将XML文件转换为CSV，记录总数和合并的几列

我们需要将XML文件转换为csv，并在尾部添加总记录计数，并将XML文件中的一些列添加到一列中。
通过使用XSLT，我能够在Trailer记录中实现总行数，但没有找到将几列合并为一列的方法。我是XSLT新手，真的希望有人能帮助我。
请查看以下示例以了解更多详细信息。
输入xml文件

其中

  • Internal_Description是列的组合：内部描述1、内部描述2、内部描述3、内部描述4、内部描述5
  • 说明列是以下内容的组合：描述1、描述2、描述3、描述4、描述5

下面是我用于转换的XSLT代码，但没有找到组合列的方法。

如果使用XSLT 2.0，请考虑for-each-group，其中Map了所有@name值，但没有标头的后缀号，并再次Map了记录，其中字符串连接了所有组值：
