[Bioperl-l] pubmed

[Brian Osborne]

Qunfeng,

Only 1 of the 5 references in the 56961711 entry has a Pubmed id, the rest
will return nothing when you try $value->pubmed.

so, I tried to use
                     my $authors = $hash_ref->{'authors'};
                     my $medline = $hash_ref->{'medline'};
                     my $pubmed = $hash_ref->{'pubmed'};

to parse out authors, medline, pubmed.

I was able to successfully parse out authors and medline but not pubmed.

Then I tried to use

                     my $authors = $value->authors();
                     my $medline = $value->medline();
                     my $pubmed = $value->pubmed();

and I got the same thing.
