XML : Dependent Spinner in XML DOM parser

Want to populate the Spinner-2 on basis of Spinner-1 .Like if I select Newton then only Force and Apple not the other values and if I select Hiiii value then only ds should populate on the Spinner-2 like wise.

My below code successfully populate the values from the xml url IN BOTH THE spinner-1 and SPINNER-2 but not with the particular way the values which i showed in the above image.

  title = new ArrayList<String>();          title2 = new ArrayList<String>();            button = (Button) findViewById(R.id.button1);          spinner = (Spinner) findViewById(R.id.spinner1);          spinner.setOnItemSelectedListener(this);            spinner2 = (Spinner) findViewById(R.id.spinner2);          spinner2.setOnItemSelectedListener(this);          dateFormatter = new SimpleDateFormat("dd-MM-yyyy", Locale.US);          findViewsById();            setDateTimeField();          if (android.os.Build.VERSION.SDK_INT > 9) {              StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();              StrictMode.setThreadPolicy(policy);          }              button.setOnClickListener(new OnClickListener()          {                @Override              public void onClick(View v) {                  // TODO Auto-generated method stub                    parse();                    from_adapter=new ArrayAdapter<String>(getBaseContext(),android.R.layout.simple_spinner_item, title);                  from_adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);                    from_adapter2=new ArrayAdapter<String>(getBaseContext(),android.R.layout.simple_spinner_item, title2);                  from_adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);                      spinner.setAdapter(from_adapter);                  spinner2.setAdapter(from_adapter2);                  }                private Object from_adapter(int i) {                  // TODO Auto-generated method stub                  return null;              }            });          }            public void onItemSelected(AdapterView<?> parent, View view, int pos,              long id) {          Toast.makeText(parent.getContext(), ""+spinner.getSelectedItem().toString().trim(),                  Toast.LENGTH_LONG).show();      }        public void onNothingSelected(AdapterView<?> arg0) {      }        protected void parse() {          // TODO Auto-generated method stub              try {                URL url = new URL(                      "URL Link");              DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();              DocumentBuilder db = dbf.newDocumentBuilder();              Document doc = db.parse(new InputSource(url.openStream()));              doc.getDocumentElement().normalize();                NodeList nodeList = doc.getElementsByTagName("AAAA");              for (int i = 0; i < nodeList.getLength(); i++) {                    Node node = nodeList.item(i);                           Element fstElmnt = (Element) node;                  NodeList nameList = fstElmnt.getElementsByTagName("a:W");                  Element nameElement = (Element) nameList.item(0);                  nameList = nameElement.getChildNodes();                               title.add(((Node) nameList.item(0)).getNodeValue());                }              NodeList nodeList2 = doc.getElementsByTagName("a:AAAA");              for (int i = 0; i < nodeList2.getLength(); i++) {                    Node node = nodeList2.item(i);                           Element fstElmnt = (Element) node;                  NodeList nameList = fstElmnt.getElementsByTagName("a:R");                  Element nameElement = (Element) nameList.item(0);                  nameList = nameElement.getChildNodes();                           title2.add(((Node) nameList.item(0)).getNodeValue());                }              Set<String> set = new LinkedHashSet<String>(title);              title = new ArrayList<String>(set);               Set<String> set2 = new LinkedHashSet<String>(title2);              title2 = new ArrayList<String>(set2);            } catch (Exception e) {              System.out.println("XML Pasing Excpetion = " + e);          }        }
