Re: Custom Transformer: attributes lost when serialized XML recording

I have a custom transformer that extends AbstractSaxTransformer for

calls.  It extracts a method call element from an input document and
sends this to
the remote service for processing.
My problem is that when I use the startSerializedXMLRecording() method
from
AbstractSaxTransformer to collect the method call fragment it records
elements
only and the namespace attribute on the top-level element is lost.
This isn't a problem with the generator that creates the input document
as I can
see the attributes if I serialize the document after generation.
Is there a configuration step that I'm missing?
 

I think you should maintain map of namespace declarations (by processing 
start/end namespace mapping event) and declare all namespaces when you 
start recording. Look around for code samples, I think there is 
something similar in other transformers.

public void startElement(String uri, String name, String raw, Attributes
attr)
throws SAXException {
if (name.equals(XMLRPC_REQUEST_ELEMENT)) {
    this.stack.push("end");
} else if (name.equals(XMLRPC_SERVICE_ELEMENT)){
           this.startTextRecording();     
} else if (name.equals(XMLRPC_METHOD_CALL_ELEMENT)) {

this.startSerializedXMLRecording(XMLUtils.defaultSerializeToXMLFormat(tr
ue));     
} else {
           super.startElement(uri, name, raw, attr);
       }
   }
