I glanced over the xdg-open source and saw that it uses xdg-mime to figure out the type. man xdg-mime revealed a default option to set the application to be used:

xdg-mime default application mimetype(s)
   Ask the desktop environment to make application the default
   application for opening files of type mimetype. An application can
   be made the default for several file types by specifying multiple

   application is the desktop file id of the application and has the
   form vendor-name.desktop application must already be installed in
   the desktop menu before it can be made the default handler. The
   aplication's desktop file must list support for all the MIME types
   that it wishes to be the default handler for.

For more about this, see the relevant man pages.

I am not 100% sure, but I think xdg-open relies on what you set in 'file types' in your DE's configuration. I guess you are on KDE, so open KDE system settings and specify that file type.
