Queries in Parameterization and Correlation

Hi,

I am using soapUI 4.0.0 currently for load testing purpose.

Here are some of the issues I am encountering.

1. As part of parameterization, is it possible to read values in unique manner from a parameter file? If possible, please share how to implement.

2. For handling dynamic values in the SOAP request, please suggest how to creata XPath query with unique boundaries. Assuming that we have 2 dynamic values in the SOAP request with 2 same left and right boundaries, how can we handle them?

Please help me in reverting back replies to the above queries.

Thanks
Lakshmi
