Java - 使用 XSD 校验 XML

 

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);        
    }
    
}
