TaxBaseAmount>
            <TaxValue>15</TaxValue>
          </TaxTrans>         
</CustInvoiceJour>

必填输出：

<CustInvoiceJour class="entity">
    <CustInvoiceTrans class="entity">
        <InventTransId>AABB</InventTransId>
        <InvoiceId>SI100</InvoiceId>
        <ItemId>444</ItemId>
        <LineAmount>125</LineAmount>
    </CustInvoiceTrans>
    <CustInvoiceTrans class="entity">
        <InventTransId>CCDD</InventTransId>
        <InvoiceId>SI100</InvoiceId>
        <ItemId>555</ItemId>
        <LineAmount>215</LineAmount>
    </CustInvoiceTrans>
    <CustInvoiceTrans class="entity">
        <InventTransId>EEFF</InventTransId>
        <InvoiceId>SI100</InvoiceId>
        <ItemId>12345</ItemId>
        <LineAmount>40</LineAmount>
    </CustInvoiceTrans>
    <TaxTrans class="entity">
        <InventTransId>AABB</InventTransId>
        <TaxAmount>-26.25</TaxAmount>
        <TaxBaseAmount>-125</TaxBaseAmount>
        <TaxValue>21.00</TaxValue>
    </TaxTrans>
    <TaxTrans class="entity">
        <InventTransId>CCDD</InventTransId>
        <TaxAmount>-45.15</TaxAmount>
        <TaxBaseAmount>-215</TaxBaseAmount>
        <TaxValue>21.00</TaxValue>
    </TaxTrans>
    <TaxTrans class="entity">
        <InventTransId>EEFF</InventTransId>
        <TaxAmount>-8.40</TaxAmount>
        <TaxBaseAmount>-40</TaxBaseAmount>
        <TaxValue>15</TaxValue>
    </TaxTrans>       
</CustInvoiceJour>

我不知道这是否有可能。更alone论从哪里开始？

您可以将CustInvoiceTrans元素进行两次分组，一次是对它们的成分进行分组和汇总，第二次是创建引用的TaxTrans元素的总和，而您只需使用键{{1} };下面显示了如何创建分组的<xsl:key name="RefTaxTrans" match="TaxTrans" use="InventTransId"/>并计算TaxTrans的总和，您只需要复制其他元素，分别将模板中的其他元素与TaxAmount结果元素相加：

TaxTrans

然后可以在默认模式下，在<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="xml" indent="yes" /> <xsl:key name="CustInvoiceTrans" match="CustInvoiceTrans" use="ItemId"/> <xsl:key name="RefTaxTrans" match="TaxTrans" use="InventTransId"/> <xsl:template match="@* | node()"> <xsl:copy> <xsl:apply-templates select="@* | node()"/> </xsl:copy> </xsl:template> <xsl:template match="CustInvoiceJour"> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:apply-templates select="CustInvoiceTrans[generate-id() = generate-id(key('CustInvoiceTrans', ItemId)[1])]" mode="tax"/> </xsl:copy> </xsl:template> <xsl:template match="CustInvoiceTrans" mode="tax"> <TaxTrans> <xsl:variable name="referenced-tax" select="key('RefTaxTrans', key('CustInvoiceTrans', ItemId)/InventTransId)"/> <TaxAmount> <xsl:value-of select="sum($referenced-tax/TaxAmount)"/> </TaxAmount> </TaxTrans> </xsl:template> </xsl:stylesheet>行之前，使用另一个apply-templates为CustInvoiceTrans元素添加常规分组。或者，可能更容易存储每个组的第一项，然后两次应用模板，一次是在默认的未命名模式下，第二次是在所引用项的模式下：

<xsl:apply-templates select="CustInvoiceTrans[generate-id() = generate-id(key('CustInvoiceTrans', ItemId)[1])]" mode="tax"/>
