how to parse the string of xml data in android

Question

I am new to android programming.My requirement is to invoke the web services.I successfully got the response from web services.how to parse the response in android.Give me solution.

This is the code for getting response:

 HttpResponse response = httpclient.execute(httppost);
           String str=response.getStatusLine().toString();

           System.out.println("========URL STATUS========"+str);

           HttpEntity r_entity = response.getEntity();

           if( r_entity != null ) {
               result = new byte[(int) r_entity.getContentLength()];
               if(r_entity.isStreaming()) {
                    is = new DataInputStream(r_entity.getContent());
                   is.readFully(result);

               }
           }

           httpclient.getConnectionManager().shutdown();
           String responsedata= (new String(result).toString());

First of all take a look at EntityUtils.toString(), and secondly: use same xml parser like SimpleXML or something else — Korniltsev Anatoly

The below sample is for dom parser.

 DocumentBuilderFactory dbf =DocumentBuilderFactory.newInstance();
 DocumentBuilder db = dbf.newDocumentBuilder();
 InputSource is = new InputSource();
 StringReader sr=new StringReader(result.toString());
 is.setCharacterStream(sr);
 Document doc = db.parse(is);
 NodeList nodes = doc.getElementsByTagName("your root tag");

 //get your other tag elements.

http://www.mkyong.com/java/how-to-read-xml-file-in-java-dom-parser/. Example of dom parser.

http://www.mkyong.com/java/how-to-read-xml-file-in-java-sax-parser/. Example of sax parser.

Dom is w3c based parser. Dom is slower than sax cause it uses tree node and has to be in mmeory. So parsing large data using DOM parser is not recommended.

SAX on the other hand is faster than dom. Recommended for large xml data.

The above links gives you examples of both. Use any of the above parser to parse and get values from the xml tags.

You can try to use SimpleXmlParser. It's a native android class. It's simpler than DOM xml parser.
