Comma separated list from excel

Thanks for your response. I have seen that link. My question is around how do I feed the multiple Ids for the request.

Here is my request
<ord:addTestsToOrder>
<ord:orderId>${DataSource#orderId}</ord:orderId>
<!--1 or more repetitions:-->
<ord:testIds>9655</ord:testIds>
<!--Optional:-->

<ord:foc>${DataSource#foc}</ord:foc><ord:addingUserId>1</ord:addingUserId>
<ord:userLocale>${DataSource#userLocale}</ord:userLocale>
<ord:labLocale>${DataSource#labLocale}</ord:labLocale>
<ord:owningLabId>${DataSource#owningLabId}</ord:owningLabId>
</ord:addTestsToOrder>

so if you see in the request there is testIds which accept one or moreIds, I want to pass this multiple ids in a data driven testing

Thanks
