I would agree with these main choices. While you could
use data binding (xmlbeans, jaxb2), that seems bit
heavy-weight route since you don't care about type
mappings etc, so most of the work would be overhead.
SAX could of course be used, but I don't know of many
benefits over Stax for this use case.

In addition, if you decide to go Stax route (which may
make sense if you will eventually get bigger files --
1 M is still with about any solution, unless there's
lots of concurrent processing), you may want to check
out stax-utils project


since 'raw' Stax API is bit of PITA to use for many
tasks. For copying xml, using Event API it is quite

You could also try out StaxMate that I wrote
(http://woodstox.codehaus.org/StaxMate) which has
support for accessing xml content in streaming way,
but still allowing hierarchic traversal (in forward
Documentation is bit sparse, best way may be to read

(http://www.cowtowncoder.com/blog/blog.html). I should
write sample code for this particular use case though,
since it seems to be kind of recurring question
(usually on stax_builders list though), and it should
also be easy to add sub-tree pass-through copy
operation, so that this particular task would be just
couple of lines total.
