using variable in a RegExp extractor
The following is a working expression ( the snippet of the text the
expression is created for is at the bottom)
PostingGridView\$ctl(\d+).+\n.+\>111\<\/td
If I put in the batch number (111 above as an example) manually, the
expression works ( above works )
but I need it to work dynamically and get the batch number automatically. -
I am trying to extract (\d+)
when I use the variable ${BATCH}, as in the example below the expression
does not evaluate.
PostingGridView\$ctl(\d+).+\n.+\>${BATCH}\<\/td
can you use variables in JMeter expressions??? if so what am I doing wrong
-I have verified that the variable is populated correctly by using the debug
sampler and I also use the ${BATCH} variable other places before and after
this RegExp.
If I can't is there a way for me to get around this?
Thanks!!
Snippet of the response that the RegExp is running against: (you can see
that '78' is the number I am trying to return based on the batch number of
'111' in this example )
<input id="PostingGridView_ctl78_CheckBox1" type="checkbox"
name="PostingGridView$ctl78$CheckBox1"
onclick="javascript:setTimeout('__doPostBack(\'PostingGridView$ctl78$CheckBox1\',\'\')',
0)" />
</td><td>111</td><td>TEST</td><td>IN
BALANCE</td><td>09/25/2009</td><td>09/25/2009</td><td style="text-
thanks again!!

You don't need to escape ">" or "<" or "/".

Which version of JMeter?
Try enabling Debug for the RE Extractor - select it in the tree and
use the Help menu.
This will show the exact RE in the log file.

What does the JMeter log file show when you enable Debug on the RE Extractor?

Re: using variable in a RegExp extractor
Posted by cmrz <cm...@yahoo.com>.
my updated regular expression is: PostingGridView\$ctl(\d+).+\n.+${BATCH}
this once again works if I use a number in place of the ${BATCH} variable.
I have no doubt that the expression is working - I even tried it inside a
Perl script I wrote up for this and it worked fine using the variable. so
it is some way JMeter is handling or not handling this expression.
I am using Jmeter v. 2.3.4 downloaded 1 hour ago from their main site and
still the same problem.
please help !

When parsing the string for function references, certain characters
(such as $) are treated specially. E.g. if one wants to enter the
string ${X} and not have it treated as a variable reference, it needs
to be entered as \${X}. However the \ must then be removed. Using \\$
means that the final string will contain \$.
If the string does not contain any function/variable references, it is
used as is.

"Try enabling Debug for the RE Extractor - select it in the tree and
use the Help menu."
The debug messages are written to the jmeter.log file.
You may be able to solve the problem by using the following RE:
PostingGridView\\$ctl(\d+).+\n.+${BATCH}
i.e. try \\ before $ instead of just \.

I can't get the debug working right. Enabling debug does not seem to do
anything and I am not sure how to get this log file.
Can you let me know how to do this and I will move forward?
thanks!
