Wiremock standalone - Fetching values from request xml for a mock Soap service

Question

I've been trying to create a stub system for a SOAP service using wiremock standalone. I've got the response.xml s ready and I'm required to return them based on an id value in the SOAP request xml. For example, Soap Request:

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <AddressType>
            <addressId>Q1004DB</addressId>
        </AddressType>
    </soap:Body>
</soap:Envelope>

As I mentioned before, I have response xmls set for each of the address Ids. In this case, I've got a response xml named Q1004DB.xml which should be returned as response of this request. So I'm trying to figure out a logic to be put in place which will enable me to do this.

It would be great if someone can help me with how I can implement a logic in wiremock standalone where I can return a response based on the values in the input request xml. Thanks in advance !

As a first step, I tried returning the addressId as the response. I followed a couple of answers from StackOverflow and saw this format but this doesn't seem to work. Can someone please tell what might be wrong here ?

{
  "request": {
    "url": "/ws/AddressSoapService",
    "method": "POST"
  },
  "response": {
    "body": "{{$.addressType.addressId}}",
    "headers": {
      "Server": "Microsoft-IIS/8.0",
      "Connection": "Keep-Alive",

      "Content-Type": "application/soap+xml; charset=utf-8"
    }
  }
}
