static final String KEY_ITEM = "questions"; // parent node
static final String KEY_QUESTION = "question_id";
static final String KEY_QUESTIONNAME = "question_name";
static final String KEY_QUESTIONHINT = "question_hint";

XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); // getting XML
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++) {
    String name = parser.getValue(e, KEY_QUESTION); // name child value
    String cost = parser.getValue(e, KEY_QUESTIONNAME); // cost child value
    String description = parser.getValue(e, KEY_QUESTIONHINT); // description child value
}
