Or do you mean all files in a tree with 0 bytes? And then there is the question of whether hidden files (.something) should be included in the search. The unix way is the tersest (this example includes hidden files) 
find /whatever/path/ -size 0 -exec rm {} \;

And the perl way, with hidden files filtered out this time: 
Purge( '/whatever/path' );
sub Purge {
    my $dir = shift;
    open my $dh or die "$!, for $dir";
    for my $file ( grep !/^\./, readdir $dh ) {
        my $path = "$dir/$file";
        if ( -d $path ) {
            Purge( $path );
        }
        else {
            ( -z $path ) and unlink $path;
        }
    }
    close $dh or die "$!, for $dir";
}
