Writing transformer

[simo kauranen <sl...@yahoo.com>]

Hey you cocoon professionals!

I wrote the transformer below. It does nothing except
creates an empty temp.xml-file. Why it does not
respond to sax events (from TraxTransformer)?
Appreciate all advice.

package org.apache.cocoon.transformation;


public class StoreTransformer extends
AbstractSAXTransformer {


	private String storeKey = null;
	
	private String filePath = "C:\\Program Files\\Apache
Group\\Tomcat 4.1\\webapps\\cocoon\\RF\\store\\";

	private PrintWriter out = null;


	public void configure(Configuration conf) throws
ConfigurationException {

		super.configure(conf);

        	if (conf != null) {
            		/*Configuration child;

			this.storeKey =
conf.getChild("map:parameter").getAttribute("value");

			*/

			filePath += "temp.xml";
			
			try {this.out = new PrintWriter(new
FileOutputStream(filePath), true);}
			catch(IOException e) {throw new
ConfigurationException("I/O Exception " + e);}     
		}

	}


	public void startDocument() throws SAXException {

            	emit("<?xml version=\"1.0\"
encoding=\"ISO-8859-1\"?>"); 
     	}


	public void characters(char buf[], int offset, int
len) throws SAXException {

            	String s = new String(buf, offset, len);
            	if (textBuffer == null) {
              		textBuffer = new StringBuffer(s);
            	} else {
              		textBuffer.append(s);
            	}
    	}	

	public void startElement(String namespaceURI, String
sName, String qName, Attributes attrs)
          	throws SAXException
       	{
		String eName = sName; // element name
            	if ("".equals(eName)) eName = qName; //
not namespaceAware
            	emit("<"+eName);
            	if (attrs != null) {
              		for (int i = 0; i < attrs.getLength();
i++) {
                		String aName =
attrs.getLocalName(i); // Attr name
                		if ("".equals(aName)) aName =
attrs.getQName(i);
                		emit(" ");
                	
emit(aName+"=\""+attrs.getValue(i)+"\"");
              		}
            	}
            	emit(">");
        }
           
        public void endElement(String namespaceURI,
String sName, String qName)
          	throws SAXException
      	{
        
		String eName = sName; // element name
            	if ("".equals(eName)) eName = qName; //
not namespaceAware
            	emit("<"+eName+">");            
       	}

	private void emit(String s) throws SAXException
{this.out.write(s);}

}
