code

ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String,String>>();

            XMLParser parser = new XMLParser();
            String xml = parser.getXmlFromUrl(URL); // getting XML

            Document doc = parser.getDomElement(xml); // getting DOM element

            NodeList nl = doc.getElementsByTagName(title);
               // looping through all item nodes <item>

            for (int i = 1; i < nl.getLength(); i++) {
                    // creating new HashMap
                    HashMap<String, String> map = new HashMap<String, String>();
                    Element e = (Element) nl.item(i);
                            // adding each child node to HashMap key => value
                    map.put(time, parser.getValue(e, time));
                    map.put(description, parser.getValue(e, description));
                    map.put(name, parser.getValue(e, name));
                            // adding HashList to ArrayList
                    menuItems.add(map);

             }
