Exception in thread "main" org.xml.sax.SAXParseException:

Question

Hi everybody,
I had a code which is running good in the output till error comes,i want to remove that error in xml file and replace with blanck(or null value) by using string function.
It will be a great help if some body could modify my code .
import javax.xml.bind.Validator;
import javax.xml.parsers.*;
import org.xml.sax.SAXException;
import org.xml.sax.XMLReader;
import org.xml.sax.helpers.DefaultHandler;
import java.util.jar.Attributes;
import java.io.File;
class Reading extends DefaultHandler
public static void main(String args[])throws Exception
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
File file=new File("C://raj.xml");
sp.parse(file,new Reading());
/*XMLReader xmlr=sp.getXMLReader();
xmlr.setContentHandler(new Reading());
xmlr.parse("first.xml");*/
private Object args;
public void startElement(String uri,String localName,String qName,
Attributes attributes)
System.out.println(qName);
public void characters(char []ch,int start,int length)
String str=new String(ch,start,length);
System.out.print(str);
public void endElement(String uri,String localName,String qName)
System.out.println(qName);
// Get a validator from the schema.
//Validator validator = schema.newValidator();
/*String file;
try {
Object validator;
     Object source;
     ((Object) validator).validate(source);
System.out.println(file + " is valid.");
catch (SAXException ex) {
System.out.println(file + " is not valid because ");
System.out.println(ex.getMessage());
/* Object args;
          if (args.length != 1) {
System.err.println("Exception in thread "main" org.xml.sax.SAXParseException: The entity "content_ppov_1704781_1091806592456" was referenced, but not declared.");
System.exit(1);
//public boolean equalsIgnoreCase(String anotherString)
//String s="content_ppov_1704781_1091806592456";
//String s1="null";
//Object error = null;
//Stringreplace(content_ppov_1704781_1091806592456,null);
//return null;
//System.out.println("");
//private void Stringreplace(Object error, Object object) {
     // TODO Auto-generated method stub
/* Object internal;
     private String file;
     // Let's suppose that lines in the underlying input stream are known
// to be no greater than 80 characters long.
     // Emit an error message, and delete the resource:
               String msg = file+ "content_ppov_1704781_1091806592456";
               //void getServer().errlog(this, msg);
               delete();
                    private void delete() {
                         // TODO Auto-generated method stub
                    private void errlog(Reading reading, String msg2) {
                         // TODO Auto-generated method stub
and my raj.xml file is like this
<div>This is a data .</div>]]>
</TEXT>
</content>
&content_1234789; // this line of error is comming
</content>
thanks in advance.
The error message displaying on console is
Exception in thread "main" org.xml.sax.SAXParseException: The entity "content_ppov_1704781_1091806592456" was referenced, but not declared.

The error is in your XML input, not in your Java code. Probably the XML doesn't declare its encoding, so the parser assumes that it is encoded in UTF-8. And probably it contains some character (like an accented letter, for example) that is not part of the UTF-8 encoding. So contact the person who created the XML -- which is not well-formed XML, by the way -- and get them to fix it. It's possible that declaring the encoding as ISO8859-1 might work, but it might not. All depends on what the invalid character is.
