Regular expressions allow you to perform powerful context searches in
variable-length strings. They provide a a powerful set of pattern
matching capabilities by combining the following
Character Classes are groups of possible characters at a point in the search
Collation Classes are sets of characters and are treated like a range
Metacharacters are operators that specify search algorithms
Metasequences are operators created by two metacharacters or literals
Literals are characters, character sets and words more...
