如何从SOAP数组响应中获取数据的特定部分？

Question

我刚开始使用红宝石，花了一整个上午在这上面打我的头。我以数组的形式从SOAP服务器获得响应(如下所示)，并使用这段代码尝试获取活动调用(78523)的callID：

activecall = driver.GetActiveCalls("clientHandle"=>handle,
            "lineID"=>line["OpenLineResult"].lineID,
            "getCallParties"=>1,
            "getCallProperties"=>1)

print "  call ID = ", activecall["GetActiveCallsResult"].callID,
  "\n  Line Type = ", activecall["GetActiveCallsResult"].calledID, "\n\n"

我知道错误：

 undefined method `callID' for #<SOAP::Mapping::Object:0x..fdb79d636> (NoMethodError)

知道我做错了什么，以及如何提取这些数据吗？

从红宝石端处理SOAP，它将重新注释以使用http://savonrb.com/version2。但不管怎么说，你有没有尝试过

activecall["GetActiveCallsResult"]["ShoreTelCallStateInfo"]

我认为这些MappingObjects提供了对切尔德节点的访问，就像使用密钥访问散列一样，在本例中，xml模式的限定名参见http://ruby-doc.org/stdlib-1.8.7/libdoc/soap/rdoc/SOAP/Mapping/Object.html。
