title: Is there a way to keep POSTed XML in tact in Ruby on Rails?
body: <p>I have a REST API in my Rails app that users will be posting XML to. I know that Rails (perhaps Rack in this case) converts the posted data to a params hash.</p>
  
  <p>I'm curious if there's a way to get Rails to not convert the XML to a params hash? Instead, I'd like to get the XML as a string. I'd rather not have Rails convert to a hash, and then use <code>to_xml</code> to convert it back to an xml string.</p>
