Ok, I've been trying to break things down with the info you have provided, intially with a simpler problem so I can work out whats going on. I'm trying to print the year from the title in a file called csv3 (which contains 1989 in the title) using the following code but it isn't printing anything, what am I doing wrong?
#!/bin/perl
open CSV3, "<csv3" or die;
while (<CSV3>) {
chomp;
my ($title) = $_ =~ /^.+?,\s*([^,]+?),/; #/ match the title
my %words;
$words{$_}++ for split /\s+/, $title; #/ get words
## Collect unique words
#+
# my @titlewords = keys(%words);
+
my @titlewords = keys(%words);
#print "$title"
}
sub find_year {
my( $str ) = @_;
my $year;
$year = $1
if( $str =~ /\b((?:19|20)\d\d)\b/ );
return $year
}
&find_year ($title);
I would have thought the
&find_year ($title); would have taken the title and applied the subroutine to this string, picking out the 1989?
