Sorry, not sure what would follow "hello" as I'm not Australian and English is not my native language.
Would it be acceptable to have the script written in PHP, reading a CSV file (or excel sheet, but no point adding complexity if CSV would work)? It can be run just like Python code, from command line, without having to install anything.
If OK with you, such a script can probably be done within a couple of hours (can't be more exact without all the xml generation details)
