RE: [oXygen-user] Large XML file

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

(/Institution/Student/HUSID[.='999999999999']) 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.
