Not Twig but Simple: 

use strict;
use warnings;
use XML::Simple;

my $xml = XMLin( 'CC.xml' );
for (@{ $xml->{Week}{Day} }) {
  print $_->{Times}{Time}{'start-time'},"\n" if $_->{'day-of-week'} eq
+ "Tuesday";
}

  • 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.
