Argh. I can't remember where, but I ran across a Website package using HTML::Template that had this feature.
Aha! Found it!
Yapcom, the CGI::App-based application to handle registration and workshops for YAP conferences!
Here is the relevant piece of code. Personally, I think this is a VERY tasty hack. It lets page designers plug parameters back into the templating system for use elsewhere. Very cool.
sub _server_page {
my $self = shift;
my ($page) = @_;
my $q = $self->query;# we allow tags like this in our templates that will define values
# to be set as parameters
# <TMPL_VALUE NAME="name" VALUE="value">
my %h;
my $filter = sub {
my $text_ref = shift;
while ($$text_ref =~ s/<\s*TMPL_VALUE\s+NAME="([^"]*)"\s+VALUE="([^"]*)"\s*>//) {
$h{$1} = $2;
}
};
my $t = $self->load_tmpl(
"$page.tmpl",
die_on_bad_params => 0,
filter => $filter,
associate => $q,
path => $templates_dir,
); $t->param(%h);
$t->param(VERSION => $YAPC::Organizer::VERSION);return $t; }

The templates in the package have <TMPL_VALUE name="foo" value="bar"> tags and used a filter function to extract them from the templates and insert them into the template params. It was a very neat hack.
