Send XML in message service bus and parse it in logic app

As I am a beginner on azue, I would like to know the procedure to follow for the following process: sending an xml with a service bus message and receiving and parse it with logic app. Thanks

Solution

I have used 2 logic apps in this case where 1 sends an XML message through the service bus and the other receives it.

The flow of Logic App - 1 (Sending XML message to Service bus)

The flow of Logic App - 2 (Receiving XML message from Service bus and parsing it)

You can convert XML to JSON and then use Parse_JSON to parse it.

RESULT:
