traverse nested xml file android

I'm trying to traverse a nested XML string in Android that looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Results>
<Result>
<Questions>
<Question>Where can I get the local variable</Question>
<Answer>In the local method</Answer>
<AverageRating>3.0</AverageRating>
</Questions>
<Keywords>
<Keyword>Methods</Keyword>
<Keyword>Returns</Keyword>
<Keyword>Void</Keyword>
</Keywords>
</Result>
<Result>
<Questions>
<Question>How can I do a nested for loop</Question>
<Answer>Easy</Answer>
<AverageRating>2.5</AverageRating>
</Questions>
<Keywords>
<Keyword>Methods</Keyword>
<Keyword>Returns</Keyword>
<Keyword>Void</Keyword>
<Keyword>Methods</Keyword>
<Keyword>Returns</Keyword>
</Keywords>
</Result>
with the following Android code:
try
{
//Creates the document
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(serverResult)));
//optional, but recommended
//read this - http://stackoverflow.com/questions/13786607/normalization-in-dom-parsing-with-java-how-does-it-work
document.getDocumentElement().normalize();
//Look at root node's type (e.g. <query> or <login> or <add>)
String rootNode = document.getDocumentElement().getNodeName().toString();
if (rootNode.equals("Results"))
{
String Question = "";
String Answer = "";
String AverageRating = "";
float rating = 0;
String keyword = "";
NodeList nList = document.getElementsByTagName("Result");
for (int i = 0; i < nList.getLength(); i++)
{
Node nodes = nList.item(i);
if (nodes.getNodeType() == Node.ELEMENT_NODE)
{
Element element = (Element) nodes;
NodeList list = document.getElementsByTagName("Questions");
for (int value = 0; value < list.getLength(); value++)
{
Node node = list.item(value);
if (node.getNodeType() == Node.ELEMENT_NODE)
{
Element eElement = (Element) node;
Question = getValue("Question", eElement);
Answer = getValue("Answer", eElement);
AverageRating = getValue("AverageRating", eElement);
rating = Float.parseFloat(AverageRating);
}
}
}
NodeList keywordNode = document.getElementsByTagName("Keywords");
String keywords = "";
for (int y = 0; y < keywordNode.getLength(); y++)
{
Node node = keywordNode.item(y);
if (node.getNodeType() == Node.ELEMENT_NODE)
{
Element element = (Element) node;
NodeList ModList = document.getElementsByTagName("Keyword");
int count = ModList.getLength();
for (int b = 0; b < count; b++)
{
keyword = element.getElementsByTagName("Keyword").item(b).getTextContent();
keywords = keywords + keyword + "\n";
}
}
items.add(new Question(Question, Answer, rating, keywords));
}
}
}
}
catch (Exception e)
{
String s = e.getMessage();
publishProgress(s);
}
What I'm trying to achieve is for each question of each respective results in the Result tag of my XML, I want to get the question (and it's details) and the respective keywords, adding each to the Question class, then repeat for the next result from Results tag. Can someone please help with my code and show me where I'm going wrong?

Try importing these:
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import org.xmlpull.v1.XmlPullParserFactory;
by downloading them at this site: http://www.xmlpull.org/
Then, try a code structure like this:
String XMLin;
XmlPullParserFactory factory;
String tag;
ArrayList<Question> questions = new ArrayList<Question>();
try {
XMLin = readString(instream);
} catch (IOException e1) {
// TODO Auto-generated catch block
XMLin = "Something went wrong";
}
try {
// Set up the Class that will be parsing the xml file
factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = factory.newPullParser();
xpp.setInput(new StringReader (XMLin));
// Get the first event type
int eventType = xpp.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
// While we have not reached the end of the document, check for start tags
if (eventType == XmlPullParser.START_TAG) {
tag = xpp.getName();
if (tag.equals("Questions") && eventType == XmlPullParser.START_TAG) {
Question question = new Question();
do {
if (tag.equals("Question")) {
// Add question text to question
eventType = xpp.next();
String text = xpp.getText(); // Text between tags
} else if (tag.equals("Answer")) {
eventType = xpp.next();
String text = xpp.getText(); // Text between tags
} else if (tag.equals("AvergaeRating") {
eventType = xpp.next();
String text = xpp.getText(); // Text between tags
}
eventType = xpp.next();
if (eventType == XmlPullParser.TEXT) {
tag = xpp.getText();
} else {
tag = xpp.getName();
}
} while (!tag.equals("Questions"))
questions.add(question);
}
}
}
This is a modified example of something I used to parse through XML. Essentially, check for the tag name and event (whether it's a start tag or end tag, etc) and then perform that actions you want depending on those two values, such as add the text inbetween into a Question object or whatnot.

