How can I route my proxy service to another 3 local proxy services in OSB

Let me explain my situation. I recieve via a queue an XML file which will affect three different tables using ODATA RESTful services.

My logical conclusion to simplify the ODATA schema (instead of doing a batch) is to redirect the XML into three local proxys with different XQuery transformations. Then these proxys will call out the Web Services to update the database.

Can anyone help me? Can I use a for-each loop within a route node or is there another way to do this?

There are 3 options to route a payload/request to multiple different services (local proxies in your case) -

1. Publish - Sends asyncronous request to end point. receives no response.
2. Service Call Out - sends syncronous request to end point.
3. Split Join - Sends multiple simultanous syncronous requests to multiple end points, then merges responses.

I believe using 3 Publish actions is most suitable for your use-case.
