Hello all,

I have question about using DBIx::Tree::NestedSet and using it. My aim is very easy, I have some categories and I'd like to store them in DB as tree. I found this nice module, I like it, but I run into problems and I don't know what to do further.
here is snippet what I wrote: 
use strict;
use warnings;
use DBIx::Tree::NestedSet;
use DBI;

my $dbh = DBI->connect('DBI:mysql:test','root','')
                       or die ($DBI::errstr);
my $tree = DBIx::Tree::NestedSet->new( dbh => $dbh,
                                       no_locking => 1,
                                       table_name => 'db_tree'
);
$dbh->do("DELETE from db_tree");

#we can't have more "top" categories, so we create "main"
$tree->add_child_to_right( name=>'main' );

while (<DATA>) {
        chomp;
        my $hr;
        for my $item ( split '/' ) {
                $hr->{last_id} = $tree->add_child_to_right(
                        name => $item, 
                        id => $hr->{last_id}
                );
        }

}

print "\nThe Complete Tree:\n";
print $tree->create_report();

__DATA__
foo/bar
bar/foo
foo/bar/foo

Output is: 
The Complete Tree:
main (354)(1)
  foo (355)(2)
    bar (356)(3)
  bar (357)(2)
    foo (358)(3)
  foo (359)(2)
    bar (360)(3)
      foo (361)(4)

Ok, now problem - I don't want to have "foo/bar" and "foo/bar/foo" as separate paths, but instead only one: "foo/bar/foo" could anyone help me please ?
