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

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! :-))


->[0] is orrible and unthinkable :-)



Perhaps you're confusing array and array refs:

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


I thought they was the same! :-o



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


Thanks for the precious info! I've still a lot to learn about perl.

I love python but perl can still do a lot :-P

I agree. I  perl you can have an array, but [0] return error. If you
cicle on it, you get the results.

You can try it with $eprint->get_value( 'creators' )[0]<- does not work

returning $eprint->get_value( 'creators' ) gives an ARRAY *hex number*

foreach my $c ( @{$creators} )

works.

I don't know why :-)
