Answer 1

    String str = "上证综指\n"
               + "5913.230点\n"
               + "+141.77(+2.46%)\n"
               + "深证成指\n"
               + "19344.154点\n"
               + "+80.12(+0.42%)\n"
               + "沪深300\n"
               + "5760.078点\n"
               + "+74.32(+1.31%)";
    System.out.println(str.replaceAll("([^\r\n]+)[\r\n]+([^\r\n]+)[\r\n]+(.+)","[$1]=$2 $3"));
