Adding attributes to an input tag with Savon

Do you hate making soap requests? Yeah, I do too, but at least Savon eases the pain. Savon, in my opinion, is easily the best gem out there for making soap requests, but there was a hangup that I'd like to share. When trying to contact a wsdl, the wsdl kept returning an error that it was looking for an input tag with a specific attribute. The wsdl was looking for something like this...

<AnAction xmlns="http://apathtosomething.com" />

It took me a few minutes to figure out, but this is the result...

soap_client = Savon.client("http://pathtowsdl.com/a.svc?wsdl")

response = soap_client.request "AnAction" do
  http.headers["soapAction"] = "AnAction"
  soap.input = ["AnAction", {"xmlns" => "http://apathtosomething.com"}]
  soap.body = {
    "SomeAttribute" => "SomeValue"
  }
end

Which would give you something like this...

<env:Envelope>
  <env:Body>
    <AnAction xmlns="http://apathtosomething.com" />
  </env:Body>
</env:Envelope>

There you have it, if you need an attribute on the input tag, you know how to do it.
