very thanks for such clear answer. Ya, I understand that regex now. I am grouping all the string expect last element (By using pipe). And the grouped string saved into $1 by using "(".

 $str =~ s/(.*)\|.*\|.*/$1/;

now it will remove the last two elements. and it continues. Suppose if I have 60 "|" in my string and I want to delete last 22 then how can I use this. I cant write 22 pipes like "\|.*\|.*".
