I'm creating a process which will regenerate a configuration file each time it is run. If a certain variable is found in the original config file, I want to avoid clobbering the entry while I'm regenerating the config file.Here's what the config file looks like:

<users>
    <00149>
        <devsrv1>
            lastLogin   Never logged in
            approvedBy  SLS
        </devsrv1>
        <devsrv2>
            lastLogin   Never logged in
        </devsrv2>
    </00149>
</users>

This would be what the original config file would look like. Let's say I'm ready to regenerate the config file. While parsing throught the above, I want to ignore all records which contain the variable, "approvedBy", when I'm regenerating the config file.

Here's the code that I've got, so far:

## assume that I'm using strict, using warnings, and that all data str
+uctures tus far, are populated correctly. I'm truncating the code for
+ the sake of brevity

    foreach my $inner (keys %{$users{$lastuid}})
    {

        my $last = $users{$lastuid}{$inner};
        genCtl($inner, $last, $lastuid);
    }

   print FH "\t\<\/m$newuid\>\n";

}

print FH "\<\/users\>\n";

$conn->close;
close FH;

my $conf =
  new Config::General(
                      -ConfigPath      => \@path,
                      -ConfigFile      => "$ctlFile",
                      -ExtendedAccess  => 1,
                      -InterPolateVars => 1
                     );

my %config = $conf->getall();
$conf->save_file("$tmpctlFile");

&procCtl;


sub genCtl
{
    my ($server, $last, $uid) = @_;

    print FH "\t\<$server\>\n";
    print FH "\t\tlastLogin $last\n";
    print FH "\t\<\/$server\>\n";

    print FH "\t\tlastLogin $last\n";
    print FH "\t\<\/$server\>\n";
}

sub procCtl

{

my $tmpCtl =
  new Config::General(
                      -ConfigPath      => \@path,
                      -ConfigFile      => "$tmpctlFile",
                      -ExtendedAccess  => 1,
                      -InterPolateVars => 1
                     );

my %tmpCtl = $tmpCtl->getall();

my $goldCtl =
  new Config::General(
                      -ConfigPath      => \@path,
                      -ConfigFile      => "$goldCtlFile",
                      -ExtendedAccess  => 1,
                      -InterPolateVars => 1
                     );

my %goldCtl = $tmpCtl->getall();

my $tmpUser = $tmpCtl->obj("users");
my $goldUser = $goldCtl->obj("users");

 foreach my $person ($tmpUser->keys("users"))
 {
   foreach my $server ($tmpUser->keys("$person")->obj("server"))
   {
      {
         my $approved = $tmpCtl->obj("approvedBy");
         next if ($approved);
      }
   }
   $tmpCtl->save_file("$goldCtlFile");
 }
