You need to define the service as a document service when you want to
handle XML attribute.  Try the following.

	/	/	/

require 'soap/rpc/driver'

ns = 'urn:namespace'
soapaction = nil

driver = SOAP::RPC::Driver.new(nil, ns)
driver.add_document_method('get_account', soapaction,
  XSD::QName.new(ns, 'GetAccountRequest'),
  XSD::QName.new(ns, 'GetAccountResponse'))

driver.test_loopback_response << <<__XML__
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
  <env:Body>
    <GetAccountResponse xmlns:ns0="urn:namespace">
      <account name="user@example.com"
          id="770316d9-qwe4-38eu-s84h-2dfe3c6cc874">
        <a n="key1">value1</a>
        <a n="key2">value2</a>
        <a n="key3">value3</a>
      </account>
    </GetAccountResponse>
  </env:Body>
</env:Envelope>
__XML__
driver.wiredump_dev = STDOUT

ele = SOAP::SOAPString.new('user@example.com')
ele.elename = XSD::QName.new(nil, 'account')
ele.extraattr[XSD::QName.new(nil, 'by')] = 'name'
# !!! a wrapper element is needed for document service.
req = SOAP::SOAPElement.new(XSD::QName.new(ns, 'GetAccountRequest'))
req.add(ele)

get_account = driver.get_account(req)
map = {}
get_account.account.a.each do |value|
  map[value.xmlattr_n] = value
end
p map   # => {"key1"=>"value1", "key2"=>"value2", "key3"=>"value3"}

# Now you want to write WSDL, don't you? :-)

Please let me know if you succeeded to use it.  Users must be interested
in it.
