I have created a User Defined Variable with name as "Status" and a default value as "Started".
I got a HTML Response, with following content:
<SPAN id="ApplicationStatus"> Interrupted</SPAN>
I want to get the Span Id value and use in beanshell samplers to process further either in If Controller or Switch Controller.
I used Regular Expression extractor to extract the value needed and its working too.
But when i say vars.get("Status") will always return me the default value "Started".
Is there a way where i can extract the required value "Interrupted" and substitute that to the user defined variable "Status"?
Yes you can get that value of #ApplicationStatus into your User Defined Variable (UDV).
You can use regex but really you shouldn't for this type of parsing I'm not going to get into many reasons why.
Here is how you can do it using alternative (better solution IMHO) :
String html = "<SPAN id=\"ApplicationStatus\"> Interrupted</SPAN>";
Document doc = Jsoup.parse(html);
String value = doc.select("#ApplicationStatus").first().text();
//Put value in UDV Status
vars.put("Status", value);
You can add this to your sampler that does this kind of parsing i.e Beanshell sampler, here are the imports (which go above this code) :
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
Please note that this code is Jsoup dependent so you will need to download jsoup jar and put it in your $JMETER_HOME/lib directory.
Hope this sheds some light on your issue.
Update
If you want to avoid Java, I've written small jmeter post processor component that extracts text value from HTML element. Take a look at :
https://github.com/c0mrade/Html-Extractor
If you go over the steps how to install the post processor from the page above, you would use it as follows :
Right click on your sampler. Add a Post Processors -> Html Extractor , in the jquery selector field write #ApplicationStatus and store result in variable of your choice (Status). Following this add Debug Sampler, if in your Debug sampler there is variable Status with the value Html Extractor is working! you're done!
I can't reproduce your issue.
Here is my plan:
- User defined variables with variable Status
- Thread Group
- HTTP Request
- Regular expression extractor with reference name = Status
- Beanshell Sampler that logs Status variable
Beanshell sampler logs value that was received in Regular Expression Extractor

I recorded the .JMX script in Jmeter and one of the request is as below
POST http://www.hello.com/auth/nqa/md/login
Body data:
{"domainId":"nqa","code":"12345skdkdk"}
I would like to send the "code" field dynamically and for that I added the regular expressing extractor as below enter image description here
When i re run the script , the code value is not replaced with the dynamic value.
Not sure what part i am missing in the regular expression extractor or in the Body data field
First of all, you cannot extract the value from the request body using the Regular Expression Extractor, normally you should extract the dynamic values from the previous response so inspect the whole flow using View Results Tree listener and look for your "code" value there
Your regular expression extractor in its current configuration will return random value in the parentheses so it could be domainId, nqa, code or 12345skdkdk. Going forward if you need to get some dynamic data from JSON go for JSON Extractor or JSON JMESPath Extractor
List item
you should do three-step of below
go to the random variable according below picture
Define random variable name . in this case we set variable name to code1 and set min & max value to this
Use ${code1} variable to your data section
In my first request I am able to extract the value using Regular Expression Extractor which is clearly visible into the debug sampler. The value is extracted by setting the following options in Regular Expression Extractor:-
Name of Created Variable:- instanceUID
Regular Expression:- "InstanceUid":"(.*?)"
Template:-$1$
Match No:-1
Default Value:- (Blank)
The value that I want to pass in the next POST request is visible as:-
instanceUID_g1=2ab5dfb8-a217-4ff2-9025-523565b7b7ad
And the body for the next HTTP POST request is set like this:-
${"iInfo":{"InstanceUid":"${instanceUID_g1}","Registry":"${Registry}"}}
When this request seen in detail inside View Results Tree looks like:-
${"iInfo":{"InstanceUid":"${instanceUID_g1}","Registry":"AAX"}}
As seen the value of ${instanceUID_g1} did not get substituted in the POST body as was for variable ${Registry} which was taken from CSV config.
Being new to Jmeter can anyone suggest what did I miss?
Most probably your Regular Expression Extractor placement is not very correct, be informed about JMeter Scoping Rules concept
If you place Regular Expression Extractor as a child of the request - it will be applied to this request only
If you place Regular Expression Extractor at the same level as several requests - it will be applied to all of them
in the latter case it will be applied 1st to 1st sampler, then to Debug Sampler, then to 3rd sampler so on 2nd step it will be overwritten, most probably that's your problem
Also it appears that you're getting the data from JSON so it makes more sense to use JSON Extractor or JMESPath Extractor
I use JMeter 4, I have a problem in a JMeter JSON Path Extractor.
I have done an HTTP Request (POST) to a service that I wan't to test.
Response data from the service is
{"rid":"661ff2d7-12e8-e811-8110-00215a9b9851",
"participation":{"rid":"ed8cfced-0063-4fda-92fd-b23f50197797"}}
I wan't to extract the first GUID witch is allocated to the first rid.
As JSONPath Expression I have used $.rid and wan't to assign that value to a JMeter variable. Therefore I have checked the radio button JMeter variable and entered my JMeter variable which is int_rid.
When I execute my JMeter testplan the int_rid variable will be null.
In JSON Extractor If you check the radio button JMeter variable it expect to search inside the contents of JMeter variable, which you don't want, usually Main sample only is enough
Main sample only - only applies to the main sample
Sub-samples only - only applies to the sub-samples
Main sample and sub-samples - applies to both.
JMeter Variable Name to use - assertion is to be applied to the contents of the named variable
Put int_rid in Names of created variables field and chose Match No. 1 to find the first value
My task is to make a request and save some data from the headers in a variable and use it later in another requests.
So I've added an http request and added an regular expression extractor. Here is my setup:
And then I've created another request and I'm using the LocationToken variable, but there the variable has the default value (dd). here is the response:
So, as you can see, the pattern patches on the headers. So what have I done wrong?
In Regular Expression Extractor, under Apply to section, you should select Main sampler and sub-samplers option but not JMeter Variable.
Regular Expression Extractor saves the value into the variable which we specified in Reference Name field.
in the question,
Reference Name: LocationToken
in later request, you refer the value as follows:
${LocationToken}
I have a series of interconnected pages to test using JMeter. The problem is that the initial page has a Javascript variable in source section which is more of a session variable. This variable is passed in the URL for subsequent pages.
So basically I would like to fetch this javascript variable when I load the initial page from the source section and pass it to next URL(s).
Is there a way I can achieve this using JMeter.
Are you able to see the session variable in the response of initial page?
(in view result tree listener)
If yes, then correlate this value and pass the variable in to next request (use regular expression extractor for fetching the value, still if you are finding some issue in correlating the value than please share the response of first request over here so that I can provide you regx for that)
People mostly Regular Expression Extractor to fetch dynamic values from previous responses, in general the process looks like:
Add Regular Expression Extractor as a child of the request which returns desired data
Use Perl5-style regular expression to match what you're looking for
Provide a template to choose match group - ususally $1$ if you looking for a single value
Provide a reference name to refer the extracted value, i.e. foo
Use extracted value as ${foo} where required
You can visualise JMeter Variables using Debug Sampler and View Results Tree listener combination.
The easiest way to debug your regular expressions is using View Results Tree listener in "RegExp Tester mode"
