AS3 replace nth occurrence in string

Question

When I want to replace "abc" by "xyz" i use the following command:

str.split("abc").join("xyz");

But what if I have the following string "This is just a test string" and would like to replace only the second whitespace by "\n".

If i understands this correctly you want the resulting String look like this: "This is\njust a string"? — Johan Lindkvist

@Johan: yes. I want the second whitespace to be replaced by "\n". — vigri

To improve on @fsbmain's answer, n-th occurence can be replaced in using '/(( [^ ]+){3}) /' (http://regexr.com?33nm5):

var str:String = ("This is just a test string").replace(/(( [^ ]+){3}) /, "$1\n");
trace(str);

The output would be:

This is just a
test string

You can use this regExp:

    var str:String = ("This is just a test string").replace(/(.[^ ]+ .[^ ]+) /, "$1\n");
    trace(str);

output:

This is
just a test string
