Thank you!

It seem's not to work in my case. Here's the code which actually imitates
some part of the 'sitemap'. It tries to find all contents which refer to 
the current on as 'up'. Now I'm trying to solve the problem by better
understanding how to use the alredy built sitemap :-).

---------------------------------- snip ------------------------------------
<template name=all_sub_sections>
<{perl

        my $curname = get_current_main_content();

        $_ = "|";
        foreach my $pg (content_matching ("*.txt")) {

          my $pg2 = get_content_object($pg);
          $pg =~ s/.txt//;

          my $title = $pg2->get_title();

          my $myup  = '${'.$pg2->{name}.'.up}';
#         my $myup  = $pg2->{main}->quiet_curly_meta_subst
#                                 ($HTML::WebMake::Main::SUBST_META,
#                                 $pg2->{name}.".up");

          if ( $myup =~ $curname ) {
                  $_ .= "<a href=\$($pg)> $title </a> | ";
          }
        }
        $_;
}>
</template>

I think I'm missing the deep insight in the internals of WebMake to understand
that. But maybe I'll find out :-).
