  Looks something like this

http://tutorials.jenkov.com/java-xml/stax-xmleventwriter.html

If you want a String at the end, just use a StringWriter as you Writer. 
If you really want a StringBuilder rather than a String, you may have to 
write your own Writer, but that seems easy enough.

(Saxon 9.3 adds a StAX writing interface to allow you to write 
programmatically to the Saxon serializer, with full control of all the 
serialization parameters, but that's not released yet).
