Foreach loops with groups
I have a regular expression that returns three groups:
.*sendRequest\((\d+),(\d+), '(\d+-\d+).*
I then have a foreach controller in which I map input var "inputVar" to
output var "outputVar" with the "add '_' before number" checked.
How can I access variables in a sample controller within the foreach loop?
I've tried:
${outputVar_g1},${outputVar_1},${outputVar1},${outputVarg1},${outputVar_g1_1
},${outputVar_1_g1}
Nothing seems to work. The result view tree shows the sample is being
called but the params output the literals and don't seem to replace the
variables with values.
I'm using jmeter 2.1 and I see in the changes that "ForEach Controller can
now loop through sets of groups" was fixed in 2.0.3
I'm sure I'm missing something simple.
Thanks in advance,
Justin

Try
ForEach:
Input: RegexVar_g
Output: outputVar
Add '-': unchecked
and refer to
${outputVar}

Posted by MA <ma...@gmail.com>.
This was an old post but replying because it might be useful for anyone who
wants to use it.
The easiest way I could get all the variable values in ForEach Controller
with more than one group was
1) Since ForEach needs a regular expression with Match number negative(say
-1)
eg. the sample html code that needs processing is as below
<for label="jmeter">Jmeter</label>
<for label="user"> User </label>
----
Use the postprocessor -> regular expression extractor
the var is inputVar
the regular expression is <for label=(.+)>(.+)</label)
Match Number is -1
Loop Controller
set the loop variable to the number of matches returned by
${inputVar_matchNr}
Add a pre-processor element counter with start value 1 and increment 1 -
as a child to the loop controller
Add a ForEach Controller as a child to Loop Controller after the counter
input variable - inputVar_{C}_g
return variable - returnVar
Add "_" before number - uncheck
Now ${returnVar} returns jmeter,Jmeter,user,User all variables in all
groups.
