Sending raw XML with Savon 2

I am trying to use Savon to send requests to a web service. The service I consume requires nested namespaces, and I still haven't figured out how to provide them on demand.

I tried to process the request manually (using nokogiri, actually) and send the resulting xml:

client.call(:some_op, :message=>{:"op"=>"<elem/>"})

But savon avoids the line and sends &lt;elem/&gt;

How can I send raw xml without escaping?

The call should look like this:

 client.call(:some_op, xml: "<elem />")

Or, if you just want to install one or more namespaces, create the client as follows (without WSDL):

 client = Savon.client( :endpoint => 'http://www.example.com', :namespace => 'urn:core.example.com', :namespaces => { 'ns1' => 'http://v1.example.com', 'ns2' => 'http://v2.example.com' }, :log => true, :log_level => :debug, :pretty_print_xml => true )

Namespaces are Hash parameters.

It seems that Savon internally uses Gem Gyoku to convert Ruby hashes to XML, and Gyoku will not escape hash keys ending with exclamation marks, as per the documentation: https://github.com/savonrb/gyoku#special-characters

Thus, this code works to get the raw XML in the request, while at the same time using Savon to generate the XML envelope:

client.call(:some_op, :message=>{:"op!"=>"<elem/>"})
