如何从XML和XSLT样式表输出HTML文件

package xslt;

import javax.xml.parsers.*;
import org.w3c.dom.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
import java.io.*;


class XSLT {
    public static void main ( String argv[] ) throws Exception {
    File stylesheet = new File("xslt-example.xsl");
    File xmlfile  = new File("SigmodRecord.xml");
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    Document document = db.parse(xmlfile);
    StreamSource stylesource = new StreamSource(stylesheet);
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer = tf.newTransformer(stylesource);
    DOMSource source = new DOMSource(document);
    //The Html output is in out.html
    StreamResult result = new StreamResult("out.html");
    transformer.transform(source,result);
    }
}
