Seems to be a simple XML structure as you said.  Here is an example.

# To run the following code, you need to get the latest
# soap4r module from SVN repository.

Regards,
// NaHi

## preparing

t = Time.now
starter = Time.local(t.year,t.mon, t.day) + (24 *3600)
ender = starter + 7 * 24 *3600
lattitude = 39.0
longitude = -77.0

## accessing through dynamically generated driver

require 'soap/wsdlDriver'

params = {:maxt => false, :mint => false, :temp => true, :dew => true,
  :pop12 => false, :qpf => false, :sky => false, :snow => false,
  :wspd => false, :wdir => false, :wx => false, :waveh => false,
  :icons => false}

wsdl = "http://weather.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl"
drv = SOAP::WSDLDriverFactory.new(wsdl).create_rpc_driver
drv.wiredump_dev = STDOUT if $DEBUG
dwml = drv.NDFDgen(lattitude, longitude, 'time-series', starter, ender,
params)
puts dwml

soap = SOAP::Processor.unmarshal(dwml)
data = SOAP::Mapping.soap2obj(soap["data"])

data.parameters.temperature.each do |temp|
  p temp.name
  p temp.value
end

p data["time-layout"]["start-valid-time"]
