Hello Philippe -
To answer your questions under each section:
1) I don't see a good way to remove sections of a template based on a
parameter...
>Can you clarify wether you want to remove the full block ? what does b/t
>mean ?
b/t == between.
I need to remove the entire section if the ${keyword2} value is empty. If
keyword2 is missing, I need to skip a section of the document because the
system I’m posting cannot handle empty values. Thus, it would be nice to
have functionality like this:
====================================
. . .
${if-present:keyword1}
{
"type":"Label",
"name":"${keyword1}"
},
${/if-present}
${if-present:keyword2}
{
"type":"Label",
"name":"${keyword2}"
},
${/if-present}
. . . etc.
====================================
I don’t really see how this would be possible with an If Controller. What
I’m posting is a large JSON document with many user parameters, all of
which need their sections removed if they are not present.
2) Templates are not actually supported…
I’m still stuck on this issue: I basically need to do this:
a) Read in a file (the path must be relative to the .jmx file - nothing
else makes sense)
b) Replace variables in that file with values from a CSV file
c) Take out the sections of the file that apply to empty variables
d) Do an HTTP Post with the result
At the moment a & c seem impossible.

I don’t understand - the issue is that the Http Request file path is not
relative. That effectively means it cannot be used unless you put your
file next to the JMeter jar file. Should the ability to include a file as
the body of the post just be removed as a feature?
4) The CSV Dataset Config component seems to be designed to only iterate via
the loops of a Thread Group

OK, I can experiment with this - some documentation on how to do this would
help. Web searches always steer people toward just putting the CSV file in
a ThreadGroup and using the ‘stop thread on EOF’ option.
Thanks for the help,
