Automation of testing a xml request

Please help me with one case. If we have a xml request like this

<soap:Envelope

xmlns:soap=“http://www.w3.org/2003/05/soap-envelope/

soap:encodingStyle=“http://www.w3.org/2003/05/soap-encoding”>

soap:Header

<roll>100</roll>

</soap:Header>

soap:Body

</soap:Body>
</soap:Envelope>

Can we submit request using different roll like 101,102,103,etc using a single hit? I am using postman. Please help me. As now I have to submit request by changing that field manually.
