Question

我想比较输入xml中两个不同元素的数量，如果数量匹配，则将“Y”分配给xsl中的变量。

如果 ReceiptLine 元素Quantity和 OrderLine OrderedQuantity匹配相同的PrimeLineNo属性。我认为xsl应该有两个for-each循环和一个带有Y或N值的变量 completeShipment 。

这是输入XML。

<?xml version="1.0"?> <Receipt DocumentType="0005" ReceivingNode="110"> <Shipment DocumentType="0005" EnterpriseCode="CostcoUSA" OrderNo="Y100000594" ReceivingNode="110"/> <ReceiptLines> <ReceiptLine PrimeLineNo="1" SubLineNo="" OrderNo="Y100000600" Quantity="40.00"/> <ReceiptLine PrimeLineNo="2" SubLineNo="" OrderNo="Y100000600" Quantity="30.00"/> </ReceiptLines> <OrderDetails> <Order OrderHeaderKey="201402041210274226042" OrderNo="Y100000594" EnterpriseCode="CostcoUSA" DocumentType="0005"> <OrderLines> <OrderLine OrderedQuantity="40" PrimeLineNo="1" SubLineNo="1" > <OrderLine OrderedQuantity="30" PrimeLineNo="2" SubLineNo="2" > <ChainedFromOrderLine> <Order> <Extn ExtnSpecialHandlingFlagt="N" /> </Order> </ChainedFromOrderLine> </OrderLine> </OrderLine> </OrderLines> </Order> </OrderDetails> </Receipt>

这是输出xml

<?xml version="1.0"?> <Receipt DocumentType="0005" ReceivingNode="110"> <Shipment DocumentType="0005" EnterpriseCode="CostcoUSA" OrderNo="Y100000594" ReceivingNode="110"/> <ReceiptLines> <ReceiptLine PrimeLineNo="1" SubLineNo="" OrderNo="Y100000600" Quantity="40.00"/> <ReceiptLine PrimeLineNo="2" SubLineNo="" OrderNo="Y100000600" Quantity="30.00"/> </ReceiptLines> <OrderDetails> <Order OrderHeaderKey="201402041210274226042" OrderNo="Y100000594" EnterpriseCode="CostcoUSA" DocumentType="0005"> <OrderLines> <OrderLine OrderedQuantity="40" PrimeLineNo="1" SubLineNo="1" > <OrderLine OrderedQuantity="30" PrimeLineNo="2" SubLineNo="2" > <ChainedFromOrderLine> <Order> <Extn ExtnSpecialHandlingFlagt="N" /> </Order> </ChainedFromOrderLine> </OrderLine> </OrderLine> </OrderLines> </Order> </OrderDetails> <ExtnXSL ExtnXSLSpecialHandlingFlag="N" ExtnXSLCompleteShipment="Y" /> </Receipt>

以下是我需要帮助的ExtnXSL的xsd：

<ExtnXSL> <xsl:variable name="completeShipment"> <xsl:for-each select="Receipt/ReceiptLines/ReceiptLine"> <xsl:variable name="receiptQty" select="@Quantity"/> <xsl:varaible name="rPrimeLineNo" select="@PrimeLineNo"/> <xsl:for-each select="//Receipt/OrderDetails/Order/OrderLines/OrderLine[PrimeLineNo=rPrimeLineNo]"> <xsl:varaible name="orderedQty" select="@OrderedQuantity"/> <xsl:if test="orderedQty != receiptQty"> <xsl:value-of select="'N'"/> </xsl:if> </xsl:for-each> </xsl:for-each> <xsl:if test="completeShipment != 'N'"> <xsl:variable name="completeShipment" select="'Y'"/> </xsl:if> <xsl:attribute name="ExtnXSLSpecialHandlingFlag"> <xsl:value-of select="'N'"/> </xsl:attribute> <xsl:attribute name="ExtnXSLCompleteShipment"> <xsl:value-of select="$completeShipment"/> </xsl:attribute> </ExtnXSL>

如果ReceiptLine元素Quantity和OrderLine OrderedQuantity 匹配相同的PrimeLineNo属性

在您的示例中，对于ReceiptLine，PrimeLineNo属性为空，对于OrderLine，PrimeLineNo属性为“1”，因此不匹配。您是否想过按OrderNo匹配数量？使用键可以很容易地做到这一点。例如，应用以下样式表：

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:key name="receipt" match="ReceiptLine" use="@OrderNo" />

<xsl:template match="/">
    <output>
        <xsl:for-each select="Receipt/OrderDetails/Order">
            <Order>
                <xsl:copy-of select="@OrderNo"/>
                <OrderedQuantity>
                    <xsl:value-of select="sum(OrderLines/OrderLine/@OrderedQuantity)"/>
                </OrderedQuantity>
                <ReceivedQuantity>
                    <xsl:value-of select="sum(key('receipt', @OrderNo)/@Quantity)"/>
                </ReceivedQuantity>
            </Order>
        </xsl:for-each>
    </output>
</xsl:template>

</xsl:stylesheet>

到您的示例输入将导致：

<?xml version="1.0" encoding="UTF-8"?>
<output>
   <Order OrderNo="Y100000123">
      <OrderedQuantity>50</OrderedQuantity>
      <ReceivedQuantity>50</ReceivedQuantity>
   </Order>
</output>

比较嵌套for-each循环Xslt中的数量
