Start and End

By testing for the start and end of the string you can test the entire content.

In the fifth tutorial on "Regular Expressions" we look at the first of the characters that have special meanings in expressions - the ones that allow us to identify the start and end of the text. By specifying that what we want to match includes the start and end of the string we can natch against the entire content - very useful when we want to validate the content.
