Document xmlDomObject = parseXMLDocument();
Node rootNode = xmlDomObject.getDocumentElement();
Element userElement = xmlDomObject.createElementNS(null, "USER");
userElement.setAttribute("ID",newUserRecordID);
userElement.setAttribute("Name", userName);
// Create Child element for User Name.
Element userNameElement = xmlDomObject
.createElementNS(null, "UserName");
Node userNameElementNode = xmlDomObject.createTextNode(userName);
userNameElement.appendChild(userNameElementNode);
// Create Child element for User Name.
Element roleElement = xmlDomObject.createElementNS(null, "Role");
Node roleElementNode = xmlDomObject.createTextNode(Role);
roleElement.appendChild(roleElementNode);
userElement.appendChild(userNameElement);
userElement.appendChild(roleElement);
DocumentFragment documentFragment = xmlDomObject.createDocumentFragment();
