如何在 XSLT 中从 XML 中的递归内部节点获取数据

Question

我正在尝试获取具有相同名称数据的内部递归节点。 下面是我的示例 XML，我需要以格式输出

**

RegistrationIncludedProduct-43756.regPackagingHierarchyList-43767.regChildPackagingHierarchyList-43765.regChildPackagingHierarchyList-43763.regChildPackagingHierarchyList-43760

我尝试使用您给定的代码重现您的输出。这会产生您想要的输出：

<xsl:template match="regIncludedProduct">
    <fo:block>
        <xsl:call-template name="getContext"/> <!-- This is the first text in the numbering so we do not need the preceding '.' -->
        <xsl:text>-</xsl:text>
        <xsl:value-of select="RegistrationIncludedProduct/recordId"/>
        <xsl:apply-templates select="following-sibling::regPackagingHierarchyList[1]//recordId"/> 
        <!-- Based on your xml you can choose beween following:: and following-sibling:: , there is also the possibility to not only take the first following occurence. If you want to archive this just delete the [1] -->
    </fo:block>
</xsl:template>

<xsl:template match="recordId">
    <xsl:text>.</xsl:text>
    <xsl:call-template name="getContext"/>
    <xsl:text>-</xsl:text>
    <xsl:value-of select="."/> <!-- '.' takes the text of the current context/node you are in, which is recordId -->
</xsl:template>

<xsl:template name="getContext">
    <xsl:choose>
        <xsl:when test="self::regIncludedProduct">RegistrationIncludedProduct</xsl:when>
        <xsl:when test="ancestor::regParentPackagingHierarchy">regChildPackagingHierarchyList</xsl:when>
        <xsl:when test="ancestor::regPackagingHierarchyList">regPackagingHierarchyList</xsl:when>
    </xsl:choose>
</xsl:template>

<xsl:template match="/">
    <xsl:apply-templates select="//regIncludedProduct"/>
</xsl:template>

如果您有任何问题，请随时提出。 :)

According to @Christian Mosz
Try:-
  <xsl:template match="@*|node()">
  <xsl:apply-templates/>
  </xsl:template>

  <xsl:template match="regPackagingHierarchyList">
  <xsl:value-of select="//following::regPackagingHierarchyList[1]//recordId"/>
  </xsl:template>
