Subject: How to count a word in a line

Hi,
I wonder if there is a way of counting a word in a line using ruby
regexp.
Such as how many "Hi"'s  in a line.
Let's say when I enter a line
"Hello and Hi there hey hear my Hi"
It should give me 2, because there are 2 "Hi"'s.
I have something like this but looks awkward.
while line=gets.chomp
 cnt = 0
 line.split.each {
   |v|
   if v == 'Hi' then
      cnt +=1
   end
 }
 break if cnt > 2
end

Thanks in advance
Yusuf Celik
