终于找到了基于SAX的XML生成方法了

原文: http://www.javazoom.net/services/newsletter/xmlgeneration.html

 

最佳方式:

 

JAXP + SAX + Serialization to servlet output stream : JDK 1.4 compliant - 
import java.io.*;
// SAX classes.
import org.xml.sax.*;
import org.xml.sax.helpers.*;
//JAXP 1.1
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.sax.*;
[...]
// PrintWriter from a Servlet
PrintWriter out = response.getWriter();
StreamResult streamResult = new StreamResult(out);
SAXTransformerFactory tf = (SAXTransformerFactory) SAXTransformerFactory.newInstance();
// SAX2.0 ContentHandler.
TransformerHandler hd = tf.newTransformerHandler();
Transformer serializer = hd.getTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING,"ISO-8859-1");
serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"users.dtd");
serializer.setOutputProperty(OutputKeys.INDENT,"yes");
hd.setResult(streamResult);
hd.startDocument();
AttributesImpl atts = new AttributesImpl();
// USERS tag.
hd.startElement("","","USERS",atts);
// USER tags.
String[] id = {"PWD122","MX787","A4Q45"};
String[] type = {"customer","manager","employee"};
String[] desc = {"Tim@Home","Jack&Moud","John D'oé"};
for (int i=0;i<id.length;i++)
{
  atts.clear();
  atts.addAttribute("","","ID","CDATA",id[i]);
  atts.addAttribute("","","TYPE","CDATA",type[i]);
  hd.startElement("","","USER",atts);
  hd.characters(desc[i].toCharArray(),0,desc[i].length());
  hd.endElement("","","USER");
}
hd.endElement("","","USERS");
hd.endDocument();
