Question

ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(url); // getting XML
int displayPerPage = 5; 
int TotalRows = xml.length();
Document doc = parser.getDomElement(xml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_ITEM);
// looping through all item nodes <item>

for (int i = 0; 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(KEY_NAME, parser.getValue(e, KEY_NAME));
    // adding HashList to ArrayList
    menuItems.add(map);
}

Just use nl.getLength(), it’ll return you the number of items in each tag.
