Read the book "Mastering Regular Expressions" or first 300 pages of it - trust
me, it is worth the labour (personal experience)!

or if you aren't into regex (which I find confusing and still am trying
to learn):

How can I check a string variable is based on alphabetical and numerical
characters?
For ex, I want to make a whois script for domainnames.
You may only use alphabetical, numerical characters and dashes ("-")
Thanks
