The REPLACE command [1,2] will remove existing versions of a document. Christian [1] http://docs.basex.org/wiki/Commands#REPLACE [2] http://docs.basex.org/wiki/Database_Module#db:replace

Hi guys, Why am I able to add/store several XML with the same path?

I'm sorry I'm not sure what you want to know. Could you give more details? Christian

You mean that BaseX should not allow adding multiple resources with the same path? There is indeed one open GitHub issue for that: https://github.com/BaseXdb/basex/issues/429 One advantage of the current solution is that new documents can be added extremely fast – exactly because of the missing duplicate check. The main challenge of resolving issue 429 will be to ensure that performance won't suffer too much.

Shouldn't have a 'constraint' to avoid replacing a file? so if the path exists you can use REPLACE but not ADD or STORE cmd 2012/6/6 Christian Grün <christian.gruen at gmail.com>