I managed to use this code:
try
{
//Creates the document
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(serverResult)));
//optional, but recommended
//read this - http://stackoverflow.com/questions/13786607/normalization-in-dom-parsing-with-java-how-does-it-work
document.getDocumentElement().normalize();
//Look at root node's type (e.g. <query> or <login> or <add>)
String rootNode = document.getDocumentElement().getNodeName().toString();
if (rootNode.equals("Results"))
{
//Any methods which need to be called that will be used to query the database
//Always sending the String XML through as a parameter
//Look at the child node
String Question = "";
String Answer = "";
String AverageRating = "";
float rating = 0;
String keywords = "";
NodeList nList = document.getElementsByTagName("Questions");
System.out.println("----------------------------");
for (int temp = 0; temp < nList.getLength(); temp++)
{
Node nNode = nList.item(temp);
System.out.println("\nCurrent Element :" + nNode.getNodeName());
if (nNode.getNodeType() == Node.ELEMENT_NODE)
{
Element eElement = (Element) nNode;
Question = getValue("Question", eElement);
Answer = getValue("Answer", eElement);
AverageRating = getValue("AverageRating", eElement);
rating = Float.parseFloat(AverageRating);
NodeList List = document.getElementsByTagName("Keywords");
for (int a = 0; a < List.getLength(); a++)
{
Node node = List.item(temp);
if (node.getNodeType() == Node.ELEMENT_NODE)
{
Element element = (Element) node;
String Keyword = element.getElementsByTagName("Keyword").item(0).getTextContent();
keywords = keywords + Keyword + "\n";
}
}
}
items.add(new Question(Question, Answer, rating, keywords));
}
}
}
catch (IOException e) {
e.printStackTrace();
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
which then get's each individual question (and all their information - question, answer, rating) and well as the respective keywords for that question and add to a Question object, then loop back. I wasn't putting the keywords XML parse within the questions for loop. Hopefully this helps someone who is struggling with similar problems.

android XML Parsing with multiple child nodes

I am trying to parse an xml but it is returning all the chld nodes that have tag "nature".But I just want to only those nodes whose cat is selcted.
My xml looks like :-
<NatureList>
<NatureCategory cat="Crimes Against People">
<Nature>
<Name>Aggravated Assault</Name>
</Nature>
<Nature>
<Name>Annoyance Phone Calls</Name>
</Nature>
<NatureCategory>
<NatureCategory ...NatureCategory>
and parsing is done like this :
Document doc = XmlParser.getDomElement(xml);
NodeList n = doc.getElementsByTagName("NatureCategory");
try {
for(int i=0; i<n.getLength();i++)
{
Element e = (Element) n.item(i);
if(e.getAttribute("cat").equals(spinn.getSelectedItem().toString()))
{
Log.i("sub1", spinn.getSelectedItem().toString() );
NodeList n1 = doc.getElementsByTagName("Nature");
for(int j=0; j<n1.getLength();j++)
{
Element e1 = (Element) n1.item(j);
subcategory.add(getValue(e1, "Name"));
}
}
// subcategory.add()
}
}

nodes1 = doc.getElementsByTagName("NatureList");
for (int i = 0; i < nodes1.getLength(); i++) {
ObjectClass cgro = new ObjectClass();
Element e = (Element)nodes1.item(i);
cgro.NatureCategory = XMLfunctions.getValue(e, "NatureCategory");//here u can compare with your spinner string if match then parse this NatureCategory or save oe any logic which u like
nodes1a = doc.getElementsByTagName("cat");
for(int j = 0; j < nodes1a.getLength(); j++ ){
ObjectClass1 cgro1 = new ObjectClass1();
Element e2= (Element) nodes1a.item(j);
cgro1.cat= XMLfunctions.getCharacterDataFromElement(e2);
ArrayListClass.ItemList1.add(cgro1);
}
ArrayListClass.ItemList2.add(cgro);
}
and class use for this
public class XMLfunctions {
public final static Document XMLfromString(String xml){
Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(xml));
doc = db.parse(is);
} catch (ParserConfigurationException e) {
System.out.println("XML parse error: " + e.getMessage());
return null;
} catch (SAXException e) {
System.out.println("Wrong XML file structure: " + e.getMessage());
return null;
} catch (IOException e) {
System.out.println("I/O exeption: " + e.getMessage());
return null;
}
return doc;
}
/** Returns element value
* #param elem element (it is XML tag)
* #return Element value otherwise empty String
*/

I think if form your XML like this it would be better:
<NatureList>
<NatureCategory>
<cat>Crimes Against People</cat>
<Nature>
<Name>Aggravated Assault</Name>
</Nature>
<Nature>
<Name>Annoyance Phone Calls</Name>
</Nature>
<NatureCategory>
Then get the cat tag and then test it.

How to get RTSP Links Android

Am having you-tube links like http://www.youtube.com/v/YR71GnQ4CU4?f=videos&app=youtube_gdata , then how to convert it to RTSP format to play in VideoView.
Am searching gdata api with this: http://gdata.youtube.com/feeds/api/videos?&max-results=20&v=2&format=1&q="+ URLEncoder.encode(activity.criteria) but i cant find how to get related RTSP url.

I got my answer ..thanx to this
Element rsp = (Element)entry.getElementsByTagName("media:content").item(1);
String anotherurl=rsp.getAttribute("url");
In gdata api only we are getting this type of links : rtsp://v3.cache7.c.youtube.com/CiILENy73wIaGQlOCTh0GvUeYRMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp
These are playing in VideoView.

This might be a little late. Here is some working code for people having trouble.
try{
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new URL(url).openStream());
doc.getDocumentElement ().normalize ();
NodeList content = doc.getElementsByTagName("media:content");
for(int i=0; i<content.getLength(); i++){
Element rsp = (Element)content.item(i);
result.add(rsp.getAttribute("url"));
}
}catch(Exception e){
Log.e("log_tag", "Error in http connection "+e.toString());
}

Below is the function which can get you RTSP link for the youtube video
public static String getUrlVideoRTSP(String urlYoutube) {
try {
