1) Most DOM implementations come with a serializer which will render a
document (or a subtree) as XML syntax. Check the documentation for yours.
2) Yes, Xalan can be used as a serializer. Use the TrAX APIs, pass us a
DOMSource which has been set to point to your Node, and pass us a
StreamResult to tell us where to write the output. The "default identity
transformation" should copy data through. HOWEVER: Note that Xalan assumes
all the DOM nodes are DOM Level 2 nodes (namespace-aware); if yours isn't
we may not process it correctly. Also note that the default identity
tranformation has some known weak points; you may be better off using an
explicit identity stylesheet, though that has its own limitations since
the XPath data model used in stylesheet processing does not preserve all
the details the DOM can represent.
