Hi Lasindu,
I wrote a sample that does what you expect. Please check the attached.

BufferedReader reader = null;
try {
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder domBuilder = domFactory.newDocumentBuilder();
Document newDoc = domBuilder.newDocument();
// Root element

newDoc.appendChild(rootElement);

int line = 0;
String text = null;
headers.add("val1");

String next = st.nextToken();
rowValues[index++] = next.trim();
}
//String[] rowValues = text.split(",");

rootElement.appendChild(rowElement);
for (int col = 0; col < headers.size(); col++) {
