Handle Dynamic body in Jmeter

The below beanshell code can handle dynamic body of the JMeter requests when used in beanshell preprocessor.


   import org.apache.commons.io.FileUtils;
    int countRoom = Integer.parseInt(vars.get("countRoom"));
    int countChild = Integer.parseInt(vars.get("countChild"));
    String FinalString = "";
    int agecounter = 0;
    List linesChildAge = FileUtils.readLines(new File(vars.get("ChildAgeCsv")));
    List linesRoomAdult = FileUtils.readLines(new File(vars.get("RoomAdultCsv")));
    
    for (int i = 0; i < countRoom; i++) {
    String Adult = linesRoomAdult.get(i);
    FinalString = FinalString + "\r\n          <room adult=\"" + Adult + "\">";
   
    for (int i = 0; i < countChild; i++)
    {
    String Age = linesChildAge.get(agecounter);
    agecounter++;
    FinalString = FinalString + "\r\n               <children>\r\n                    <child age=\"" + Age + "\"/>\r\n               </children>";
    }
    FinalString = FinalString + "\r\n          </room>";
    vars.put("FinalString", FinalString);
    }
