I want to parse an XML string and display it in a EditText but I can't, I not understand what could be the problem, please a bit help, my code :

private String xmlc = "<game><cel>5</cel><val>2</val></game>";

private CharSequence readXML(String xmlc2) throws XmlPullParserException {


    XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
    XmlPullParser xpp = factory.newPullParser();

    String results = "";
    String celda = "";
    String valor = "";

    xpp.setInput(new StringReader (xmlc2));
    int eventType = xpp.getEventType();
    String tagName = xpp.getName();

    try {       
        while (eventType != XmlPullParser.END_DOCUMENT) {

            if(tagName.equalsIgnoreCase("cell")){
                celda = xpp.nextText();
            } else if(tagName.equalsIgnoreCase("val")){
                valor = xpp.nextText();
            }       
            xpp.nextTag();      
        }       
    } catch (Exception e) {
        Toast.makeText(this, "error!", Toast.LENGTH_LONG).show();
    }
    return celda;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    EditText et02 = (EditText)findViewById(R.id.et02);
    EditText et03 = (EditText)findViewById(R.id.et03);

    TextView myXmlContent = (TextView)findViewById(R.id.xml_tv);
    String stringXmlContent;

    stringXmlContent = getAllXML();
    myXmlContent.setText(stringXmlContent);

}
public String getAllXML(){

    Activity activity = this;
    String str = "";

    //For file source
    //Resources res = activity.getResources();
    //XmlResourceParser xpp = res.getXml(R.xml.test);


    try {
        //For String source
        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
        factory.setNamespaceAware(true);
        XmlPullParser xpp = factory.newPullParser();
        xpp.setInput(new StringReader(xmlc)); 

        xpp.next();
        int eventType = xpp.getEventType();                        

          while (xpp.getEventType()!=XmlPullParser.END_DOCUMENT) {
              if (xpp.getEventType()==XmlPullParser.START_TAG) {
                  if (xpp.getName().equals("cel")) {
                      str += "\ncell : "+xpp.nextText();
                  }
                  if (xpp.getName().equals("val")) {
                      str += "\nval : "+xpp.nextText();                       
                  }
              }
              xpp.next();

          e.printStackTrace();
    }
    return str;
}

And what's the problem? –  Egor Apr 22 at 7:53
 
You're using xmlc2 in your code instead of xmlc (if its not in an other class) und search for "cell" instead of "cel" like in your xml. –  luxer Apr 22 at 8:10
 
i do not know how to retrieve the values ​​"celda" and "valor" for display in the textview, also i add "Toasts" in the bucle while to display the values ​​but I do not show anything. In short I want to send a parameter as input and get 2 values as output. –  user2287189 Apr 22 at 9:00
 
i'm trying this for see the tags : String celda = xpp.nextText(); Toast.makeText(this, celda, Toast.LENGTH_LONG).show(); ...is wrong or ok ? –  user2287189 Apr 22 at 9:05
 
You should better debug your application in eclipse with breakpoints. Toasts are not the best choise. Or use Log.d("LOGTAG", "some msg here"); you can read this in the ddms. –  rekire Apr 22 at 9:15

SAX parser is way much efficient and Faster than Pullparser. SAX is always the best option when parsing XML in android. you can use this tutorial for SAX parsing
