Hi

I have the following regex which searches for a number with starting 4 numeric values and last value as numeric or alphabet

^\d{4,4}[A-Z0-9]$

[download]

When i try to match this regex in a user given input it easily matches. But when i try to run the same regex for pattern matching in a large text file than it fails to recognize the pattern in text file. i fail to understand why.. Help
