[oXygen-user] Large XML file

[Syd Bauman]

Please don't take me wrong (as this is my 2nd post on this thread
recommending you check out a non-oXygen solution): I really really
like oXygen a lot, and use it very frequently. But it strikes me that
this task of yours

at least on very large files, is the kind of task for which XML
databases like eXist exist.

Note that 
a) I am *not* much of an eXist user (yet), so can't give you details
   on what to do, and
b) at least in the more expensive editions, oXygen provides a hook
   into eXist.
