Come posso analizzare XML Android?

Question

Ho problemi nell'analisi del mio XML, ho provato molte cose.

Ho xml come questo.

<question id="1" text="Zodiac Sign" > 
    <option id="1" >Aries</option> 
    <option id="2" >Taurus</option> 
    <option id="3" >Gemini</option> 
    <option id="4" >Cancer</option> 
    <option id="5" >Leo</option> 
    <option id="6" >Virgo</option> 
    <option id="7" >Libra</option> 
    <option id="8" >Scarpio</option> 
    <option id="9" >Sagitarius</option> 
    <option id="10" >Capricorn</option> 
    <option id="11" >Acqauarius</option> 
</question><question id="2" text="Home Town" > 
</question><question id="3" text="Current Locaion" > 
</question><question id="4" text="Nationality" ></question> 
<question id="5" text="Height" ></question> 
<question id="6" text="Build(optional)" > 
    <option id="13" >Slim</option> 
    <option id="14" >Athletic</option> 
    <option id="15" >Few Pounds Extra</option> 
    <option id="16" >Obese</option> 
</question><question id="7" text="Hair Color" > 
</question><question id="8" text="Color Of Eyes" > 
    <option id="23" >Black</option> 
    <option id="24" >Brown</option> 
    <option id="25" >Blue</option> 
</question><question id="9" text="Smoking Habits" > 
</question> 

ho bisogno di ottenere domande e voglio salvarli in un array e poi ci sono alcune domande che hanno opzioni come tag bambino, voglio aggiungere queste opzioni in un altro array con il riferimento a questa domanda id .

Come posso analizzare effettivamente questo xml.?

Ho cercato di farlo usando XMLPullParser

Ecco il mio codice, ma non il suo lavoro.

StringBuilder sb = new StringBuilder(); 
    int depth = 1; 
    while (depth != 0) { 
     switch (parser.next()) { 
     case XmlPullParser.END_TAG: 
      depth--; 
      if (depth > 0) { 
       sb.append("</" + parser.getName() + ">"); 
      } 
      break; 
     case XmlPullParser.START_TAG: 
      depth++; 
      StringBuilder attrs = new StringBuilder(); 
      for (int i = 0; i < parser.getAttributeCount(); i++) { 
       attrs.append(parser.getAttributeName(i) + "=\"" 
         + parser.getAttributeValue(i) + "\" "); 
      } 
      sb.append("<" + parser.getName() + " " + attrs.toString() + ">"); 
      break; 
     default: 
      sb.append(parser.getText()); 
      break; 
     } 
    } 
    payload = sb.toString();

Ho creato il mio parser per analizzare questo xml.

Ecco il codice

public class ProfileHome extends Activity { 

    public String id=""; 
    public String text=""; 
    public ArrayList<String>option = new ArrayList<String>(); 
    public String singleoption=""; 

    List<Questions> q; 
    private Questions question = new Questions(); 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.profile_home); 
     String payload = "<question id=\"1\" text=\"Zodiac Sign\" ><option id=\"1\" >Aries</option><option id=\"2\" >Taurus</option><option id=\"3\" >Gemini</option><option id=\"4\" >Cancer</option><option id=\"5\" >Leo</option><option id=\"6\" >Virgo</option><option id=\"7\" >Libra</option><option id=\"8\" >Scarpio</option><option id=\"9\" >Sagitarius</option><option id=\"10\" >Capricorn</option><option id=\"11\" >Acqauarius</option></question><question id=\"2\" text=\"Home Town\" ></question><question id=\"3\" text=\"Current Locaion\" ></question><question id=\"4\" text=\"Nationality\" ></question><question id=\"5\" text=\"Height\" ></question><question id=\"6\" text=\"Build(optional)\" ><option id=\"13\" >Slim</option><option id=\"14\" >Athletic</option><option id=\"15\" >Few Pounds Extra</option><option id=\"16\" >Obese</option></question><question id=\"7\" text=\"Hair Color\" ></question><question id=\"8\" text=\"Color Of Eyes\" ><option id=\"23\" >Black</option><option id=\"24\" >Brown</option><option id=\"25\" >Blue</option></question><question id=\"9\" text=\"Smoking Habits\" ></question>"; 
     q = new ArrayList<Questions>(); 

     if(payload.contains("question")) 
      { 

       for(int i=0;i<payload.length();i++) 
        { 
        Questions ques = new Questions(); 
        // check if question has come 
         if(payload.substring(i, i+8).equals("question")) 
         { 
          i=i+9; 
          // check for the id, text and options 
          for(int k=i;k<payload.length();k++) 
          { 
           if(payload.substring(k, k+9).equals("/question")) 
           { 
            q.add(ques); 

            k=k+9;

           }else if(payload.substring(k, k+4).equals("id=\"")) 
           { 
            //get id

           { 
            for(int j=k+6;j<payload.length();j++)

              id=""; 
              k=j+1; 
              text=""; 
              break; 
             }else 
             { 
              text= text + payload.substring(j, j+1); 
             } 
            } 
            //check for options

             { 
              for(int l=k;l<payload.length();l++) 
              { 
               if(payload.substring(k, k+11).equals("</question>")) 
               { 
                ques.setOptions(option); 
                q.add(ques); 
                k=k+11; 
                break; 
               } 
              //now get all options and their id's 
              for(int j=k+11;j<payload.length();j++) 
              {

               if(payload.substring(j, j+9).equals("</option>")) 
               { 
                option.add(singleoption); 
                singleoption=""; 
                k=j+9;

    @Override

     getMenuInflater().inflate(R.menu.profile_home, menu);
