If the simplicity of this JSON string is guaranteed, you can try the following very crude (Module free) JSON to perl converter,
use strict;
use warnings;

(my $datastring=do{local $/=undef; <DATA>}) =~s/:/=>/g;
my $data = eval $datastring;

my %by_name = map { $_->{name} => $_->{id} } @{$data->{'genres'}};
print "The ID for Science Fiction is:", $by_name{"Science Fiction"} , 
+"\n";
__DATA__
<<<YOUR JSON Here...>

[download]
Output: 
The ID for Science Fiction is:878

NOT RECOMMENDED for production code.

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
