Re: Splitting multiple patterns

[stevieb]

You could split the line the first time at the space, assigning the name as the first side of the whitespace and put the rest into another variable, then split the $rest variable on the commas:

#!/usr/bin/perl

use warnings;
use strict;

open my $fh, "<", "infos.txt" or die "cannot open infos.txt: $!";

while ( my $line = <$fh> ){
    chomp $line;

    my ( $name, $rest ) = split /\s+/, $line;

    my ( $age, $gender, $address ) = split /,/, $rest;

    print "Name:    $name\n";
    print "Age:     $age\n";
    print "Gender:  $gender\n";
    print "Address: $address\n";
    print "\n";
}

Output:

Name:    Mawts
Age:     25
Gender:  female
Address: melbourne

Name:    Awts
Age:     24
Gender:  male
Address: sydney

Hi stevieb

How about if I put the infos.txt file into a array first and then splitting it from there. like first it will open the .txt file then putting it in a array, then split them inside..

open(INFILE, "<", "infos.txt") or die ("cannot open input: $!");
my @infos = <INFILE>;
chomp(@infos);

How can I split the datas on my @infos? thanks

It's really not much different. However, slurping in the whole file can run you out of memory if your file is very large.

#!/usr/bin/perl

use warnings;
use strict;

open my $fh, "<", "infos.txt" or die "cannot open infos.txt: $!";

my @array = <$fh>;

close $fh;

for my $line ( @array ){

    chomp $line;

    my ( $name, $rest ) = split /\s+/, $line;

    my ( $age, $gender, $address ) = split /,/, $rest;

    print "Name:    $name\n";
    print "Age:     $age\n";
    print "Gender:  $gender\n";
    print "Address: $address\n";
    print "\n";
}

Hi stevieb,

One last question. How about if want to get only the $address? and only print the "Address:"? What I want is to split the Name up to Gender so that it will only read the $address

Thanks
