Question

I want to write a regular expression that can match the following strings:

OFF
ON
String
Valve

I was thinking to write ^(?<arrivingString>[a-zA-Z]{?})$.

Now I don’t know what to write within the curly brackets, as the value of arriving string is different and random.

Thanks

Answer 1

^(?<arrivingString>(OFF|ON|String|Valve)).*

This matches those 4 words only provided:

• Mutiline is enabled for the Regex
• The words are at the start of each line

This Regex will match every line in it’s entirety provided it starts with any of those 4 strings. The captured group arrivingStringwill contain whichever of the four words was found.
