com.oroad.stxx.transform
Class DOMWriteTransformer

java.lang.Object
  com.oroad.stxx.transform.AbstractSAXTransformer
      com.oroad.stxx.transform.DOMWriteTransformer

All Implemented Interfaces:

Transformer

public class DOMWriteTransformer

extends AbstractSAXTransformer

This transformer creates the usual xml from the request then saves it as a DOM node in either the request, session, or servlet context attributes. One possible use would be to use JSTL's XML tags to manipulate stxx-created XML by forwarding the request to a JSP using the "path" attribute.
