Get specific error message in xml validation with xsd

[shiva kumar g]

Hi,

I am using XSD schema to validate the XML String. I am able to validate the XML against XSD schema, but while validating the XML i am getting the SAXException messages as below

cvc-maxExclusive-valid: Value '23123132321323123123213' is not facet-valid with respect to maxExclusive '999999999999999' for type 'MerchantTrackIdType'.
cvc-type.3.1.3: The value '23123132321323123123213' of element 'MerchantTrackId' is not valid.

Here i am implementing the ErrorHandler(MyErrorHandler) class and getting the above exception messages. But to give exact error response to out i wish to get the only
The value '23123132321323123123213' of element 'MerchantTrackId' is not valid.

public static String validateXml(Schema schema, Document document) {
	try {
		// creating a Validator instance with loading xml schema "http://www.w3.org/2001/XMLSchema"
		Validator validator = schema.newValidator();
		validator.setErrorHandler(new MyErrorHandler());
		// validating the document(Parsed xml document) against the schema
		validator.validate(new DOMSource(document));
		return "Validation Success";
	} catch (Exception e) {
		e.printStackTrace();
		return e.getLocalizedMessage();
	}
}

 class MyErrorHandler implements ErrorHandler {
    public void fatalError( SAXParseException e )
       throws SAXException {
      System.out.println(e.toString());
      throw e;
    }
    public void error( SAXParseException e ) throws SAXException {
      System.out.println(e.getMessage());
    }
    public void warning( SAXParseException e ) throws SAXException {
      System.out.println(e.toString());
    }
}

I googled out for getting the only cvc-type message from SAXException, Please help me in this regards if you found any solution.

Thanks in advance.

The bare minimal to establish the "localized message" from within the ErrorHandler can be this (or some variants you can think of).

//etc etc
import java.util.regex.*;
class MyErrorHandler implements ErrorHandler {   
    Pattern p=Pattern.compile("\\s*:\\s*");
    public void fatalError( SAXParseException e )   
       throws SAXException {   
      System.out.println(e.toString());   
      throw e;   
    }   
    public void error( SAXParseException e ) throws SAXException {   
      //System.out.println(e.getMessage());   
      System.out.println(p.split(e.getMessage())[1]);
    }   
    public void warning( SAXParseException e ) throws SAXException {   
      System.out.println(e.toString());   
    }   
}  

You can conceive a scheme to collect and to store the messages from within the handler and construct a method (called getLocalizedMessage() or whatever) to return the complete messages to the caller. It is up to you to do.
