How can I find a number in a string using Flex?

I want to replace a number with a character at runtime like this:

Input:

ask 1234 question

Result:

ask * question

What is the best way to accomplish this?

From stackoverflow

• You could use a regular expression.

• Use a Regex to match a number and then do a string replace. Something along the lines of:

  var str:String = "ask 1234 question"; // your string
  var pattern:RegExp = /\d+/ ; // a regular expression that matches numbers
  trace(str.replace(pattern, "*"));
  

  Look up the flex 3.0 documentation for both String and Regex. Happy coding!
