They actually do neither ... they are templating modules and have no responsibility of producing valid HTML - that's up to the HTML coder. As for being overkill, well ... the more you use these tools, the quicker you get at coding with them. You can see an example that i am proud of over at 4Re: How do I extract text from an HTML page? that uses HTML::Template. The template is stored inside DATA - creating a new H::T object that uses the DATA filehandle is a snap:

my $template = HTML::Template->new(filehandle => \*DATA);
For the Template-Toolkit quick and simple scripts, check out Inline::TT, it's slow as hell, but when you combine it with Class::DBI you get some amazing results. I am nearly finished with my C::D mini-tut that will demonstrate using C::D with multiple tables, but here is a snippet just to show you the power of the Class::DBI and Template combo. (and by the way, i learned most of this from How to Avoid Writing Code and the poop-group mailing list)
use strict; use warnings; use DVD::movie; use Inline 'TT'; print DVD(movies => [DVD::movie->retrieve_all]); __DATA__ __TT__ [% BLOCK DVD %] [% FOREACH movie = movies %] <img src="http://dvd.unlocalhost.com/images/[% movie.id %].jpg" ali +gn="right" /> <h2>[% movie.title %]</h2> <ul> <li> Year - [% movie.year %]</li> <li>Added - [% movie.timestamp %]</li> <li>Directors:</li> <ul> [% FOREACH director = movie.directors %] <li>[% director.name %]</li> [% END %] </ul> <li>Writers:</li> <ul> [% FOREACH writer = movie.writers %] <li>[% writer.name %]</li> [% END %] </ul> <li>Genres:</li> <ul> [% FOREACH genre = movie.genres %] <li>[% genre.name %]</li> [% END %] </ul> </ul> <br clear="right" /> [% END %] [% END %]
That's just too easy. ;)

    I don't consider that "easy" and I don't think anyone seeking a quikie tutorial on HTML::Tree would either. You presented no less then 3 advanced topics/modules. I know your good jeffa, but don't confuse the newbies :^)

    My point being, that I think this just muddies the water for a newbie. All great stuff, but some people really only use Perl once and a while....really. They aren't building the next greatest web app. Save this stuff for the right nodes.
      Sounds like someone got a bit upset over someone else trying to help. Shame on you trs80.
