public class DataMapper {

public static List getFieldList(int viewType) throws IOException,
JDOMException {

SAXBuilder builder = new SAXBuilder();
Document doc =
builder.build("http://localhost/xml/mapping.xml");

XPath fieldPath =
XPath.newInstance("//field[ui-display=\"Value1\" or
ui-display=\"Value2\"]");
List fields = fieldPath.selectNodes(doc);

return fields;
