我无法理解 XSLT 1.0 Muenchian 分组

Question

我基本上只是尝试按容器 ID 对 DCLDET 段进行分组，因此我可以创建一个额外的标签

<Carton>
    <Container_Id>
    <SKU>
    <Qty_Shipped>
</Carton>

我已经阅读了有关 Muenchian 分组的内容，但我所做的一切似乎都无济于事。我想如果我按容器 ID 在 DCL/DCLDET 段上分组，这就是我需要的吗？但我得到的只是没有结构的输出代码（如果需要，可以 post 这个，但它本质上只是没有标签的文本）。

我的XML是这个-

我已经试过了，但是我迷路了。

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    </xsl:template>

</xsl:stylesheet>

Answer 1

你离得不远了，但是犯了一些小错误....

您的 XPath 表达式遗漏了 DCH。 DCL 是 DCH 的子代，而不是 HEAD
您有两个匹配相同表达式 DSV_DESADV0103/HEAD/DCL/DCLDET 的模板（由于第 1 点，它们不会匹配任何内容）。我认为第一个模板应该只匹配 DSV_DESADV0103/HEAD any 因为否则里面的 xsl:apply-templates select anything
您在表达式中使用了 @container_id，但 container_id 不是属性，而是子节点

试试这个 XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output method="xml" indent="yes" />

    <xsl:key name="containerId" match="DSV_DESADV0103/HEAD/DCH/DCL/DCLDET" use="Container_Id" />

    <xsl:template match="DSV_DESADV0103/HEAD">
        <AllUsers>
            <xsl:apply-templates select="DCH/DCL/DCLDET[generate-id(.)=generate-id(key('containerId',Container_Id)[1])]"/>
        </AllUsers>
    </xsl:template>

    <xsl:template match="DSV_DESADV0103/HEAD/DCH/DCL/DCLDET">
        <Division value="{Container_Id}">
            <xsl:for-each select="key('containerId', Container_Id)">
                <User>
                    <id><xsl:value-of select="Tag_Id" /></id>
                    <name><xsl:value-of select="Qty_Shipped" /></name>
                </User>
            </xsl:for-each>
        </Division>
    </xsl:template>
</xsl:stylesheet>

在 http://xsltfiddle.liberty-development.net/6r5Gh4b

查看实际效果

请注意，您现有输出的原因是因为您之前的模板不匹配任何内容，而是使用了 XSLT 的 built-in templates，并且这些只是在它们找到它们的地方输出文本节点。

另请注意，您可以将第二个模板上的匹配简化为 <xsl:template match="DCLDET">，因为您实际上不需要匹配模式的完整路径。
