Need help extracting XML from SPB with FSX (I only have MSFS which won't work)

Thank you for your time.

I have a SPB file with a flight plan. Inside the SPB file is a complex XML file with the airport and waypoints all listed.

I cannot extract the XML file because I’m using the MSFS version. If you are using the Steam FSX version, it is possible.

Are you able to extract the file? I can WeTransfer the SPB file!

Please let me know.

Many thanks.
Anthony
