  Not solvable. The only information retained from the presence of
the XML Declaration is the encoding or standalone status if it was present.
the standalone status is actually only kept during parsing. The encoding
is saved in doc->encoding if present.
  Moreover libxml2 document saving always generate the XML Declaration,
the only way to get around this is to save the docuement children
independantly and not use the main routine.
  You're doing textual manipulation, and libxml2 works at the structured
level. Very different usecases.
