Currently I'm using [Savon](http://savon.rubiii.com) to work with WebService in ruby.
It works pretty well but I have difficulty to pass parameter for
argument of SOAP array type. Following code doesn't work properly:

```
ids = [0,1,2]
client.do_get_items { |soap| soap.body = {
    'item-list' => ids
}

```

I would appreciate if you can solve my problem or propose an alternative
library for ruby&soap
