Inverting Template::Toolkit

talexb has asked for the wisdom of the Perl Monks concerning the following question:

I'm in a situation where I'd like to be able to use a Template::Toolkit file (the template, with variables where the data will go) and a populated file and go backwards to get a hash of variables that contain the corresponding values.

That is, if I have a template

directory: [%- foobar -%]
and a config file
directory: /home/alpha/beta
then eventually I'll have
$variables{'foobar'} = '/home/alpha/beta';

Hmmm .. I do have conditionals in my file, so this may be a tough nut to crack .. let me tinker a bit. But if you have ideas, feel free!

      From the CPAN notes:

        This document describes version 0.39 of Template::Extract, released July 15, 2005.

      Wow.

      That's fresh software. Thanks! I'll try it out.

      Wow that's impressive. If you'd combine the generate and extract modules, you could get the data from a template-driven site.
