Hi,

I wrote java code for xml validation against xsd file.In that if any error in xml it throws the exception.Instead of that i want that program to return result in string like what is the problem.

package com.xmlpack;
import java.io.File;
import java.io.IOException;
import javax.xml.XMLConstants;
import javax.xml.transform.Result;
import javax.xml.transform.Source;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.*;
import org.xml.sax.SAXException;
public class SampleXmlValidator  {
	public static void main(String args[]) throws SAXException, IOException {
		// Construct a StreamSource from a File.
		Source xmlFile = new StreamSource(new File(
				"D:/SampleXML/sample/src/com/xml/product.xml"));
		// SchemaFactory is a schema compiler. It reads external representations
		// of schemas and prepares them for validation.
		SchemaFactory schemaFactory = SchemaFactory
				.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
		// This object represents a set of constraints that can be checked/
		// enforced against an XML document.
		Schema schema = schemaFactory.newSchema(new File(
				"D:/SampleXML/sample/src/com/xsd/product.xsd"));
		// A processor that checks an XML document against Schema.
		Validator validator = schema.newValidator();
	
		try {
			validator.validate(xmlFile);
			System.out.println(xmlFile.getSystemId() + " is valid");
		} catch (SAXException e) {
			System.out.println(xmlFile.getSystemId() + " is NOT valid");
			System.out.println("Reason: " + e.getLocalizedMessage());
		}
	}
}

in google search i found that we can use validator.validate(Source,Result) method.
I want to know how to implement the method..
