Re: problem in reading variable set by capturing groups in regex
with "Match No." set to negative
Hello,
Thanks for your explanation.
In fact my superior only wants nothing but regular expression (and not even
XPath) so at this moment I have to figure out with his regex.
I find and also admit that I have misunderstood "refName_n_gm, where m=0,1,2
- the groups for match n " in the user's manual. n means the nst ocurrence
matched by the pattern and is not a short for "negative".
As for Debug Sampler I read some variables like these:
tgDataColumn_1_g=9
tgDataColumn_1_g0=
19/11/2009
R0223437
XXYYZZ Co. Ltd
778134593
PHOTOCOPIEUR
9742.66
63
T
ACCORD
tgDataColumn_1_g1=19/11/2009
tgDataColumn_1_g2=R0223437
tgDataColumn_1_g3=XXYYZZ Co. Ltd
tgDataColumn_1_g4=778134593
tgDataColumn_1_g5=PHOTOCOPIEUR
tgDataColumn_1_g6=9742.66
tgDataColumn_1_g7=63
tgDataColumn_1_g8=T
tgDataColumn_1_g9=ACCORD
The next iterations will give something like:
tgDataColumn_2_g1=...
...
tgDataColumn_2_g9=...
But what should I do to iterate first on the different lines (occurrences)
then on the captured groups on each line?

Re: problem in reading variable set by capturing groups in regex
with "Match No." set to negative
Posted by rosiere <sh...@gmail.com>.
Hello,
As for iteration, I read these from Debug sampler's out put:
tgDataColumn_1_g=9
tgDataColumn_1_g0=
19/11/2009
R0223437
XXYYZZ Co. Ltd
778134593
PHOTOCOPIEUR
9742.66
63
T
ACCORD
tgDataColumn_1_g1=19/11/2009
tgDataColumn_1_g2=R0223437
tgDataColumn_1_g3=XXYYZZ Co. Ltd
tgDataColumn_1_g4=778134593
tgDataColumn_1_g5=PHOTOCOPIEUR
tgDataColumn_1_g6=9742.66
tgDataColumn_1_g7=63
tgDataColumn_1_g8=T
tgDataColumn_1_g9=ACCORD
Which means that the first occurrence matched by regex will create variables
named "tgDataColumn_1_g..", the second will create "tgDataColumn_2_g..", and
so on.
Now I want to find the syntax to iterate each occurrence i, from,
tgDataColumn_i_g1 to tgDataColumn_i_g9, so that I will be able to create an
Http request on each occurrence, with 9 parameters, each parameter taking a
captured group (from g1 to g9).
However I cannot find such an explanation in ForEach Controller's paragraph,
in the user manual (or I haven't fully understood it).
So what is the syntax for iterating on the "i"st occurrence?

Not sure I understand what the last sentence means.
The normal way to use groups of variables is the For Each Controller:
