[Bioperl-l] Re: Bio::Biblio to access pubmed?

[Siddhartha Basu]

Hi,
As an alternate I also use Bio::DB::EUtilities frequently query and extract data from pubmed.
Currently it returns xml which needed to be parsed to get specific
information. Here is a small example using xpath query....


#!/usr/bin/perl -w

use strict;
use Bio::DB::EUtilities;
use XML::Twig::XPath;

my $pubmed_id = $ARGV[0] || '18835579';

my $eutils = Bio::DB::EUtilities->new(
    eutil => 'efetch',
    -db   => 'pubmed',
    -id   => $pubmed_id
);

if ( $eutils->get_Response->is_error() ) {
    die $eutils->get_Response->message(), "\n";
}


my $twig = XML::Twig::XPath->new->parse($eutils->get_Response->content());
my ($title) = $twig->findnodes('//Article/ArticleTitle');
print $title->getValue,"\n";

my @authors = $twig->findnodes('//Article/AuthorList/Author');
print $_->getValue,"\n" foreach @authors;
