如何从ruby客户端解析SOAP响应？

Question

我正在学习Ruby,我编写了以下代码来了解如何使用SOAP服务:

require 'soap/wsdlDriver'
wsdl="http://www.abundanttech.com/webservices/deadoralive/deadoralive.wsdl"
service=SOAP::WSDLDriverFactory.new(wsdl).create_rpc_driver
weather=service.getTodaysBirthdays('1/26/2010')

我得到的回应是:

#<SOAP::Mapping::Object:0x80ac3714 
{http://www.abundanttech.com/webservices/deadoralive} getTodaysBirthdaysResult=#<SOAP::Mapping::Object:0x80ac34a8 
{http://www.w3.org/2001/XMLSchema}schema=#<SOAP::Mapping::Object:0x80ac3214

{}DeadOrAlive="Alive">]>>>>

我有困难的很大搞清楚如何分析并显示在一个不错的表返回的信息,或甚至只是如何通过记录回路,并已获得各元素(即全名,年龄等).我经历了整个去"getTodaysBirthdaysResult.methods - Object.new.methods",并一直工作到尝试找出如何访问的元素,但后来我到阵列和我迷路了.

任何可以提供的帮助将不胜感激.

如果你打算反正解析XML,你不妨跳过SOAP4R与去Handsoap.免责声明:我是Handsoap的作者之一.

一个示例实现:

# wsdl: http://www.abundanttech.com/webservices/deadoralive/deadoralive.wsdl
DEADORALIVE_SERVICE_ENDPOINT = {
  :uri => 'http://www.abundanttech.com/WebServices/DeadOrAlive/DeadOrAlive.asmx',
  :version => 1
}

class DeadoraliveService < Handsoap::Service
  endpoint DEADORALIVE_SERVICE_ENDPOINT
  def on_create_document(doc)
    # register namespaces for the request
    doc.alias 'tns', 'http://www.abundanttech.com/webservices/deadoralive'
  end

  def on_response_document(doc)
    # register namespaces for the response
    doc.add_namespace 'ns', 'http://www.abundanttech.com/webservices/deadoralive'
  end

  # public methods

  def get_todays_birthdays
    soap_action = 'http://www.abundanttech.com/webservices/deadoralive/getTodaysBirthdays'
    response = invoke('tns:getTodaysBirthdays', soap_action)
    (response/"//NewDataSet/Table").map do |table|
      {
        :full_name => (table/"FullName").to_s,
        :birth_date => Date.strptime((table/"BirthDate").to_s, "%m/%d/%Y"),
        :death_date => Date.strptime((table/"DeathDate").to_s, "%m/%d/%Y"),
        :age => (table/"Age").to_s.gsub(/^\(([\d]+)\)$/, '\1').to_i,
        :known_for => (table/"KnownFor").to_s,
        :alive? => (table/"DeadOrAlive").to_s == "Alive"
      }
    end
  end
end

用法:

DeadoraliveService.get_todays_birthdays
