What about this little problem, assuming you're
|
||
|
|
interested in internet programming and keen to get
|
||
|
|
familiar with the Python XML module...? ;-)
|
||
|
|
|
||
|
|
Have fun,
|
||
|

Context:
|
||
|
|
|
||
|
|
The Altavista babelfish returns the following result
|
||
|
|
page (see appendix below) after issuing this request:
|
||
|
|
|
||
|
|
"translate 'water' from English to French"
|
||
|
|
|
||
|
|
on that WWW page:
|
||
|
|
|
||
|
|
http://babelfish.altavista.com
|
||
|
|
|
||
|
|
Some quick testing reveales that you can do the same
|
||
|
|
with just typing the following (wrapped) URL in your
|
||
|
|
browser:
|
||
|
|
|
||
|
|
http://babelfish.altavista.com/cgi-bin/translate?
|
||
|
|
doit=done&urltext=water&lp=en_fr
|
||
|
|
|
||
|
|
Exercise 1:
|
||
|
|
|
||
|
|
Write a program babelfish.py calling the Altavista
|
||
|
|
Babelfish over the WWW (using httplib, say) and parse
|
||
|
|
its HTML output using your favorite HTML/XML parser
|
||
|
|
(suggestion: use the XML module written by the Python
|
||
|
|
XML-SIG) in order to extract the result and print it
|
||
|
|
nicely in a terminal window like this:
|
||
|
|
|
||
|
|
darwin> python babelfish.py water en_fr
|
||
|
|
l'eau
|
||
|
|
darwin>
|
||
|
|
|
||
|
|
Exercise 2:
|
||
|
|
|
||
|
|
Improve your program by allowing multiple words to
|
||
|
|
be translated in a row, like this (you'll have to
|
||
|
|
send multiple requests as Babelfish will try to
|
||
|
|
treat your words as a sentence):
|
||
|
|
|
||
|
|
darwin> python babelfish.py spam eggs en_fr
|
||
|
|
spam
|
||
|
|
oeufs
|
||
|
|
darwin>
|
||
|
|
|
||
|
|
