Thanks Hauke for the solution! That works but script takes a lot time in providing the output. Can this be reduced? Gzipped file is of 45MB. Total children (Offer) are 158K.

And, second question wasn't related to the first; that was different. Here is the code snippet. 
my $file = 'Offerfeed_11742413_uk.full.xml.gz';
my $z = IO::Uncompress::Gunzip->new($file) or die "gunzip failed: $IO:
+:Uncompress::Gunzip::GunzipError\n";

my $twig = new XML::Twig;    ## Get twig object
$twig->parse($z);    ## parse the file to build twig


my $root = $twig->root;        ## Get the root element of twig
my @elements = $root->children;    ## Get elements list of twig

my $ct = 0;
foreach my $e (sort @elements){
    my $cpc = ($e->first_child('EstimatedCPC')->text)*100;
    print $cpc,"\n";
    $ct++;
}
print $ct,"\n";
