Welcome to JavaRanch

Please always use thread titles which say what the thread is about. "New to Java" doesn't attract attention.

Help Needed...


URL url = new URL(requestUrl.toString());
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String inputLine;
// System.out.println("-----RESPONSE START-----");
while ((inputLine = in.readLine()) != null) {
System.out.println(inputLine);



NodeList listOfPersons = inputLine.getElementsByTagName("Information");
int totalPersons = listOfPersons.getLength();
System.out.println("Total no of people : " + totalPersons);

for(int s=0; s<listOfPersons.getLength() ; s++){


Node firstPersonNode = listOfPersons.item(s);
if(firstPersonNode.getNodeType() == Node.ELEMENT_NODE){


Element firstPersonElement = (Element)firstPersonNode;

//-------
NodeList firstNameList = firstPersonElement.getElementsByTagName("Return_Msg");
Element firstNameElement = (Element)firstNameList.item(0);

NodeList textFNList = firstNameElement.getChildNodes();
System.out.println("First Name : " + ((Node)textFNList.item(0)).getNodeValue().trim());

Welcome to JavaRanch.

Please use one thread per question - when you have a new question, just start a new topic, and don't post it as an answer in an existing topic.

Also, use code tags when you post source code, that makes it much easier to read.

About your question: inputLine is a String. Class String does not have a method called getElementsByTagName, so what you are trying to do doesn't work. In fact, when your code reaches the line:

NodeList listOfPersons = inputLine.getElementsByTagName("Information");

then inputLine will be null and even if this code would compile, you'd get a NullPointerException. It looks like you want to parse an XML file. You'll need to put the data from the response in an XML Document and extract the data that you're looking for from that.
