+ |                              DESCRIPTION                                   |
+ I'm using programatically generated SAX input to Xalan. Xalan doesn't
+ seem to work properly when the qName paramterer to the ContentHandler
+ methods is the empty string. I think that Xalan should work properly
+ even when the qName is not given.
+ 
+ 
+ Here is a test program and a stylesheet:
+ 
+ 
+ // DirTest.java
+ 
+ 
+ import java.io.*;
+ 
+ 
+ import org.xml.sax.*;
+ import org.xml.sax.helpers.AttributesImpl;

+ 
+ import javax.xml.transform.*;
+ import javax.xml.transform.Source;
+ import javax.xml.transform.sax.*;
+ import javax.xml.transform.stream.StreamSource;
+ 
+ 
+ import org.apache.xml.serialize.*;
+ 
+ 
+ public class DirTest
+ {
+ public static void main(String[] args) throws Exception
+ {
+ if (args.length < 3)
+ {
+ System.out.println("Syntax: DirTest <input_dir> <stylesheet> <output>");
+ return;
+ }
+ 
+ 
+ String inDir = args[0];
+ String xslFile = args[1];
+ String outFile = args[2];
+ 
+ 
+ TransformerFactory tf = TransformerFactory.newInstance();
+ if (!(tf.getFeature(SAXTransformerFactory.FEATURE)
+ && tf.getFeature(SAXResult.FEATURE)
+ && tf.getFeature(StreamSource.FEATURE)))
+ {
+ System.out.println("The transformer factory "
+ + tf.getClass().getName() + " doesn't support SAX");
+ return;
+ }
+ SAXTransformerFactory tfactory = (SAXTransformerFactory)tf;
+ 
+ 
+ System.out.println("Read stylesheet " + xslFile);
+ 
+ 
+ Templates stylesheet = tfactory.newTemplates(new StreamSource(xslFile));
+ 
+ 
+ System.out.println("Transforming " + inDir + " to " + outFile);
+ 
+ 
+ XMLSerializer ser = new XMLSerializer(
+ new FileOutputStream(outFile), new OutputFormat());
+ 
+ 
+ TransformerHandler th = tfactory.newTransformerHandler(stylesheet);
+ th.setResult(new SAXResult(ser.asContentHandler()));
+ 
+ 
+ generateDirListing(new File(inDir), th);
+ 
+ 
+ System.out.println("Finished");
+ }
+ 
+ 
+ static void generateDirListing(File dir, ContentHandler sax)
+ throws SAXException
+ {
+ String[] files = dir.list();
+ 
+ 
+ sax.startDocument();
+ 
+ 
+ sax.startElement("", "dirlist", "", new AttributesImpl());
+ // sax.startElement("", "dirlist", "dirlist", new AttributesImpl());
+ 
+ 
+ for (int i = 0; i < files.length; i++)
+ {
+ File file = new File(dir, files[i]);
+ 
+ 
+ AttributesImpl atts = new AttributesImpl();
+ atts.addAttribute("", "filename", "", "CDATA", files[i]);
+ // atts.addAttribute("", "filename", "filename", "CDATA", files[i]);
+ 
+ 
+ if (file.isFile())
+ {
+ sax.startElement("", "file", "", atts);
+ // sax.startElement("", "file", "file", atts);
+ sax.endElement("", "file", "");
+ // sax.endElement("", "file", "file");
+ }
+ else if (file.isDirectory())
+ {
+ sax.startElement("", "directory", "", atts);
+ // sax.startElement("", "directory", "directory", atts);
+ sax.endElement("", "directory", "");
+ // sax.endElement("", "directory", "directory");
+ }
+ else
+ ;
+ }
+ 
+ 
+ sax.endElement("", "dirlist", "");
+ // sax.endElement("", "dirlist", "dirlist");
