Hi, I am reading a file and fetching only the records which matches the condition. I am using the following code block to do the matching. This works fine for the 1st iteration of the outer loop. after that point its just not working .

Input to the script will be like this -c="field1","field2","field3=value1","field4=value2,value3"; all conditions are ANDed. field4 is vslue2 or value3 ....

I am building (%conwithposition) with the position of the fileds,operator and ref to values(array if more then one vslue)

i am using the following code block. My aim is to put all the line matching the 1st cond in a temp array and use the same for further checking.

i have problem while pushing line(record) into @arraynew. Its only giving reference. I want to build a two-dimentional array of matched record. 
my $arrayref =\@array;
my @arraynew;
foreach $key_pos(keys(%conwithposition)) {
    #print "KEYLOOP::(@{$conwithposition{$key_pos}}[1],@{$conwithposit
+ion{$key_pos}}[2])\n";#,$line[@{$conwithposition{$key_pos}}[0]])\n";
    $i=0;
    #print "ARR:@arraynew\n";
    file:for (@$arrayref) {
        my $match = 0;
        my @line = split /\t/;
        #print "Line:::@$arrayref\n";
        my @tmp;
        my ($op, $arg1, $arg2) = (@{$conwithposition{$key_pos}}[1],@{$
+conwithposition{$key_pos}}[2],$line[@{$conwithposition{$key_pos}}[0]]
+);
        $match = is_match($op,$arg2, $arg1);
        if ($match){
           push @tmp,@line[@sorted_cols];
           print "@tmp\n";
        }
         push @arraynew,[@tmp];
         $i++;
    }
   $arrayref = \@arraynew;
}
print "Result: @tmp\n";
sub is_match{
      my ($operator,$valuesrc,$inputval_ref)=@_;
      my $i;
      if (ref $inputval_ref eq 'SCALAR'){
         return 1 if ($valuesrc eq $$inputval_ref);
      }
      if (ref ($inputval_ref) eq 'ARRAY'){
         my @valuetomatch=@$inputval_ref;
         for $i(0 .. $#valuetomatch){
             return 1 if ($valuesrc eq $valuetomatch[$i]);
         }
      }
      return 0;
}

Can anybody correct my mistake? Thanks
