Regex Filter
| Mule runtime engine version 3.8 reached its End of Life on November 16, 2021. For more information, contact your Customer Success Manager to determine how to migrate to the latest Mule version. |
Purpose: Matches string messages against a regular expression.
Minimum Configuration: The pattern string for the match.
Discussion: The RegEx Filter applies a regular expression pattern, such as a pattern that includes wildcards or other character substitution symbols, to the message payload. The filter applies the toString() method to the payload to convert the payload to a String. To ensure that the payload is a String, you might want to apply a Payload Filter to the message with a nested And Logic Filter.
