Character Classes

A character class contains a list of one or more characters. Use the bracket expression to create a character class and to match an expression that has a character in a given space.

You can use metacharacters, such as

-, ^, \, [:...:]

, to perform an advanced search on character classes. Use class shorthands, such as \d, \D, \s, \S, \w, and \W, as shortcuts for character classes.

The following table lists the precedence of character-class operators from highest to lowest:

Priority	Description	Character Class
1	Literal escape	\x
2	Group of characters	[aeiou]
3	Range of characters	[a-z]
4	Union of characters	[a-e][i-u]
5	Intersection of characters	[a-z&&[aeiou]]
