You explain with an example data. Now I tried with an example hash according to your description. If I understood your hash structure wrongly, you give the example data.
use strict;
use warnings;
use Data::Dumper;
my %hash=("logins" => [ { '1' => 'http://www.perlmonks.com/?node_id=90
+1658' , '2' => 'http://www.google.com' }, { '3'=> 'http://www.bksyste
+ms.co.in'}]);
#prints the structure of the hash
print Dumper \%hash;
print "==========================\n";
# getting the length of an array and going through each index of an ar
+ray
for (0 .. length @{$hash{'logins'}}) {
for my $key (keys%{$hash{'logins'}[$_]}) {
# printing key and value
print "Key: $key and Value:$hash{'logins'}[$_]{$key}\n";
+
}
print "==========================\n"
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
