I'm still a bit of a nube with ruby but I have been working with this 
library a little bit.
Using your example response:

def check_and_change
res=@parsed_response
name='rub'
itemtype='Book'

# if the name in your results does not equal 'rub' changes the value to 
'rub'
if res['name'] != name
  res['name']=name
end

#if the item type is 'Book' puts 'Win'

if res['number']['item']['itemcontent']['itemcatagory']['@itemtype']== 
itemtype
puts 'Win'
end

#If there are multiple 'item' records
assuming it looks like this:
> @parsed_response => {"name" => "ruby", "number" => {"item"=>{"@no"=>"1",
> .......}},{"item" => {"@no" = >"2", ....}},{"item" => {"@no" = >"3",
> ....}}}

if 
res['number'].first['item']['itemcontent']['itemcatagory']['@itemtype']== 
itemtype
puts 'first Win'
end
if 
res['number'].last['item']['itemcontent']['itemcatagory']['@itemtype']== 
itemtype
puts 'last Win'
end

Hope that makes sense and helps
