in reply to REGEX: muliple search and replace

While I am well-known as a fan of regexes, I wouldn't recommend them here. Since you're already using a template, why not go whole hog and take advantage of the features of HTML::Template? Take the following template: 
<HTML>
<HEAD><TITLE>Test Template</TITLE>
<BODY>
<H1><TMPL_VAR NAME=something></h1>
<!--<TMPL_VAR NAME=var1>-->
This is a lame Web page
<!--<TMPL_VAR NAME=var2>-->
</BODY>
</HTML>

Use the following CGI script: 
#!c:\perl\bin\perl.exe -wT
use strict;
use HTML::Template;
use CGI qw/:standard/;

# open the html template
my $template = HTML::Template->new(filename => 'template.tmpl');

# fill in some parameters
$template->param(
    something => "Test",    
    var1      => "Some Comment",
    var2      => "Another comment"
);

print header,
      $template->output;

You'll see that the HTML comments have been filled in quite nicely. Read the documentation of this module and you'll see how very useful it can be.
