Hello Djoerd,
Thanks for the feedback. One reason (that i can see) to do it from stdin is so that compression can be used (without having to be aware of it), for example:
bzcat collection.tar.bz2 | mclient -lxq -C collection
But I do agree with you that it would be useful to have an XQuery function too, as not everyone is using the mclient interface.
Greetings, Wouter
Oh yes, and i forgot cvs does not unify its diff by default... hereby the unified diff for the clients package. (sooner or later I will learn to do things right the first time :)

Hi Wouter,
Sounds very useful to me! Why is it not simply changed in pf:add-doc(), or put in a new function pf:add-archive()?
Best, Djoerd.

Hello devs,
Roberto and I yesterday discussed that it would be useful to be able to load (compressed) XML collections directly into MonetDB/XQuery. The attached diff provides a new feature for loading multiple XML docs directly from tar files. Usage: "mclient -lxq -C <colname>" and pass a tarfile via stdin, see example below.
My question: is this useful enough to make it into MonetDB? And if so, is the current syntax appropriate. Comments are appreciated.
Greetings, Wouter
