Answer 1

why do you want to use regex?

You can do it with built in string functionality, for example:

if(myString.StartsWith("$$$") && myString.EndsWith(name) && (!myString.Contains("<") && !myString.Contains(">"))) DoSomething();

You might want to create some more advanced html tag logic. My example assumes that a < and a > in the same string is a html tag.

Edit : I misunderstood your question. You can use substring, example:

var str = myString.Substring(myString.IndexOf("$$$")+3, myString.IndexOf("name")-3);

The indexes are +3 since you don't want to include $$$ or name. If you have many valid sub strings in one string, you have to iterate through it and remember the last index of $$$, and search for the next one from that position.
