Post-Processors are actions which are performed after your sampler has been executed. You can use them to perform some actions on your response or extract some values out from the response and save them in a variable which can be used later.

Regular Expression Post-Processor uses Regular Expression string to fetch some values from response of your request. The value(s) which is extracted can be stored in any variable and can be reference in any further request in the test plan.  Values can be extracted from response body, header, URL, response code and other provided fields when you add this processor.
