我尽力使用下面的命令找出xmlstarlet的错误。不过，我无法让它毫无错误地运行。
命令：
xmlstarlet edit \
--update "//job/input/file_input/uri" \
--value 's3://my_source' \
--update "//job/output_group/file_group_settings/destination/uri" \
--value 's3://my_destination' \
--append "//job/input/file_input/uri" \
--type elem --name "audio" --value "track_01" template.xml > new_file.xml
这是我的模板XML。

我使用diffchecker.com比较两个xmls。
<user_data>和<name_modifier>的开放元素缺失。
任何帮助都非常有价值。
非常感谢
