All the work is being done in "$vg{$_}++" which ignores
the split() and increments the value associated with the key
in $_. That one of those key/value pairs happens to be correct
is just coincidence.

Delete that line. You can read more about the split()
function in the perl documentation.

I think the problem we are having is why use a solution
which resorts to global variables when lexical variables get
the job done fine?
use strict;
use warnings;
my $baz = 'pre-baz';
my $foo = foo();
print $foo, "\n";
print $baz, "\n";
sub foo {
my $foo = &#x
che will then
process the SSI includes of the .shtml file.
BTW, there is a H::T mailing list made exclusively for
H::T questions.

The same is true of a technical email list. If I choose to
use a technical email list for answers I would first read up on
the etiquette for using that list then I would be able to use
that resource correctly.

BTW, I think indent() could be rewritten. I think these do
the same thing as your indent().
sub indent {
my $indent = shift;
return '' unless defined $indent;
return '' x $indent;
}
# Or:
sub indent {
return '' unless defined $_[0];
u actually get an array of arrays you can try the
Sort::ArrayOfArrays module to sort it.

I'm sure it will work, but I hope I don't have to
