Round II:
Here's my transformer code, (I know there's extra imports I don't need just yet): ----- package com.openweather.cocoon.transformation;
import org.apache.cocoon.transformation.AbstractSAXTransformer; import org.apache.cocoon.environment.SourceResolver; import org.apache.cocoon.ProcessingException; import org.apache.avalon.framework.parameters.Parameters; import org.apache.avalon.framework.logger.Logger;
import org.xml.sax.SAXException; import org.xml.sax.Attributes;
import java.util.Map; import java.io.IOException;
public class CAPDescriptionTransformer
extends AbstractSAXTransformer {protected String NAMESPACE = "http://www.incident.com/cap/1.0";; protected String DESCRIPTION = "description"; private String text = null;
public void startElement(String uri, String name, String raw, Attributes attr)
throws SAXException {super.startElement(uri, name, raw, attr);
if ( NAMESPACE.equals(uri) && DESCRIPTION.equals(name) ) {
this.text = null;
startTextRecording();
}
} public void endElement(String uri, String name, String raw, Attributes attr)
throws SAXException { if ( NAMESPACE.equals(uri) && DESCRIPTION.equals(name) ) {
// we found the element // get the text and process
this.text = endTextRecording();
// send the processed characters to the next pipeline component characters( process(this.text).toCharArray(), 0, text.length() ); }
// end the element
super.endElement(uri, name, raw);
} private String process(String text) {
System.out.println("inside process()");// @TODO: finish me
// arbitrarily process the text
System.out.println("leaving process before return():");
return text.toLowerCase();
}

}
}By using the LogTransformer before and after my transformer, it seems that once startRecording() is called, no events are sent to my tranformer. I would assume that calling endRecording() would turn that off, but that doesn't seem to be the case. Can anyone tell me where I'm going wrong? I notices the SourceWritingTransformer keeps a stack... am I going to have to keep track of the elements I see once I've started recording?
