Hi.
Nobody else has mentioned this, but I think it's nice to have a name
to write to. '[EMAIL PROTECTED]' and 'rkl' don't do a lot for me!

Unless there's a good reason not to, I would use an HTML comment tag
<!-- fname -->
<!-- lname -->
etc. so that the HTML parses OK before the subtitutions are done.

Your substitution is fine, just add a /g to it to change all tags
in the string instead of just the first. Like this
$line =~ s/<!-- fname -->/$fname/g;
Unless you have a good reason to read in the whole file at once,
process it a record at a time. Like this:
use strict;
use warnings;
open IN, 'template.htm' or die $!;
my %values = ( fname => 'Rob', lname => 'Dixon' );
while (<IN>) {
s/<!-- fname -->/$values{fname}/g;
s/<!-- lname -->/$values{lname}/g;
print;
}
close IN;
I hope that helps.
Rob
