Take transaction id from response and pass in next request

Hi

Actually I am new to ReadyAPI. I have following scenario. Can anyone please help on this.

Purchase one package and cancel transaction using transaction ID.


1. Purchase request: I have to pass package id from parameterised file. because it will change

<?xml version="1.0" encoding="UTF-8"?>
<test">
      <purchase>
         <msisdn>447717777777</msisdn>
         <package-id>2PP_P001</package-id>
         <rating-attributes />
      </purchase>
   
</test>

Response
<transaction-id>566</transaction-id>

2. Take transaction ID from response and pass in Cancel transaction request

<test>
        <cancelTrans>
            <transaction-id>566</transaction-id>
        </cancelTrans>
        
</test>
