[英]Convert XML file to CSV with total record count and combining few columns
我们需要将 XML 文件转换为 csv，并在预告片中添加总记录数，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，但找不到将几列合并为一列的方法。 我是 XSLT 的新手，真的希望有人能帮助我。
请在下面的示例中找到更多详细信息。
输入 xml 文件

预计 output

T~2
在哪里
Internal_Description 是列的组合：Internal_Description1、Internal_Description2、Internal_Description3、Internal_Description4、Internal_Description5
描述列是以下各项的组合：Description1、Description2、Description3、Description4、Description5
下面是我用于转换但没有找到组合列的方法的 XSLT 代码。

鉴于您使用 XSLT 2.0，请考虑for-each-group ，其中您 map 遍历所有@name值，而没有标题的后缀数字，并再次用于字符串连接所有组值的记录：
