Hi Gianfranco,
Have you updated the soap module ?
I haven't had enough web experience to comment on anything being
normal in this game ! ;-)
I spent most of yesterday evening with this, and, thanks to Hiroshi's
contribution, it works great !
I downloaded the latest tarball as per Hiroshi's instruction ,
unzipped it, (its a .tar.gz file, so I had some difficulty locating
the right tools for unzipping it in windows ... I used 7zip in the end).
Did a 'ruby install.rb' in the extracted directory, and VOILA! my script
worked!

I found one small problem for which I have a workaround.
It is because the Betfair xml defines a method called 'id'
-----------
a= status.result.eventTypeItems.eventType.collect do |market|
   [market.name,market.id]
end
-----------
Unfortunately this name clashes with Ruby's 'id' method as in Object.id
Ruby warns that Object.id is 'deprecated' and that you should use
Object.object_id instead. So the wrong value is returned from 
'market.id'.

I don't know how to get around this problem, other than substituting 
'id='
for 'mktid=' in the xml first, or extracting the data manually.
eg.,
status=soap.getAllEventTypes(:request=>apiRequestHeader)
a= status.result.eventTypeItems.eventType.collect do |s|
   b=s.inspect[2..-2].split("{}")[1..-1].collect {|x| eval(x)}
   [b[1],b[0]]
end
(ugly, eh?)

Anyway, it's all going in the right direction.
I will keep you posted on any further issues I find.

Cheers,
Tad
