How can I replace it? I've been trying this:
string.replaceFirst(substring, "");
but it's not replacing, and as I am doing a recursive method, it's giving me a StackOverflowException..
Any idea?

String are immutable, which means you cannot change them once they are initialized.
The replaceFirst method creates a new string where the first instance is replaced by your replacement and returns it...the original string is never modified.
You're code should be something like this
string = string.replaceFirst(substring,"")

@BalusC-Would you mind taking a look at this ?: stackoverflow.com/questions/4532009/…
In addition to other replys that Strings are immutable, note that replaceFirst takes in a Regular Expression not a substring. (The two might be the same in some cases but not all). Either way this more than likely is unrelated to your StackOverflowException.

This method not modifying current String. It returns new string with replacement. String newString = string.replaceFirst(substring, "");

Use this:
string = string.replaceAll(substring, replacement_string).
