I am so sorry, i never meant to beat the bush around. Its just that this thing is gettin on my nerve. Well the ans for your last question is i get <META NAME="TITLE" CONTENT="Karger Publishers" /> when i should get <META NAME="TITLE" CONTENT="Effects of Body Position on the Carbon Monoxide Diffusing Capacity in Patients with Chronic Heart Failure: Relation to Hemodynamic Changes" /> Thats all is my problem

What is this line supposed to do:

$url =~ s/&/=/g ;

Are you sure that you want to replace all & in your URL with =? If I remove that line, and much other unnecessary cruft, I see the complete HTML and especially also the relevant META tags:

use strict;
use LWP::Simple;


#Parsing the http file for the required fields
my $url = 'http://content.karger.com/ProdukteDB/produkte.asp?Aktion=Sh
+owAbstract&ArtikelNr=6735&Ausgabe=224691&ProduktNr=223832';
#$url =~ s/&/=/g ;
#my @url_mod = split('=', $url);

#checking for url and increasing article no.

warn "Downloading $url";
my $html = get $url;
print $html;
[download]

Thanks a lot, that works fine. Now i need to increase no. of Abstract&ArtikelNr , and get data for about 700 numbers.I used split to get the id, so that i can increase and get data.Is there other way to do it.
