This works.

#!/usr/bin/perl -w
use strict;

my (%ipkey,$value,$key);
my $count = 0;
my @rawdata = ('key1','value1','key2','value2','key3','value3');

foreach (@rawdata) {
        if ($count == 0) {
                $key = $_;
                $count++;
                next;
        }else{
                $value = $_;
                $ipkey{$key} = $value;
                $count = 0;
        }
}<\code>

  DB<4> x %ipkey
0  'key2'
