Mock response with repetitions

I'm trying to do mock response based on the request. With a request like that:

<soapenv:Body>
  <con:person>
     <person>
        <name>John</name>
        <age>18</age>
     </person>
  </con:person>
</soapenv:Body>

and a reponse like that

<soapenv:Body>
  <con:result>
     <person>
        <name>?</name>
        <age>?</age>
        <country>?</country>
        <city>?</city>
     </person>
  </con:result>
</soapenv:Body>

I can use elements from the request to take what i want in database and create the response. But when i have a request with many person like that

<soapenv:Body>
  <con:person>
     <person>
        <name>John</name>
        <age>18</age>
     </person>
     <person>
        <name>Doe</name>
        <age>50</age>
     </person>
  </con:person>
</soapenv:Body>

I don't know how i can take all data from the request and how i can use them to create a response like that:

<soapenv:Body>
  <con:result>
     <person>
        <name>John</name>
        <age>18</age>
        <country>France</country>
        <city>Paris</city>
     </person>
     <person>
        <name>Doe</name>
        <age>50</age>
        <country>Spain</country>
        <city>Madrid</city>
     </person>
  </con:result>
</soapenv:Body>

With the same number of person in the request and in the response.

I hope i was clear and i thank you for your answers.
