Constructing SOAP Request

Hi All,

I want to submit soap request with list of 100 items. Below is the sample request.
Can anyone tell me how to populate list of 100 assetDetails?
I am using datasource step and getting 100 records of test data from database and I want to populate the request and submit all 100 records in 1 request


<urn:assets>
<urn:assetDetails>
<urn:identifier>171491283037</urn:identifier>
<urn:itemCode>CO.100200201.NA</urn:itemCode>
<urn:eventNumber>102</urn:eventNumber>
</urn:assetDetails>

<urn:assetDetails>
<urn:identifier>171491283038</urn:identifier>
<urn:itemCode>CO.100200201.NA</urn:itemCode>
<urn:eventNumber>102</urn:eventNumber>
