Inspired by the request over at hashes, arrays, and references... oh my (the gist is creating objects from XML), i wanted to create a "real" object - one that has accessor methods instead of relying on the client to access $self's reference directly. I also wanted to be able to specify those methods easily, and more importantly, be able to pass a hash to the constructor and have it assign all of the attributes for me. Enter Class::MethodMaker:

#!/usr/bin/perl -l

package Beatle;
use Class::MethodMaker
   new_hash_init => 'new',
   get_set       => [qw(name instruments)],
;

package main;
use strict;
use warnings;
use XML::Simple;

my $xml = XMLin(\*DATA, KeyAttr => []);

for (@{$xml->{beatle}}) {

   my $beatle = Beatle->new(%$_);

   print $beatle->name, ":";

   print "\t$_" for @{$beatle->instruments};
}


__DATA__
<beatles>
   <beatle name="Paul">
      <instruments>Voice</instruments>
      <instruments>Bass</instruments>
      <instruments>Guitar</instruments>
      <instruments>Piano</instruments>
   </beatle>
   <beatle name="John">
      <instruments>Voice</instruments>
      <instruments>Guitar</instruments>
      <instruments>Rhodes</instruments>
   </beatle>
   <beatle name="George">
      <instruments>Voice</instruments>
      <instruments>Guitar</instruments>
      <instruments>Sitar</instruments>
   </beatle>
   <beatle name="Ringo">
      <instruments>Voice</instruments>
      <instruments>Drums</instruments>
      <instruments>Percussion</instruments>
   </beatle>
</beatles>

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
