Regular expression

Enter plain text representing a valid regular expression and optionally use field codes to insert field values.

Additional options

Choose one of the following additional options to further refine how to evaluate the value against the regular expression. 

OptionDescription

Case insensitive

The evaluation will ignore the case of the input value

Multiline

Characters ^ and $ match just after or just before, respectively, a line terminator or the end of the input sequence. By default, these characters only match at the beginning and the end of the entire input sequence.

Dot all

"." matches any character, including a line terminator. By default, this character does not match line terminators.

Literal

Input string is treated as a sequence of literal characters. Metacharacters or escape sequences in the input sequence will be given no special meaning. Case insensitive mode retains its impact on matching when used in conjunction with this mode.

Negate condition

The condition will be met if the provided regular expression does not match.
