I have a link in my Request -
example.com/people/3176972
and my regular expression extractor is-
Regular expression: example.com/people/(.+?)
Template: $1$
Match no: 1
but it is only extracting only 3. I want to extract 3176972 number.
What am I doing wrong?
If you want to retrieve anything after the last slash, then just remove question mark from your expression:
example.com/people/(.+)
(question mark tells it to be non-greedy, hence it's taking 1 character).
If the last portion is always numeric, use
example.com/people/([0-9]+)
You should try this regular expression:
[0-9]+
Amend your regular expression to look like example.com/people/(.*) or example.com/people/(\d+) as your regex stops after first match.
See Regular Expressions chapter of JMeter's User Manual for more information on JMeter Regular Expressions.
Convenient way of testing regular expressions is using "RegExp Tester" mode of the View Results Tree listener.

Need help on building a regular expression to extract the value "2:_id93" and the uid. Here there are multiple sets of data with different status. How ever, i would like to search for the values corresponding to "In Update"
In Update
Can you try the below regular expression?
In Update(.*?)policytableId:(.*?)',null,\[\['uid','(.*?)'
Add Regular Expression Extractor as a child of the request which returns the above data
Configure it like:
Name of created variable: anything meaningful, i.e. id
Regular Expression: In Update.*searchResults:policytableId:(.+?)'
Template: $1$
That's it, you should be able to access the extracted value as ${id} where required.

If we are having dynamic left and right boundary in response, then how to correlate them in Jmeter?
I found few useful article to correlate in Loadrunner, by using text flag in web_reg_save_param like "/DIG", "/BIN", "/ALNUM", "/IG". Or we can do that using web_reg_save_param_regexp.
In Jmeter you use the relevant Regular expression in Regular Expression Extractor added as a post processor of the request.
for example for LoadRunner correlation:
Source: “GraphA123567EndGraphA”
Solution:
web_reg_save_param_regexp(“ParamName=CorrValue”,
“RegExp=\“Graph[A-Za-z]\”, \“([0-9]+)\”, \“EndGraph[A-Za-z]\””, LAST);
Result: 123567
You will use Regular Expression:
Graph([A-Za-z]+)(\d+)EndGraph([A-Za-z]+)
with Template: $2$ to get relevant group and in Jmeter ParamName is Reference Name
JMeter doesn't operate "boundaries", the most popular Post Processor is Regular Expression Extractor which can handle both static or dynamic "boundaries" which you can set using Perl5-style regular expressions.
For example if you want to extract numeric value between foo and bar the relevant JMeter regular expression would be foo(\d+)bar
If you are looking for a mix of numbers and letters you can use foo(\w+)bar
The same approach you can follow if your response data is like foo1_A_VERY_INTERESTING_STRING_bar2 where 1 and 2 are dynamic:

Regular Expression -"p_instance" value="(.*?)"
Match count: 1
Match[1][0]="p_instance" value="11917272245034"
Match[1][1]=11917272245034
When added $1$ in template - error is displayed(request is not created)
$1$$1$ is dding duplicate strings in the request.
What should be the template to fetch this value
Just add a Debug Sampler to your Test Plan - this way you will be able to see all the variables generated by the Regular Expression Extractor in the View Results Tree listener. See How to Debug your Apache JMeter Script article for more details.
Going forward when asking for a help with the regular expressions include essential part of the response and indicate which value you are looking for.
Here comes mandatory advice not to use regular expressions for parsing HTML and suggestion to use CSS/JQuery Extractor or XPath Extractor instead.
I am creating regular expression in Jmeter for following response:
/cars/contractDispatcher.do?
operation=programHeader&id=265&hierarchyName=ContractAsHierarchy
id=265 is dynamic in this expression, I am tried with following expression:
/cars/contractDispatcher.do?operation=programHeader&id="
(.+?)"&hierarchyName=ContractAsHierarchy
Also:
operation=programHeader&id=([^>]+)&hierarchyName=ContractAsHierarchy
Question
But these are not working could anyone tell me correct expression.
Thank you in Advance.
Use the following Regular Expression Extractor configuration:
Reference Name: any variable name, i.e. id
Regular Expression (single line): operation=programHeader&id=(\d+)&hierarchyName=ContractAsHierarchy
Template: $1$
Refer extracted value as ${id} where required.
You can use RegExp Tester mode of the View Results Tree listener to evaluate regular expressions directly against response

I did read few responses but my regular expression extractor is not working.
Mine is a simple case where this is my response
token.id=AQIC5wM2LY4Sfcz4cOT2RrremxWJmM3llZmPl6k0bP_r5D4.AAJTSQACMDUAAlNLABQtNDI1OTg4NzgxODg5MDM1ODU2NQACUzEAAjI3
I am trying to grab the value using this expression
token.id="(.*?)"
which is not saving the value into the variable i assigned. My next request when trying to use the value fails since its not grabbing it.
Can someone let me know what exactly is missing. thanks.
There are few problems with your regular expression:
You need to escape dot between "token" and "id" with backslash as it is a special character. See Literal Characters article for more information.
You don't need the quotations marks as your response doesn't contain them (does it?)
So your regular expression needs to be amended as token\.id=(.*) (however I would rather go for something like token\.id=(\w.+)
You can use View Results Tree listener in "RegExp Tester" mode to test your regular expressions directly against response without having to re-run the request.
See Regular Expressions JMeter documentation chapter and How to debug your Apache JMeter script guide for extended information on the above approaches.
