Parsing XML with same name tags giving null in Android

Question

I am facing a problem in parsing the following XML:

<key>key 1</key>
<string>string 1</string>
<key>key 2</key>
<string>string 2</string>
<key>key 3</key>
<string>string 3</string>

I have written the following code but I get data only of the first tag in TextView, not the data of tags string2 and string 3. How to parse XML with same name tags?

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final Context mContext = this;
    TextView tv = (TextView) findViewById(R.id.info);

    try {      
         DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
         DocumentBuilder db = dbf.newDocumentBuilder();
         AssetManager assetManager = mContext.getAssets();
         InputStream inputStream = assetManager.open("abc.xml");   
         Document doc=db.parse(inputStream);
         doc.getDocumentElement().normalize();
         NodeList nodeList = doc.getElementsByTagName("string"); 


 for (int i = 0; i < nodeList.getLength(); i++) { 
     tv.setText( "\n\n"+ nodeList.item(i).getChildNodes().item(i).getNodeValue()+"\n"); 
     }


        } catch (Exception e) {
          System.out.println("Pasing Excpetion = " + e);
        }


}

May be your starts from this condition...change your condition from...

for (int i = 0; i < nodeList.getLength(); i++) {

to...

for (int i = 0; i < nodeList.getLength()-1; i++) {

Update:

Change this....

tv.setText( "\n\n"+ nodeList.item(i).getChildNodes().item(i).getNodeValue()+"\n");

to...

tv.setText( "\n\n"+ nodeList.item(i).getChildNodes().item(0).getNodeValue()+"\n");

Still getting data only in first tag.

user2011302 Over a year ago

How can I avoid some string tags to be included? Like, if I want to include string tags only after tags key 1, key 2 and key 4 and not the string tags after key 3 and key 5. I'll compare the value of key tags to a string, if condition satisfied, append the next node text, otherwise how to ignore the data of next node ? Please help.
