One possibility is to call an external program for each XML stream, like this simplified example:

my $remote_program = '/usr/bin/cat'; # set this from the config or pro
+gram options

for (@output) {      # for each xml stream
    open REMOTE,"|$remote_program" or die "Can't pipe to $remote_progr
+am: $!";
    print REMOTE $_; # pipe stream to $remote_program
    close REMOTE;    # end
}
