And here's mine.  Only an example for proof of concept.

query = ARGV.shift or raise ArgumentError

require 'soap/marshal'
class MyXMLHandler < SOAP::EncodingStyle::SOAPHandler
   Namespace = 'urn:myxmlhandler'
   add_handler
   def decode_parent(parent, node)
     super if parent.node	# ignore absence of SOAP envelop things.
   end
end

require 'http-access2'
url = 'http://api.search.yahoo.com/NewsSearchService/V1/newsSearch'
param = {
   'appid' => '!!! set_your_appid_here !!!',
   'query' => query,
   'results' => 3,
   'language' => 'en',
   'results_sort' => 'rank'
}
result = HTTPAccess2.get_content(url, param)

opt = {:default_encodingstyle => 'urn:myxmlhandler'}
soap = SOAP::Processor.unmarshal(result, opt)

SOAP::Mapping.soap2obj(soap).Result.each do |result|
   next unless result["Thumbnail"]
   p result.Thumbnail.Url
end
