Is this C#? I've not seen that method of creating named capture groups. Though, if you are going to name your capture groups, you may as well retrieve them by name rather than by index.

Also, you only check if the line contains the string to find. Nowhere in your code do you actually look for that as a key or value.

And consider that regular expressions are greedy. Your "Value" capture group will capture everything after the first ": ".

Also, according to your regular expression, you can have an empty value ("*" means zero or more). I suspect that is not what you want, but maybe you do.

Finally, I'm not really sure how "SERVOFW: SDLSUPPORTED: 1" fits into the key/value scenario. Maybe that's a typo.

Based on the assumption that values can have spaces, but keys can't have spaces, this may be a more appropriate regular expression:

(?<KEY>(?!:| ).)+: (?<VALUE>((?!:).)+)(?= (((?!:| ).)+:)|$)


Keep in mind that this will find all matches, so you don't watch to just find the first match as you are doing in your example. You want to loop through them all and compare the key/value against the word you are looking for.
