[Regexp] Regular Expressions and file selection

[Scarlett, Mervyn]

We use SeeBeyond's eGate application as an Integration suite and Regular 
Expressions are used in the configuration of an eWay to specify which files are 
to be picked up. 

I have a problem writing a Regular Expression that will select all the files 
from a directory where their names match the pattern asn_header.datnnnn or 
asn_container.datnnnn, where nnnn is a four digit number, but leave the files 
called asn_header.dat8788 and asn_container.dat8788

Can anyone suggest a solution?

Mervyn Scarlett
