I've written a SGF grammar for the ANTLR parser generator 
(http://www.antlr.org). It can generate C++, Java (and C# code with 
minor modifications). I plan to put it on my web page today, so anyone 
can test it. Perhaps you can play with the ANTLR toolkit and think about 
a way to translate the internal AST to XML. I am also interested in this 
conversion. At the moment it parses correctly the test file in 
http://www.red-bean.com/sgf/examples/ff4_ex.sgf but the correctness of 
the grammar hasn't been through fully tested.
   Don't know if this is useful to you.
