[EP-tech] Re: Random question: Eprint core fields

[Sebastien Francois]

Yuri,

This will work:

print $eprint->get_value( 'creators' )->[0];

Or:

print $eprint->get_value( 'creators' )->[0]->{name}->{given};

(but that's not very pretty! :-))

Perhaps you're confusing array and array refs:

my @array = ( 'hello', 'world' );
my $arrayref = [ 'hello', 'world' ];

# both prints 'hello':
print $array[0];
print $arrayref->[0];

Seb.
