Use of CDuce (was: Re: [Demexp-dev] CDuce binding in Makefile.)

Hello Serge,

me:

Ok. So if I understand correctly:

 - [d]: in the xml file "demexp_base.xml" loaded in variable d;

 - for all String nodes under the tree path <participant_base> -->
   <participant kind="individual"> --> <login> ("_" means match-all?);

 - return the string node element s.

Have I understood?

So, if I'm correct, one can load an arbitrary part of the XML
document? And I suppose we can also modify this arbitrary part
(e.g. rewrite a given login)?

I also suppose that CDuce .cd files can be parameterized by ocaml
variable so, once compiled into ocaml, we could create ad-hoc functions
to manipulate our XML database?

Yours,
d.
