converting to XML file

[midan myaa]

Hi i am buildding a WEb based Questionnaire and i am trying to receive text from a jsp page i have created and print it out as XML. I have a createHeader.jsp file that asks for the number of questions you want to create so when i click it it take me to createQuestions.jsp where i can enter text. ie
Enter a Question, 4 choices and the Right anwser. When i submit it takes me to writeXML.jsp which write it as an XML file...

<%
String Tquestion = request.getParameter("questionText");

String answer1 = request.getParameter("choice1");
String answer2 = request.getParameter("choice2");
String answer3 = request.getParameter("choice3");
String answer4 = request.getParameter("choice4");
String Canswer = request.getParameter("cAnswer");
%>

<%
String home ="C:\\Tomcat\\FYProject\\lib\\";
String filename = request.getParameter("file");
String extension = ".xml";
String filePath = home + filename + extension;
BufferedWriter bw = new BufferedWriter(new FileWriter(filePath,true));
for(int i=0;i<2; i++) {

%>
<%
bw.write("<mc_QuestionType>");
bw.newLine();
bw.write(" <questionText>" +Tquestion+ "</questionText>");
bw.newLine();
bw.write(" <choice>" +answer1+ "</choice>");
bw.newLine();
bw.write(" <choice>" +answer2+ "</choice>");
bw.newLine();
bw.write(" <choice>" +answer3+ "</choice>");
bw.newLine();
bw.write(" <choice>" +answer4+ "</choice><br>");
bw.newLine();
bw.newLine();
bw.write(" <answer>" +Canswer+ "</answer>");
bw.newLine();
bw.write("</mc_QuestionType>");
bw.newLine();

}
bw.close();
%>
So this gets the parameter names of the TEXTAREA from the createQuestion.jsp
The problem is that it wites as XML for just the first set(ie Question, the 4 Choices and the Answer) I know this code does what it is doing but can anyone help me so i it will write it as XML for all the Questins i want to create
Thanx

does all the question elements have the same name?
like parameter questionText??
then u can do something like this

  
String[] values      = request.getParameterValues("questionText");
//do similar for the options and answers
if(values!=null)
{
for ( int i=0;i<values.length;i++) 
{
String data    = values[i];
//now do what u want to do 
}

hope it may help

Incidently, I think that an empty Text area will return an empty string, not a null.
