Sorry, maybe I used the wrong term...
Here an example:
public class CustomTransformer extends AbstractSAXTransformer {
protected Properties format;
public SOAPTransformer() {
//format = XMLUtils.createPropertiesForXML( true );
format = new Properties();
format.put( OutputKeys.METHOD, "xml" );
format.put( OutputKeys.OMIT_XML_DECLARATION, "yes" );
}
public void setup( SourceResolver sourceResolver,
Map map,
String str,
Parameters parameters )
throws ProcessingException, SAXException, IOException {
// get some parameters here...
}
public void startDocument() throws SAXException {
this.startSerializedXMLRecording( format );
}
public void endDocument() throws SAXException {
try {
String message = this.endSerializedXMLRecording();
execute ( message );
} catch ( ProcessingException pe ) {
throw new SAXException( pe.getMessage() );
}
}
protected void execute ( String message )
throws ProcessingException, SAXException {
try {
// I use the XMLReader just to see what is hapenning...
// This method would rather do something with the XML message, maybe send it
// to a remote server and return back the response to the pipeline
XMLReader xmlReader = XMLReaderFactory.createXMLReader();
xmlReader.setFeature(
"http://xml.org/sax/features/namespaces";, true );
xmlReader.setFeature(
"http://xml.org/sax/features/namespace-prefixes";, false );
xmlReader.setContentHandler( this.contentHandler );
StringReader strRdr = new StringReader( message );
InputSource inSrc = new InputSource( strRdr );
xmlReader.parse( inSrc );
} catch ( Exception e ) {
throw new ProcessingException( e.getMessage() );
}
}
}
This gives me the entire XML file minus the XML Namespaces. So I got a
prefix not bound error when I execute it. Any ideas? What happends if I have
more than one namespace?
Thanks for your help.

Can you put an example? I don't fully understand your problem.
The XML file is already parsed after the generation phase. Parse = convert
text to SAX events.
