Regular Expressions for extracting Correlation Parameters in IBM RPT

Question

I have a problem here. The line in response goes something like this:

*14*PerfTest1 PerfTest2*14*Individual

Here I want to extract out PerfTest2 for a LastName value.

But the first name also would differ for some test data. *14*Individual would be the same for all the responses. Need help in extracting PerfTest2 from similar lines like above.
