The required records have the tag "item". Each record has elements with the tags "title", "description", "link", "pubDate" and "guid".

Take "item" as the entryTag. Take "title", "description", "link", "pubDate" and "guid" as entryKeys.

Method 1.

          String entryTag = "item";
          ArrayList<String> entryKeys = new ArrayList<>();
          entryKeys.add("title");
          entryKeys.add("description");
          entryKeys.add("link");
          entryKeys.add("pubDate");
          RssXmlProcessor xmlProcessor = new RssXmlProcessor(entryTag, entryKeys);
          xmlProcessor.execute(xml_string, new RssXmlToHashMapListHandler() {
              @Override
              public void onStart() {

              }

              @Override
              public void onSuccess(List<HashMap<String, String>> items) {
                    //consuming the processed items using the same keys
                    for(HashMap<String, String> item: items) {
                          String title = item.get("title");
                          String description = item.get("description");
                          String link = item.get("link");
                          String pubDate = item.get("pubDate");
                    }
              }

              @Override
              public void onFail(Exception ex) {

              }

              @Override
              public void onComplete() {

              }
          });

Method 2.

          String entryTag = "item";
          ArrayList<String> entryKeys = new ArrayList<>();
          entryKeys.add("title");
          entryKeys.add("description");
          entryKeys.add("link");
          entryKeys.add("pubDate");
          RssXmlProcessor xmlProcessor = new RssXmlProcessor(entryTag, entryKeys);
          xmlProcessor.execute(xml_string, new RssXmlToJSONListHandler() {
              @Override
              public void onStart() {

              }

              @Override
              public void onSuccess(List<JSONObject> items) {
                    //consuming the processed items using the same keys
                    for(JSONObject item: items) {
                        try {
                            String title = item.getString("title");
                            String description = item.getString("description");
                            String link = item.getString("link");
                            String pubDate = item.getString("pubDate");
                        }catch (Exception ex){}
                     }
              }

              @Override
              public void onFail(Exception ex) {

              }

              @Override
              public void onComplete() {

          });

Method 3.

          String entryTag = "item";
          ArrayList<String> entryKeys = new ArrayList<>();
          entryKeys.add("title");
          entryKeys.add("description");
          entryKeys.add("link");
          entryKeys.add("pubDate");
          RssXmlProcessor xmlProcessor = new RssXmlProcessor(entryTag, entryKeys);
          xmlProcessor.execute(xml_string, new RssXmlToJSONArrayHandler() {
              @Override
