    One way is to use indexOf() to locate the tags, and delete() to remove them.

    See the documentation.

    To do this efficiently you would need to use indexOf(String str, int fromIndex) in a loop to ensure you removed multiple tags – and be careful how you update fromIndex after removing a tag! The simpler but inefficient way would be to just call indexOf() repeatedly until you run out of matches, but this would keep restarting the search from the start of the String.

    Or you could convert the StringBuilder to a String, create a new String with the tags removed using replaceAll(), then create a new StringBuilder with the result. Although this initially seems unnecessarily ugly and inefficient, it’s probably less code, and clearer to read, if efficiency is not a priority.
