每个组订单的每个行项目的 XSLT

Question

我是 XSLT 映射的新手 space，我想就我的转换请教一些专家建议。我有一个平面 XML 文件，我希望按装运编号及其相应的行项目和行项目编号对其进行结构化。任何帮助将不胜感激。

这是我的XML

我希望这是目标 XML

<?xml version="1.0"?>

            </DocketLine>
        </DocketLines>
    </WhsDocket>
</WhsDockets>

但我需要在相同的参考编号下有相应的行项目，并添加一个行项目编号来区分它，但这就是我得到的。

            </DocketLines>
        </WhsDocket>
    </WhsDockets>

这是我创建的 XSLT。

Answer 1

这是一个 "grouping" 问题，在 XSLT 1.0 中，通常使用的技术称为 Muenchian Grouping。

首先你定义一个键来代表组。在您的情况下，您按 SAP_Shipment 元素对 Line_Items 元素进行分组，因此您可以像这样定义一个键：

<xsl:key name="items" match="Line_Items" use="SAP_Shipment" />

然后您 select 键中最先出现的 Line_Items 元素为其给定值 SAP_Shipment。这代表每组的开始

<xsl:for-each select="Line_Items[generate-id() = generate-id(key('items',SAP_Shipment)[1])]">

然后您可以使用键获取组中的所有项目（包括第一个项目）：

<xsl:apply-templates select="key('items',SAP_Shipment)" />

初学者试试这个 XSLT

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

    <xsl:key name="items" match="Line_Items" use="SAP_Shipment" />

    <xsl:template match="Orders">
        <WhsDockets>
            <xsl:for-each select="Line_Items[generate-id() = generate-id(key('items',SAP_Shipment)[1])]">
                <WhsDocket>
                    <Identifier><xsl:value-of select="SAP_Shipment" /></Identifier>
                    <DocketLines>
                        <xsl:apply-templates select="key('items',SAP_Shipment)" />
                    </DocketLines>
                </WhsDocket>
            </xsl:for-each>
        </WhsDockets>
    </xsl:template>

    <xsl:template match="Line_Items">
        <DocketLine>
            <LineNumber><xsl:value-of select="position()" /></LineNumber>
            <Product><xsl:value-of select="Material" /></Product>        
        </DocketLine>
    </xsl:template>
</xsl:stylesheet>

注意：如果您能够使用 XSLT 2.0，那么您可以使用 xsl:for-each-group 结构。参见 http://www.xml.com/lpt/a/1314。
