Hi,
ok, but without knowing how to interpret that XML file (i.e. TablePress can not determine what the columns and rows are automatically), this is not really possible. Also, as that XML format would be very custom to the provider of that data, this would not really be useful to other users. My suggestion is to look for some other method to convert that XML file to something that TablePress understands (like CSV, JSON, HTML, or XLS/XLSX).
Regards,
Tobias
