We need to identify a response xml file generated by the system. The file is named as below:

"b2bs.devenv1.bt.co.uk_cn_payloadBT_Wholesale_Comm unications_Provider_1_WholesaleProvider_ServicePro vider_Release4_cpa_" + unique number.

Due to the unique number getting added at the end for every execution, we are not able to identify the file during playback and the test is failing.

We are exploring different options. One of them being use of regular expressions. But QARun Help does not say anything about support of reg exp.
