Hi Ron,

Adding another opinion the board (I meant to write this already on Saturday) ;-)

I don’t think there is much to optimize w.r.t. to the XQuery update solution, as your whole database will be held in memory during the update…

YET: if you do not care for the namespaces you could still strip them when creating your database:

```

db:create(

'mydb-no-ns',

'<xml xmlns="foo"><_></_></xml>',

'mydoc2.xml',

map {"stripns": "yes"}

)```

http://docs.basex.org/wiki/Database_Module#db:create

=> • parsing options will only impact string input (URIs, XML strings), because nodes have already been parsed.

Maybe this helps, I am not sure if someone already mentioned it!

Best

Michael

I can go with the default namespace declaration so no followup is needed, unless you are curious and have the time to investigate.
