Question

I want to remove any substring(s) in a string that begins with ‘galery’ and ends with ‘jssdk));’

For instance, consider the following string:
Galery something something…. jssdk));

I need an algorithm that removes ‘something something….’ and returns ‘Galery jssdk));’

This is what I’ve done, but it does not work.

newsValues[1].replaceAll("Galery.*?jssdK));", "");

Answer 1

Could probably be improved, I’ve done it fast:

  public static String replaceMatching(String input, String lowerBound, String upperBound{
    Pattern p = Pattern.compile(".*?"+lowerBound+"(.*?)"+upperBound+".*?");
    Matcher m = p.matcher(input);
    String textToRemove = "";

    while(m.find()){
        textToRemove = m.group(1);
    }
    return input.replace(textToRemove, "");
}

UPDATE Thx for accepting the answer, but here is a smaller reviewed version:

 public static String replaceMatching2(String input, String lowerBound, String upperBound){
      String result = input.replaceAll("(.*?"+lowerBound + ")" + "(.*?)" + "(" + upperBound + ".*)", "$1$3");
      return result;
 }

The idea is pretty simple actually, split the String into 3 groups, and replace those 3 groups with the first and third, droping the second one.
