This topic defines language for the flex parser regex node.

Regex searches the stream payload starting at the read position for matches to a provided regular expression. If matches are found, the offset from the read position and, optionally the matched string, is returned. Any child elements execute. If no matches are found, child elements do not execute.

valueA regular expression to find.
length (optional)A limit to the length of the payload to be searched. If a limit is not provided, the remainder of the payload is searched. It is recommended to always use the smallest value possible here in order to reduce the effect on performance.
