Regular Expressions

Regular expressions (also referred to as regex or regexp) are similar to wildcards in that they let you find matching strings of text. However, they are more powerful than wildcards.

To use regular expressions in the Find and Replace in Files window pane, enter the expression in the Find field, and from the Search type drop-down choose Regular Expressions.

When using regular expressions, backreferences are supported. For more information about backreferences, see http://www.regular-expressions.info/backref.html.

[a-z]

Matches any lowercase letter

[A-Z]

Matches any uppercase letter

\d

Matches any decimal digit

\D

Matches any non-digit

\s

Matches any white-space character

{…}

Explicit quantifier

For example, a{3} finds "aaa"

|

Alternation

For example, gray|grey finds "gray" or "grey"

(…)

Logical grouping

?

0 or 1 of previous expression; forces minimal matching when expression might match several strings within a search string

For example, reg(ular expressions?|ex(p|es?) finds "regular expression," "regular expressions," regex, regexp, or "regexes"
