Regular expressions allow for very powerful and flexible string search and replace operations. In traditional search operations the exact text to be searched for must be provided. Regular expressions allow a simple expression to be written that will match many different texts. For example, the expression “ab?cd” will match “abbcd” as well as “abccd”.
The special characters *, ?, [ and ] can be used to indicate special regular expression rules. The rules are:
- any character – This character must appear in the string at this location.
- * – Match any number of characters.
- ? – Match any one character.
- [a-c,r] – Match one character with any of the quoted range (in this case, the one character must be a,b,c or r).
To match an asterisk exactly, use “[*]”.
