in thread HTML::Template, pseudo trees and indention.

Ahh. didn't realize how they had to nest. Here is a slightly updated version that passes W3C validation. I assume/hope that means IE will like it.

#!/usr/bin/perl use strict; use HTML::Template; use Data::Dumper; my $template = " <ul> <TMPL_LOOP tree> <li><TMPL_VAR value> (depth=<TMPL_VAR depth>) <TMPL_UNLESS up></li></TMPL_UNLESS> <TMPL_LOOP up><ul></TMPL_LOOP> <TMPL_LOOP down></ul></li></TMPL_LOOP> </TMPL_LOOP> </ul> "; my $tree = [ { 'value' => 'a', 'depth' => 1 }, { 'value' => 'b', 'depth' => 1 }, { 'value' => 'b1', 'depth' => 2 }, { 'value' => 'b2', 'depth' => 2 }, { 'value' => 'c', 'depth' => 1 }, { 'value' => 'c1', 'depth' => 2 }, { 'value' => 'c1.1', 'depth' => 3 }, { 'value' => 'd', 'depth' => 1 } ]; for my $i (0 .. $#$tree) { if (defined $tree->[$i+1]) { my $diff = $tree->[$i+1]->{depth} - $tree->[$i]->{depth}; if ($diff > 0) { $tree->[$i]->{up} = [({}) x $diff]; } elsif ( $diff < 0 ) { $tree->[$i]->{down} = [({}) x -$diff]; } } } my $html_template = HTML::Template->new( scalarref => \$template, loop_context_vars => 1); $html_template->param('tree' => $tree); print $html_template->output;

[hippo]: :-D
[Eily]: you mean a dll where the SW was written in perl? That sounds unlikely
[muthusathish]: please help me regarding this
[hippo]: Easier just to go and look at the source, no?
[Eily]: mostly because perl isn't compiled in the usual sense of the meaning, you can't execute the opcodes directly, you need the perl engine
[muthusathish]: i dont have the environment too, but i need to get the logics so that i can re-wite
[Eily]: what makes you think your dll is "perl based" ?
[muthusathish]: i dont have source code too
[muthusathish]: it is used in VB 6 appln, while debugging is getting error
[hippo]: Somebody has. Ask the author.
