Since default XML importer requires a very specific XML format, to ease my pain while working with Kenney’s spritesheets, I’ve quickly wrote my own importer for Content Pipeline, which I’d like to share in hope it helps anyone else.
I’ve also commited a built DLL so there’s no need for downloading whole solution. It’s located as usual (/bin/Release).
