I am new to JMeter, I want to fetch the 123 number from the below JSON response and store it in a variable. And user the value for further requests.
{"data":" Abcd efgh 123 successfully created","error":null,"info":null,"warn":null}
Can someone address to achieve it using BeanShell Postprocessor and Regular Expression Extractor or if any there is any other way to achieve the same.
Add Regular Expression Extractor Post-Processor as a child of the request which returns above JSON
Configure it as follows:
Reference Name: anything meaningful, i.e. number
Regular Expression: (\d+) successfully created
Template: $1$
You will be able to refer the extracted value as ${number} or ${__V(number)} later on where required.

Also be aware that JMeter 3.0+ comes with JSON Extractor, it is not applicable for your current enquiry however if later on you will need to get the whole attribute value(s) it will be much easier to use it rather than regular expressions
Regular Expression Extractor with (\d+) is the simpliest.
Reference Name: myNumber
Regular Expression: (\d+)
Template `$1$`
Match No. `1`.
It will be saved in myNumber variable

In Jmeter, run one API and get the below response. I want to extract File_Name & ReqId value from the below response using Regular Expression Extractor using only one "Regular Expression Extractor" . and pass these two values to another API, so how do that?
{"FileCode":["Aadhar"],"File_Name":"271954143_1_1.jpg","Aadhar_Features":[{"Confidence":"79.46","File_Code":"UIA","Count":1},{"Confidence":"87.87","File_Code":"GOI","Count":1},{"Confidence":"88.25","File_Code":"Aadhar_Slogan","Count":1},{"Confidence":"92.36","File_Code":"SatyamevaJayateLogo","Count":1},{"Confidence":"92.99","File_Code":"AadharLogo","Count":1},{"Confidence":"97.01","File_Code":"Aadhar","Count":2}],"ReqId":"REQ_1639032634869","Classes":[{"Confidence":[96.21741771697998,98.64940047264099],"Coordinates":["383,269,110.0,27","375,882,105.33333333333333,28"],"Count":2,"Name":"AadharNo"}]}
Here some wise man suggested using JSON JMESPath Extractor as it's faster, easier and more reliable.
If despite this you prefer using Regular Expression Extractor - here is the regular expression for the File_Name:
"File_Name"\s*:\s*"(.+?)"
and here is the one for the ReqId
Example Regular Expression Extractor configuration:

I have a response which have multiple values which need to pass in the next request. How can I right a single regular expression to capture that values and pass those to next request.
<id>583839</id>
<Clientno>543</Clientno>
If you configure the Regular Expression Extractor as follows:
textual representation of the settings:
Variable: DATA
Regular Expression: (?s)<id>(\d+)</id>.*<Clientno>(\d+)</Clientno>
Template: $1$$2$
You will be able to access the extracted values as:
${DATA_g1} - for 583839
${DATA_g2} - for 543

This is simple. You can use a regular expression extractor for this.
Just add 2 regular expression extractor config elements to the sampler from which you would want to extract data. Specify the below expressions in them and specify a relevant variable name. The template should be $1$ in both elements.
<id>(.+?)</id>
<Clientno>(.+?)</Clientno>
The above will provide you variables with the data you need.
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:

I'm trying to extract a number from string in single quotes.
For example: '0000123' in JMeter. This string comes from a CSV file configured in CSV data config.
Relevant regular expression extractor configuration will look like:
Apply to: JMeter Variable. Provide variable name which holds that 0000123 value.
Reference Name: anything meaningful, you can re-use the same variable name - it will be overwritten.
Regular Expression: (\d+)
Template: $1$
Other fields can be left as they are
