Web automation with twill

[qwweeeit at yahoo.it]

Hi all,
this post is a kind of continuation of my
"Expanding Python as a macro language"

Among the replies gmi... at gmail.com directed me to:
http://www.idyll.org/~t/www-tools/twill.html
(a python tool with a language to script "web commands")

I applied twill to a problem I had solved "by hand"
clicking 220 times on a button and saving the data sent
by the server (it is an "asp" file).

In this case web automation is needed!
I need the help of some expert or of the author (Titus Brown).

The asp file is (I am Italian!):
http://www.scienzemfn.unito.it/job_placement/studenti/Elenco_completo.asp
If you open it you see a button with "Page Down" that must be clicked
to get all the data in chunks.

I used twill (vers. 0.7.3) in interactive mode:
twill-sh -u
http://www.scienzemfn.unito.it/job_placement/studenti/Elenco_completo.asp
or twill-sh ... and then >>go webaddress

With "show" you see the the list of the html file representing
the 1st chunk (page 1 of 223)
With "showforms" you obtain:
Form #1
## __Name______ __Type___ __ID________ __Value___
   PageNo       hidden    (None)       1
1  Mv           submit    (None)       Page Down
Form #2
## __Name______ __Type___ __ID________ __Value___
   PageNo       hidden    (None)       1
   None         button    (None)       None
1  Mv           submit    (None)       Page Down

Using twill you can access the following page and save it by:
>> fv 1 "Mv" "Page down"
>> submit
>> save_html file_name

with >> showforms you obtain:
Form #1
## __Name______ __Type___ __ID________ __Value___
   PageNo       hidden    (None)       2
1  Mv           submit    (None)       Page Down
2  Mv           submit    (None)       Page Up
Form #2
## __Name______ __Type___ __ID________ __Value___
   PageNo       hidden    (None)       2
   None         button    (None)       None
1  Mv           submit    (None)       Page Down
2  Mv           submit    (None)       Page Up
Beeing the second page a further button shows up ("Page Up")

But now I get lost... I am not able to load the 3rd page...
In fact repeating the aforementioned sequence:
>> fv ... + submit
the button activated by the "submit" command is "Page Up"!

Any help?

IMHO, twill is great ...expecially if we can make it work
outside from its first use (automatic web testing).
I must also say that it can be called as a module...

Bye.
