Hi Monks!
I am working on this weather script and I am fetching 15 zip codes as an example of my issue. The issue is that every time I run the code I have random missing values, am I doing something wrong on the Perl side, is there a better way of doing this? Here is a code sample and you can see these random missing values on the "$city" variable if you ran this.
#!/usr/bin/perl -w

use strict;
use CGI qw(-oldstyle_urls :standard);
use XML::TreePP;
use XML::XPath;
use XML::Simple;
use Data::Dumper;
use Date::Format;
use Date::Parse;


my $q = new CGI;

$| = 1;

my @zipcode = qw(02151 01908 02638 02669 02670 02536 02642 02574 02332
+ 02601 02045 01930 02152 27943 02169);

my ($currtempf, $currtempc, $currhumidity, $currcondition, $currwind, 
+$todayhigh, $todaylow, $todaycond, $tomorrowcond);
my ($city, $url, $tpp, $tree);


foreach my $zip(@zipcode) {

  next unless $zip =~ /^(\d{5})$/;

  $url = "http://www.google.com/ig/api?weather=".$zip ;
  $tpp = XML::TreePP->new();
  $tree = $tpp->parsehttp( GET => $url );

   $city = $tree->{xml_api_reply}->{weather}->{forecast_information}->
+{city}->{"-data"} || '';
   
   $currtempf =$tree->{xml_api_reply}->{weather}->{current_conditions}
+->{temp_f}->{"-data"} || '';
   $currtempc =$tree->{xml_api_reply}->{weather}->{current_conditions}
+->{temp_c}->{"-data"} || '';
   $currhumidity =$tree->{xml_api_reply}->{weather}->{current_conditio
+ns}->{humidity}->{"-data"} || '';
   $currcondition =$tree->{xml_api_reply}->{weather}->{current_conditi
+ons}->{condition}->{"-data"} || '';
   $currwind =$tree->{xml_api_reply}->{weather}->{current_conditions}-
+>{wind_condition}->{"-data"} || '';
   $todayhigh =$tree->{xml_api_reply}->{weather}->{forecast_conditions
+}->[0]->{high}->{"-data"} || '';
   $todaylow =$tree->{xml_api_reply}->{weather}->{forecast_conditions}
+->[0]->{low}->{"-data"} || '';
   $todaycond =$tree->{xml_api_reply}->{weather}->{forecast_conditions
+}->[0]->{condition}->{"-data"} || '';
   $tomorrowcond =$tree->{xml_api_reply}->{weather}->{forecast_conditi
+ons}->[1]->{condition}->{"-data"} || '';

   
   print "**City=$city** - Url=**$url**\n";

}

Thanks for looking and the help!!!
