This is what I am trying till now

DocumentBuilderFactory dbc = DocumentBuilderFactory.newInstance();
DocumentBuilder dbuilder;
try {
dbuilder = dbc.newDocumentBuilder();
Document doc = dbuilder.parse(new InputSource(new StringReader(plan.getProvisions())));
NodeList nl = doc.getElementsByTagName("Item");
for(int i = 0 ; i < nl.getLength(); i++){
if(i == row){
Element e = (Element)nl.item(i);
description = e.getAttribute("name");
} catch (ParserConfigurationException e) {
} catch (SAXException e) {
} catch (IOException e) {
