Hi Poj, Thanks a lot for the refined code, It looks prettier. Just need to know the purpose of the below part of the code. But your code is working very well. 
my @nodes = ();
while (<SRV>){
  # skip blank lines
  s/\s+$//;
  s/^\s+//;
  next if /^$/;
  
  # validate records
  if (/.+/){ # change to suit
    push @nodes,$_;
  } else {
    printLog("ERROR Invalid record '$_'");
  }
}
