jdom实现schema验证xml文件是否合法
导入jdom1.1版
http://www.jdom.org/dist/binary/
import java.io.FileReader;
import org.jdom.Document;
import org.jdom.input.SAXBuilder;
public class XMLValidate {
public void validate(String xml, String schema) {
try {
SAXBuilder builder = new SAXBuilder(true);
//指定约束方式为XML schema
builder.setFeature("http://apache.org/xml/features/validation/schema",true);
//导入schema文件
builder.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",schema);
Document doc = builder.build(new FileReader(xml));
System.out.println("恭喜您，验证通过！！！");
}catch(Exception e) {
System.out.println("验证失败:"+e);
}
}
public static void main(String args[]) {
new XMLValidate().validate("e:\\a.xml","e:\\b.xsd");
}
}
老版本需要用到Xerces
参见http://www.jdom.org/docs/faq.html#a0360
How do I validate against a schema when using JDOM?
JDOM doesn't have it's own parser; it uses standard parsers like Xerces to do the heavy lifting. If you want schema validation make sure you choose a parser that supports schemas. Xerces 2 is a good choice (get it from http://xml.apache.org). You also need to use code JDOM Beta 8 or later.
To specify the parser JDOM uses, you can either configure JAXP appropriately (since JDOM uses JAXP if it's available, see the end of this entry for details) or you can explicitly pass the name of the parser to the SAXBuilder constructor. For Xerces 2 the parser class is org.apache.xerces.parsers.SAXParser. You must also enable parser validation by passing "true" when creating a SAXBuilder.
SAXBuilder builder =
new SAXBuilder("org.apache.xerces.parsers.SAXParser", true);
Next, you tell the parser (Xerces) you want to validate against a schema (or schemas), and you pass the parser information about those schema. Different parsers do this in different ways. In Xerces you do this by

XStream使用
XStream是一个Java对象和XML相互转换的工具，很好很强大。提供了所有的基础类型、数组、集合等类型直接转换的支持。因此XML常用于数据交换、对象序列化（这种序列化和Java对象的序列化技术有着本质的区别）。
XStream中的核心类就是XStream类，一般来说，熟悉这个类基本就够用了，如果你用的更多，估计是� ......
