OK, done. Is good... very good.
Yields expected results similar to the Perl-Libs for
such work; but it's soooo much better here, because it's
cleaner ( typesafety and clearer structure than the Perl-stuff :) ).
So, this is, what I have looked for. :)
Are there "opposite" tools, to out back the datastructure,
which will get here from html-parsing back into a html-file?
I think about reading a html-file, throwing out unnecessary
contents, adding interesting stuff, re-layouting the page
and create new pages, better for viewing as output.
(Often webpages are messy (called "good designed";-)) and
I only need two or three parts of it. Creating a pagelaout,
which matches my needs is intended here.)
Can this be done by the cgi-module?
Or is it part of the nethtml-lib?

OK, if I can rely on the ocamlnet's sub-libraries, then I may write
such a client based on it.

Well, I have done socket-programming .... in C. :)

Hmhhh... how can be sockets read like channels?
Sockets must be handled unbuffered... Unix.read and such
functions... hmhhh is this done by Stream-module or similar
things? (Or could it be done in this way?)

Yes. It's powerful (and wonderful:)).
With each more of impression of Ocaml's features (e.g.
module system) and such libraries, I see, that my interest
in perl and other languages fades away....
