Xsd文件验证xml的java实现

xsd文件验证xml的java实现

今天在修改数据交换平台时候，看见其中使用此技术

import java.io.File; import java.io.IOException;

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 ValidateXML {

/**
*
*/
public ValidateXML(){

}

public boolean Validatexml(String xsdpath,String xmlpath) throws SAXException,IOException{
//建立schema工厂
SchemaFactory schemaFactory=SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
//建立验证文档文件对象，利用此文件对象所封装的文件进行schema验证
File schemaFile=new File(xsdpath);
//利用schema工厂，接收验证文档文件对象生成Schema对象
Schema schema=schemaFactory.newSchema(schemaFile);
//通过Schema产生针对于此Schema的验证器，利用schenaFile进行验证
Validator validator=schema.newValidator();
//得到验证的数据源
Source source=new StreamSource(xmlpath);
//开始验证，成功输出success!!!，失败输出fail
try{

validator.validate(source);

}catch(Exception ex){

ex.printStackTrace();

}
return true;
}

}

XML文件

<?xml version="1.0" encoding="gbk"?> <Test id="F2009045002100N03030100"> <NewData > <deviceTypeId>16135</deviceTypeId> <iconName>变电站.gif</iconName> </NewData> </Test>

验证XSD文件
