Module Discussion:Bio::SearchIO::blastxml

Using a recent SVN co of bioperl-live (revision 14980), I am trying to count the number of results with:

my $parser =
  new Bio::SearchIO( -format => 'blastxml',
		     -file   => 'my.blast.out.xml' );
 
warn "parsed (", $parser->result_count(), ")\n";

However, I get the following error:

------------- EXCEPTION: Bio::Root::NotImplemented -------------
MSG: Abstract method "Bio::SearchIO::result_count" is not implemented by package Bio::SearchIO::blastxml.
This is not your fault - author of Bio::SearchIO::blastxml should be blamed!

STACK: Error::throw

STACK: Bio::SearchIO::result_count /homes/dbolser/perl5/lib/perl5/Bio/SearchIO.pm:410
STACK: ./visualizeBlastHitsToChr.plx:34
----------------------------------------------------------------

This is annoying, because when I use the -m8 format of the same blast result I get:

Use of uninitialized value in warn at ./visualizeBlastHitsToChr.plx line 34, <DATA> line 192.
parsed ()

Is this a bug or am I doing something wrong? The blasttable looks like this:
