Well you could find out if and where to append with

int startNamespace = s.indexOf(namespace);

If you really want to use replaceAll (using regex), you can do the following (the search string contains metacharacters so needs quoting)

String nq = "\\Q" + namespace + "\\E";
s = s.replaceAll(nq, namespace + result);

You need to use return value of replaceAll() method. replaceAll() does not replace the characters in the current string, it returns a new string with replacement.

String objects are immutable, their values cannot be changed after they are created.
You may use replace() instead of replaceAll() if you don't need regex.

 String str = "abcd=0; efgh=1";
    String replacedStr = str.replaceAll("abcd", "dddd");

Open in new window

System.out.println(str);
    System.out.println(replacedStr);

outputs

abcd=0; efgh=1
dddd=0; efgh=1
