Post REST message on Cloud API (using HTTPS post)

Hi Team,

We have a current process where we are querying an IO and taking that siebel message convert it to a SOAP message (XML Doc) format and post it to a Cloud API ( Cloud has provided a URL on which we post the message). This is currently a working process.

We are using EAI HTTP Transport, Post method to post the message on to the cloud.

Now due to recent changes, cloud team is expecting a REST format message to be posted rather than a SOAP message, Is there a simple way to convert the XML Hierarchy to REST format and post it. escript is not an option due to our architecture.
