package com.huey.dream.utils;



import java.io.IOException;

import java.io.InputStream;



import javax.xml.transform.Source;

import javax.xml.transform.stream.StreamSource;

import javax.xml.validation.Schema;

import javax.xml.validation.SchemaFactory;

import javax.xml.validation.Validator;



import org.xml.sax.SAXException;



public class XSDValidator {

    

    static public void validate(InputStream xsdStream, InputStream xmlStream) throws SAXException, IOException {

        SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");                

        Source xsdSource = new StreamSource(xsdStream);

        Schema schema = schemaFactory.newSchema(xsdSource);

        

        Source xmlSource = new StreamSource(xmlStream);

        

        Validator validator = schema.newValidator();

        validator.validate(xmlSource);        

    }
