想读写XML？想操作DOM？

不需要JDOM、Dom4j……，仅凭JDK就可以搞定！

据说jdk1.4就行了。以下在jdk5中测试通过：

 
 import java.io.File;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.Result;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
public class Dom2Xml {
    public static void main(String[] args) throws ParserConfigurationException,
            SAXException, IOException, TransformerException {
        // 解析XML 
        DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = builderFactory.newDocumentBuilder();
        String uri = "http://blog.youkuaiyun.com/CaiKanXP/Rss.aspx";
        Document document = builder.parse(uri);
        // 生成XML 
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        Source source = new DOMSource(document);
        String pathname = "dom2xml.xml";
        File file = new File(pathname);
        Result result = new StreamResult(file);
        transformer.transform(source, result);
    }
}
