String Replace

Replaces all occurrences of a substring or regex pattern within a string.

Replaces all occurrences of a target string or pattern within an input string.

Operation Modes#

The node has two modes, controlled by the op input:

  • String: Performs a literal, case-sensitive replacement of the substring text.
  • Regex: Treats the substring input as a regular expression pattern to find matches.

Regex Details#

When using Regex mode: - The pattern syntax is based on Go's RE2 engine. - You can reference capture groups from your pattern in the replacement string using $ notation. - Example: $1 for the first group, $2 for the second, and ${name} for a named group.

Example#

  • input: "The year is 2024."
  • op: Regex
  • substring: (\d{4})
  • replacement: 2077
  • result: "The year is 2077."
