Spotfire Custom Expressions Characters

[Kom Son]

What does . $ + mean when used in custom expressions for "includes" or "contains"

[Fredrik Rosell]

Hello,

 

I assume you refer to the use of regular expressions, available in some expression functions If so, as regular expressions is a general, non-Spotfire-specific concept, there isn't very much in the Spotfire documentation itself but I recommend simply googling for "regular expressions", and you'll find tons of great resources. I e.g. like usinghttps://regex101.com, which both has a good quick reference and makes it easy to test expressions.

. = any character except new line

$ = End of string

+ = one of more

 

Best Regards

Fredrik
