I only hope that Rhino doesn't take our facetiousness as mean-spirited,
and that he will respond with an indication of where his content resides.

XSLT can be used turn SAX events into an XML-formatted stream, though I've
never seen that used as a way of composing XML. Hmm.

import org.xml.sax.ContentHandler;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.XMLFilterImpl;

import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.sax.SAXSource;
import javax.xml.transform.stream.StreamResult;
import java.io.IOException;

public class MakeXML
{
public static void main(String[] args) throws Exception
{
Transformer xf = TransformerFactory.newInstance().newTransformer();
xf.transform(
new SAXSource(new XMLEventGenerator(), null),
new StreamResult(System.out));
}

public static class XMLEventGenerator extends XMLFilterImpl
{
public void parse(String systemId) throws SAXException, IOException
{
generateEvents();
}

public void parse(InputSource input) throws SAXException,
IOException
{
generateEvents();
}

private void generateEvents() throws SAXException
{
ContentHandler ch = getContentHandler();
ch.startDocument();
ch.startElement(null, "start", "start", null);
ch.endElement(null, "start", "start");
ch.endDocument();
}
}
}

outputs :

<?xml version="1.0" encoding="UTF-8"?><start/>
