Hello All,
I posted the following on PerlMonks but have not found a solution.
Could someone please comment on solutions to the following error. I am
using the Library of Congress driver to look up book info based on
ISBN
numbers. I am not clear on how to combine the driver pm file with the
script, etc. I have also tested several other Driver files.
use WWW::Scraper::ISBN::Driver;
use WWW::Scraper::ISBN::LOC_Driver;
$driver = WWW::Scraper::ISBN::LOC_Driver->new();
$driver->search("0764516965");
$driver->verbosity(1);
my $book = $driver->book();
print $book('title');
That line should be:
print $book->{title};
You should also be checking to see whether the search was successful.
print $driver->error;
and here is the result :
Can't use an undefined value as a symbol reference at isbn_lookup2.pl
+line 9. {the 'title' line}
