Hello Pablo and William,

Pablo: i did the command you said me, and i'm on the good way. One problem is
that i think that i don't have all the archives available on the website.

Whatever, it is better than my 50go download try 1 week ago...

William: to explain, my exact aim is to have a total picture of a market at
time t. This picture is made with statistics in the past and recent
qualitative data (interview, blog, etc.). To obtain datas, i selected about
ten websites wich should be quite representative.

I need to organize all this datas in tables to use it with SPSS Modeler and do
my modelistation of predictive statistics and probability of events.

After that, I can apply my modelisation to the futur and see how it is
performant.

I totaly open to all the ones who have ideas to obtain and organize these
datas availables on website.
