Welcome to the Monastery, and please read Writeup Formatting Tips.

If I correctly deciphered your XML, then you are probably looking for something like: 

use strict;
use warnings;

my $xml = <<XML;
<?xml version="1.0" encoding="utf-8"?>
<root>
  <class name="music">
    <record type="month" index="0">
      <string>sam1</string>
      <string>sam2</string>
    </record>
    <record type="month" index="1">
      <string>mike1</string>
      <string>mike2</string>
    </record>
  </class>
  <class name="english">
    <record type="week" index="2">
      <string>luke1</string>
      <string>luke2</string>
    </record>
    <record type="month" index="3">
      <string>ben1</string>
      <string>ben2</string>
    </record>
  </class>
</root>
XML

use XML::Twig;
my $t = XML::Twig->new(twig_handlers => {class => \&class});
$t->parse($xml);

sub class {
    my ($twig, $cl) = @_;
    print "class name = ", $cl->att('name'), "\n";
    for my $rec ($cl->children('record')) {
        print "type = ", $rec->att('type');
        print ", index = ", $rec->att('index'), "\n";
    }
}

__END__

class name = music
type = month, index = 0
type = month, index = 1
class name = english
type = week, index = 2
type = month, index = 3

Title:

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • 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.
  • Please read these before you post! —
