Replace component

The Replace component allows you to use regular expressions (regex) to find and replace text within a message body.

Configuration

The Replace component has the following configuration options:

Regex

Specify a regular expression to match the text that needs to be replaced.

Multiline (flag)

Specify whether to find and replace text across multiple lines.

Ignore case

Specify whether to find and replace text while ignoring case sensitivity.

Dotall (SingleLine)

Specify whether a dot (.) should match all characters, including newlines and other special characters.

Replace with

Specify the text that will replace the matched content.

note

• The characters \n (line feed), \r (carriage return) and \t (tab) will be unescaped, allowing them to be included in the replaced text. For example, you can to replace semi-colons (;) with tabs or insert a new line whenever the Regex matches.
• To escape a space, prepend a slash: \ .
• Leave this field empty to remove the matched text.

Group

Specify which group you want to use to find and replace text in, if the regular expression has one or more groups you can select.
