Regular Expressions Character classes Match different, similar words
Example
Consider the character class [aeiou]. This character class can be used in a regular expression to match a set of similarly spelled words.
b[aeiou]t matches:
- bat
- bet
- bit
- bot
- but
It does not match:
- bout
- btt
- bt
Character classes on their own match one and only one character at a time.
