需要统计以下 XML 在所有子层级中父节点的子节点和大子节点的数量。

如何查找，<regPackagingHierarchyList> 下的孩子数节点为<recordId>

我尝试了以下代码

<xsl:for-each select="LSRIMSData/agl_result/RegistrationPackaging/regPackagingHierarchyList/RegistrationPackagingHierarchy[recordId/text()!='']">
    <xsl:value-of select="count(child::regParentPackagingHierarchy/RegistrationPackagingHierarchy/recordId/node())"></xsl:value-of>
</xsl:for-each>

                  </RegistrationPackagingHierarchy>

        </regPackagingHierarchyList>
      </RegistrationPackaging>
    </agl_result>
  </LSRIMSData>
</agConnectXML>

预期结果将采用以下格式

计数（regParentPackagingHierarchy/RegistrationPackagingHierarchy/RecordIds） = 1 计数（regParentPackagingHierarchy/RegistrationPackagingHierarchy/RecordIds） = 3

如何查找，<regPackagingHierarchyList> 下的孩子数节点为<recordId>

您的输入中只有一个regPackagingHierarchyList 实例。假设您的意思是RegistrationPackagingHierarchy，并且您实际上想要计算每个RegistrationPackagingHierarchy 的后代（不仅是子代）的所有recordId 元素，您可以尝试以下操作：

<xsl:template match="/agConnectXML">
    <xsl:for-each select="LSRIMSData/agl_result/RegistrationPackaging/regPackagingHierarchyList/RegistrationPackagingHierarchy">
        <xsl:text>count = </xsl:text>
        <xsl:value-of select="count(descendant::recordId)"/>
        <xsl:text>&#10;</xsl:text>
    </xsl:for-each>
</xsl:template>

给定您的 XML 示例，结果将是：

count = 2
count = 4
