How to count repeated strings in a line?

Hello,

 

Could you someone show me how to count repeated string in a line?

 

 string a = "Hello how are you Hello, Hello, Hello. Hello"

 

I would like to count how many "Hello" in the  string.

 

I tried to use aqString["Find"](a,"Hello");

 

but it just found the 1st one only.

    wrote a function in JScript as follows

    function abcd(){
var stringA = "Hello how are you Hello, Hlleo, Hello, Hello. Hello";
var HelloCount =0;
var startingAt =0;

  do {
      startingAt = aqString.Find(stringA, 'Hello', startingAt, false)+1;
      HelloCount = HelloCount+1;  }
  while (startingAt<=aqString.FindLast(stringA, 'Hello', false));

Log.Message(HelloCount);
}

      I got the solution.

       

      However, thank you very much.

    Here's another solution using a regular expression:

    var str = "Hello how are you Hello, Hello, Hello. Hello";
var regexp = /Hello/g;
var count = 0;

var matches = str.match(regexp);
if (matches != null)
  count = matches.length;

Log.Message(count);  // 5
