( #3333=superdoc: print w/ replies, xml ) Need Help??

That sounds reasonable, but this is part of some slightly different functionality that is designed to work specifically with our current Template Toolkit setup here at work. Data::FormValidator appears nice, but I felt that a small, custom-designed tool that is a drop-in replacement for our code was the way to go. My first chance to use this took a 450 line program and reduced it down to 150 lines. No changes to our templates were required. Further, Data::FormValidator makes no reference to untainting the data.

Don't get me wrong, Data::FormValidator looks great, but it didn't appear to quite be what I need. Subclassing it might have been an option, but it makes internal function calls rather than method calls and that can make subclassing a pain because I would have to reimplement the functions rather than inherit them. The code below demonstrates the problem.

#!/usr/bin/perl -w use strict; use Data::Dumper; package Foo; sub new { my $class = shift; bless {}, $class; } sub foobared { my $self = shift; $self->{foo} = _test( 3 ); } sub _test { shift } package Bar; @Bar::ISA = 'Foo'; sub foobared { my $self = shift; $self->{foo} = $self->_test( 3 ); } package Main; my $o = Foo->new; $o->foobared; print $o->{foo},$/; my $o2 = Bar->new; $o2->foobared; print $o2->{foo};

As you can see, mixing regular functions with methods doesn't work. You can't inherit because you have an extra argument.
