Polymorphism is your friend - definitely subclass! This
way you can define an output method and just call it on
which ever object you instantiated. You could even set
up a factory object that instantiates the object for you.
Here is a very simple example:
package Factory;
sub create {
my $class = shift;
my $obj = 'Base::' . shift;
return $obj->new();
}
package Base;
sub output {
my $self = shift;
return $self->{thing};
}
package Base::Foo;
use base 'Base';
sub new {
my $class = shift;
my $self = { thing => 'foo' };
return bless $self,$class;
}
package Base::Bar;
use base 'Base';
sub new {
my $class = shift;
my $self = { thing => 'bar' };
return bless $self,$class;
}
package main;
my @things = (
Factory->create('Foo'),
Factory->create('Bar'),
);
print $_->output,$/ for @things;
Just replace Base with Resume and Foo and Bar with XML,
HTML, PDF or whatever. Check out

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).
