JBPM流程定義校驗之java利用XSD校驗XML

???????? 上篇我們學習了在.net中怎樣利用XSD來驗證xml，今天我們來看一下在java中怎樣實現利用xsd來校驗xml！

import?java.io.*;
import?javax.xml.transform.Source;
import?javax.xml.transform.stream.StreamSource;
import?javax.xml.validation.*;

?????????SchemaFactory?factory?=?SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
?????????Schema?schema=null;
?????????//xml和xsd是獨立的文件，否則是內聯文件
?????????if(xsdPath!=null&&xsdPath!=""){
?????????????File?schemaLocation?=?new?File(xsdPath);
?????????????schema?=?factory.newSchema(schemaLocation);??
