Regular expression in xml check point

[dima_mazyar]

Hello!
I have a problem using xml check point(from resource). Actually the system I'm testing generate an xml file all the time I'm running the test with a new time stamp. So all the time test is failed, because the Qtp cannot find xml file with such name.
My check point:
XMLFile("BpsUnitInternal_0000_ACC_20100").Check CheckPoint("BpsUnitInternal_0000_ACC_20100728153800.xml")

Regular expression I used: C:\\Rmu3\\Data\\Queues\\Verify\\BpsUnitInternal_0000_ACC_\d+\.xml
