[Ruby] Newby XML question

John,

They'll likely be sending this via a http post on a param.  You probably
need to configure this on their end so give them a url to your controller  (
http://mysite.com/webservices/index) and you'll need to know the param name
(which you can always figure out via "render :text => params.to_yaml" which
will show you all params sent.  When you know the param name get the xml
value via a "xml = params[:some_param_name]"

Example:

class WebservicesController < ApplicationController

  def index
     render :text => params.to_yaml
     # or
     xml = params[:some_param_name]
     #xml no contains the xml text which you can parse
  end

end

You might want to look into rest examples..  which I think is the "right"
way to do this in Rails.
