Hi,

Am using dom parser to parse XML document. Am getting the following error while executing the parser class.
"Element type FirstName is not declared".
Can one tell me what causes this problem?

//use document builder

File file = new File("mytext1.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(file);
doc.getDocumentElement().normalize();
System.out.println("Root element:-" + doc.getDocumentElement().getNodeName());
NodeList nodeLst = doc.getElementsByTagName("article");
f
System.out.println("--------Information of all Data-------");
log.debug("The Information of all the data is ");
for (int s = 0; s < nodeLst.getLength(); s++)
{
double sum=0.0;
Node fstNode = nodeLst.item(s);
if (fstNode.getNodeType() == Node.ELEMENT_NODE)
{
Element fstElmnt = (Element) fstNode;
NodeList fstNmElmntLst = fstElmnt.getElementsByTagName("title");
Element fstNmElmnt = (Element) fstNmElmntLst.item(0);
NodeList fstNm = fstNmElmnt.getChildNodes();
System.out.println("Bill Value : " + ((Node) fstNm.item(0)).getNodeValue());
log.debug("Bill Value : " + ((Node) fstNm.item(0)).getNodeValue());

String str=((Node) fstNm.item(0)).getNodeValue();
sum=sum+Double.valueOf(str.trim()).doubleValue();
//System.out.println("sum=" +sum);
