Hi, this is how it works.
JMeter has a map (i.e. a list of key/value pairs) of variables, a separate one for every thread/loop. When you run the RegExp Extractor, you are basically adding more key/value pairs to that map. If, for example, you set the RegExp Extractor options like Reference Name = refName Regular Expression = (.*),(.*) Template = My request is $1$ and $2$ Match No. = -1 Default Value = ERROR and it matches, what happens is some key/value pairs are added to the map. Among others, the variables "refName_X" (X is the match number) are set to the the strings as generated by the template. Read more about it in the manual http://jakarta.apache.org/jmeter/usermanual/component_reference.html#Regular_Expression_Extractor Lets say that for some thread your RegExp matched two strings, "A,B" and "C,D". Then (among others) you get two key/value pairs added to the JMeter variables map: ("refName_1","My request is A and B") and ("refName_2","My request is C and D"). "refName_3" etc are null. Those generated strings depend on how you set the Template. Then you can use those new key/value pairs in the ForEach Controller. If you set its options like this Input variable prefix = refName Output variable = outputVar Use Separator = yes It will keep setting the value of "outputVar" to the value "refName_X" (X = 1,2 ... is the loop counter) and running whats inside the controller until it encounters a "refName_X" which is not initialized (is null). In our example with two matches such ForeEach Controller will: 1) check the value of "refName_1", see that its not null, set the "outputVar" value to the value of "refName_1" ("My request is A and B") and run whats inside the controller 2) check the value of "refName_2", see that its not null, set the "outputVar" value to the value of "refName_2" ("My request is C and D") and run whats inside the controller 3) check the value of "refName_3", see that it is indeed null and stop the loop Then just use the value of outputVar (reference it like ${outputVar}) inside the ForEach controller to customize your elements. I am not 100% sure about all the details and implementation, but it seems to work as described above. I hope that helps.
