Oh, I didn't read the whole question. Regex.replace returns a new String. You need to do something like

class StringParser(val string: String){
    fun removeHTMLTags() = StringParser(Regex("<[^>]*>").replace(string, ""))
    fun removeSpecialCharacters() = StringParser(Regex("[^A-Za-z0-9 ]").replace(string, ""))
}
