The Template Toolkit can use callbacks. I'm not sure exactly what you want to do, but this demonstrates the general idea. 
#!/usr/bin/perl                                                       
+                         

use strict;
use warnings;
use Template;                                                         
+                       

my $tt = Template->new;                                               
+                                 

my $data = { word => 'callbacks',
             emphasise => \&emphasise };
                                                                      
+          
$tt->process(\*DATA, $data) || die $tt->error(), "\n";
                                                                      
+          
sub emphasise {
  return "** @_ **";
}
                                                                      
+          
__DATA__
This is a template.
It includes [% emphasise(word) %]
