Re: Need some help in creating Regex Expression

[Endre Kovács]

Hi,

Also when in doubt, you can always experiment, check and learn regex in online 
places like:

https://regex101.com/#pcre 
or
https://regexr.com/ 

where you can also specify a test string you want to match for.
Best regards,
Endre

These two expressions should work:

^[cemp]st.*\.csv

^Canada[CEMP]ST.*\.csv
