Pretty much straight from the documentation, for example.
#!/usr/bin/perl
use strict;
use warnings;
use Text::CSV_XS;
my $csv = Text::CSV_XS->new ({ binary => 1, eol => $/ });
my $file = 'o33.txt';
open my $io, "<", $file or die "$file: $!";
my $header = $csv->getline ($io);
print join("-", @$header), "\n\n";
while (my $row = $csv->getline ($io)) {
print join("-", @$row), "\n";
}
__END__
***contents of o33.txt
lastname,firstname,age,gender,phone
mcgee,bobby,27,M,555-555-5555
kincaid,marl,67,M,555-666-6666
hofhazards,duke,22,M,555-696-6969
Prints:
lastname-firstname-age-gender-phone
mcgee-bobby-27-M-555-555-5555
kincaid-marl-67-M-555-666-6666
hofhazards-duke-22-M-555-696-6969
Update: Thinking about your problem, it may be that you want to address the data by its column name. For that, you might be able to use something (also from the docs), like this:
$csv->column_names ($csv->getline ($io));
while (my $href = $csv->getline_hr ($io)) {
print "lastname is: ", $href->{lastname},
" and gender is: ", $href->{gender}, "\n"
}
Note: You can use Text::CSV
instead of Text::CSV_XS
, as the former is a wrapper around the latter.
