Yes, the "." means "anything" in regex language... Btw, you probably want to filter on the mimetype rather than the extension. And if you really want to filter on the extension, I'd rather recommend something like FILTER(fn:ends-with(nie:url(?video), ".rm")). Cheers Adrien

SELECT nie:url(?u) WHERE { ?u a nmm:MusicPiece FILTER regex( nie:url(?u),\"Bobby\") If you use rmvb instead of Bobby, you can get files containg "rmvb" word.
