Ruby Regex to match nodes in Puppet file

Question

Hi everyone

This is my first post here, I am new to regex and I am struggling with writing a regex in puppet's nodes file, the regex should do the following:

I have two types of systems:

1) [a-z]qa-phppl

2) [a-z]qa-phppl-worker, I want to write two regex which parses these two system type.

(by[a-z] I mean that first letter can be any of the alphabets) The name format always remains the same except for the first letter which can be any alphabet.

it would be like:

regex for 1)

      do something;

regex  for 2)

  do something else;

Can any one please help,

Thanks

I just wrote a code snippet for your reference:

string str = @"qwqa-phppl-worker, 
            aqa-phppl-workerasd,
            1qa-phppl-workerasd .
                asdqa-phppl 
            asd.231asdqa-phppl asd ";
            Regex reg02 = new Regex(@"[a-z](qa-phppl)(-worker)[a-z]*");// qa-phppl-worker
            Regex reg01 = new Regex(@"[a-z](qa-phppl)");//qa-phppl
            MatchCollection ma = reg02.Matches(str);
            foreach (Match mti in ma)
            {

                Console.WriteLine(mti.Value);//print with -worker
                Match ma2 = reg01.Match(mti.Value);
                Console.WriteLine(ma2.Value);//print qa-phppl if matched.
            }
