I have an http post request which replies with a number in the response body.
I am trying to use a Regular Expression Extractor to extract this number:
I am doing another post request using the extracted value. Unfortunately, the variable seems to be null.
Any idea of what could be wrong?
I am using JMeter 2.13.
There are 2 available solutions:
Use ${REGION_ID_g0} when referring extracted value
Change your regular expression to add grouping as (\d+)

I am working on log-in scenario for Jmeter. Once I logged-in, I am redirected to the below request:
https://analogb2c.b2clogin.com/analogb2c.onmicrosoft.com/B2C_1A_ADI_SignUpOrSignInWithKmsi/SelfAsserted?tx=StateProperties=eyJUSUQiOiJlOWRiNTU1Zi05N2ZmLTRmOTYtOGQwMC0yOTc2MGNlYmE4ZDYifQ&p=B2C_1A_ADI_SignUpOrSignInWithKmsi
How do I extract the Query String Parameters "tx" and "p" and "X-CSRF-TOKEN" that is in the request headers? What is the regular expression to get the values? I will use the value to the next succeding request. Thanks
Query String Parameters
For the tx it would be something like:
tx=(.+?)&
For the X-CSRF-TOKEN it would be something like:
X-CSRF-TOKEN:\s*(.*)
If you have problems with JMeter Regular Expressions - you can consider switching to the Boundary Extractor, it basically extracts everything between left and right boundaries, doesn't require any domain knowledge and works much faster. More information: The Boundary Extractor vs. the Regular Expression Extractor in JMeter
From the below string
https://ABC.somewebsitename.com/Account/AutoLogOn?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIxMDEyMzk3ODMiLCJ0YXJnZXRDb3VudHJ5Q29kZSI6IkpQIiwiZXhwIjoiMTU3OTUxMjc4MiJ9.QhfDKvZXSrqTjGYsBaZUd6ErbYoOJUdta0efws2SI-nv0VYqUvByHvoKbWVGvd89RmOi-KV33CDHU8NE_Pl0NA
I want to extract the value after token and send it as a parameter in next request for that I used Regular Expression extractor as below
But in the next request parameter, I am not able to get those values
Am I missing something, can you help me on this?
Note: I have followed the link Extract Location from Response Header with JMeter but still no use.
Your regular expression is missing capturing group, I believe you should amend it like:
https.+token=(.*)
Demo:
However if you just need to extract the token and append it to the next request it is easier to consider Using the HTTP URL Re-writing Modifier
Regular expression should be token=(.+?)$
Also set the Field to Check to URL in the Regular Expression Extractor element.
I did some trial and error, and got the answer,
In the Regular Expression Extractor, used as
Regular Expression: Location: .+\/AutoLogOn\?token=(.*?)\n
(//test-clinicalpl.hee.heaelth.nz/nzty/?encryptedRequest=B3616B90E8CD11B90E99022FE7998834453B92493671C1AF3DB24346493F5364579EF1E9A9FED64B25E1593A3EF768A887B89E5A5A73EDD7BD6D88A1C4ED2D0E994820BEE64B410113603687174086C8B0FEEFF051774184&mac=6252A91F473FD4F4C66E17A7928AFAA48E0E612A&expiry=0000016954D411EC
encryptedRequest, mac and expiry are the dynamic values changes everytime
I wrote this as there regular expression extractor as below:
encryptedRequest= (.*?)& mac=(.*?)& expiry=(.*?)
Right click on the request and add post processor: Regular Expression Extractor.
Use this RegExp
encryptedRequest=(.*)&mac=(.*)&expiry=(.*)
Specify Variable name, myEncryptedRequest for example
Set Template - $1$ for the first matching ($2$ - for the second mac, etc).
Use this values in next requests as ${myEncryptedRequest}
You may add more Regula Expression Extractors to parse another values.
Please refer to JMeter component reference for more details and Guide how to extract and re-use as variable
I need to extract the string to the right of the equal sign character in an Apache Jmeter project. I am not familiar with Regular Expression syntax at all, but I think this would be the easiest way to extract it. The url is: https://myserver.com:portnum/im;jsessionid=48E10C95151BFB84D795C90FBC31E8E6
I only need the string to the right of the equal sign, not including the equal sign. My question is, what regular expression should I use to extract the string? Thanks!
It is as simple as =(\w+)

Also be aware that there are "smarter" ways of handling JSESSIONID:
In case if it comes as a Cookie you can get its value via HTTP Cookie Manager
If it is being passed as an URL parameter you could use HTTP URL Re-writing Modifier
i am new to jmeter and i am using regular expression extractor to extract document number which is between
<showDocument> 834446$$$$1601Consent </showDocument>
which field should i check Body or Response Header
The relevant Regular Expression Configuration would be:
Reference Name: anything meaningful, i.e. showDocument
Regular Expression: <showDocument>(.+?)</showDocument>
Template: $1$
You can access extracted value as ${showDocument} where required. See Regular Expressions chapter of JMeter User Manual for more details
By the way, your response part looks like XML so it might be easier and better to consider using XPath Extractor instead. In that case XPath Tutorial would be extremely helpful.
