All I want to know/do is read in a file and parse it.
The following code will read an input file, parse using Parse::RecDescent, then write the output to a file. I adapted the example code from Parse-RecDescent-FAQ (Super Search is your friend).

The input file consists of just a single line: aa

The output file also consists of just a single line: a 

use strict; 
use warnings; 
use Parse::RecDescent;
use File::Slurp;

my $grammar = 'startrule: ( "a" | "aa" ) "a"';
my $parser  = Parse::RecDescent->new($grammar);

my $text = read_file('input.txt');
write_file('output.txt', $parser->startrule($text), "\n");

Hopefully, you can apply this trivial example to your code. (Keep in mind that this is the 1st time I've ever used Parse::RecDescent.)
