Regular Expression Evaluator#

The Regular Expression Evaluator applies Regular Expressions (RegEx) to input data for pattern matching, extraction, replacement, or validation purposes. It is useful for tasks such as parsing structured text, extracting specific data points, or transforming text using substitution patterns.

Evaluator Behavior#

The Regular Expression Evaluator applies a regular expression to input data and returns results that match the expression.

  • EvaluateUntilTrue: Stops processing when an expression returns a true value and outputs the corresponding result.
  • EvaluateAll: Evaluates all configured expressions and outputs all results.
  • Clear Inputs: When enabled, resets the inputs after task execution.
