我想在每个 order_h 下从 order_h 匹配 order_no 追加多个子节点 order_d。

这是我的xml

这需要我当前使用的 xslt，它是从我之前的帖子中获得的

有人可以让我知道如何获得预期的输出。@Dimitre 很抱歉没有在我之前的帖子中解释我的确切要求。

提前致谢。

如果您使用的是 XSLT1.0，那么这是一项称为 Muenchian Grouping 的技术的工作。您正在按order_no属性对order_h元素进行分组，在这种情况下，您定义以下键：

 <xsl:key name="order" match="order_h" use="@order_no" />

接下来，对于每个order_h元素，您需要将组中首先出现的元素与其给定的order_no属性相匹配。您可以按如下方式执行此操作：

<xsl:template match="order_h[generate-id() = generate-id(key('order', @order_no)[1])]">

为了解释这是如何工作的，表达式key('order', @order_no)[1]返回当前属性的键中的第一个元素。然后将其与当前元素进行比较以查看它是否匹配。

在此模板中，您可以复制元素，并像这样输出所有子元素

<xsl:apply-templates select="key('order', @order_no)/*" />

您还需要一个模板来匹配其他order_h元素，以便它们不会输出两次：

<xsl:template match="order_h" />

这是完整的 XSLT

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

   <xsl:key name="order" match="order_h" use="@order_no" />

   <xsl:template match="order_h[generate-id() = generate-id(key('order', @order_no)[1])]">
      <order_h>
         <xsl:apply-templates select="@*"/>
         <xsl:apply-templates select="key('order', @order_no)/*" />
      </order_h>
   </xsl:template>

   <xsl:template match="order_h" />

   <xsl:template match="@*|node()">
      <xsl:copy>
         <xsl:apply-templates select="@*|node()"/>
      </xsl:copy>
   </xsl:template>
</xsl:stylesheet>

这应该有望为您提供所需的输出。

如果您使用的是 XSLT2.0，则可以使用xsl:for-each-group来实现相同的目的

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
   <xsl:output method="xml" indent="yes"/>

   <xsl:template match="order">
      <order>
         <xsl:for-each-group select="order_h" group-by="@order_no">
            <order_h>
               <xsl:apply-templates select="@*"/>
