I have this set-up in Jmeter as follows
TestPlan
GetToken
HTTP Request
Regular Expression Extractor
ReferenceName : token
Regular Expression: "Token": "(.+?)"
Template : $1$
Match No. : 1
Default Value : NO_TOKEN_VALUE
Debug Sampler
View Results Tree
When I run my test, I can see the result in View Results Tree. When I test my regex in RegExp Tester, it returns:
Match count: 1
Match[1][0]="Token": "1234567890"
Match[1][1]=`1234567890
However, when I view the Debug Sampler, I always get:
token=NO_TOKEN_VALUE
Does anybody know what might be causing this?
Make sure you have the correct settings for the fields in Regex Extractor config:
Apply To: Main Sample and Sub-samples
Response Field To Check: Body

I have nonce=nmjs7avwT1& in the response body.
I want only the nmjs7avwT1 part from above for the next request.
How can I write a regular expression for this?
Add Regular Expression Extractor as a child of the request which returns this nonce
Configure it as follows:
Name of created variable: anything meaningful, i.e. nonce
Regular Expression: nonce=(\w+)&
Template: $1$
That's it, you should be able to refer the extracted value as ${nonce} where required.

I am using Regular expression for pattern - and <em>(.+?)</em> for the password
But after running Jmeter I am getting request like below in View result tree Listner -
password=%7BUserid_g1%7D
Value of password is not storing after applying regular expression.
I have also set the variable as - {Userid_g2) in password field.
tell me where I am wrong?
Replace:
{Userid_g2)
by :
${Userid}
_g2 suffix indicates the capturing group of your regexp, can you show it ? there might also be an error there
My Test Plan (not working):
+ WebSocket Sampler
- Regular Expression Extractor
My Regular Expression:
Response data:
[Message 1]
0{"sid":"1BdTy3e4-jfrVM67AAAR","upgrades":[],"pingInterval":25000,"pingTimeout":60000}
How to get 'sid' ?
Regular expression "sid":"(.+?)" is ok.
Try use Match no(0 for Random) = 1

If you add a Debug Sampler after your request and look into the View Results Tree listener, you will see that your Regular Expression returns only one match:
As per Regular Expression Extractor documentation:
Match No. Indicates which match to use. The regular expression may match multiple times.
Use a value of zero to indicate JMeter should choose a match at random.
A positive number N means to select the nth match.
Negative numbers are used in conjunction with the ForEach Controller - see below.
Hence your Match No: setting is incorrect, you need either to remove 3 or change it to 1

In my Jmeter testing, I have a HTTP request which gives me Response data:
{"sessionid":"2da1c436-5ecf-4ce3-b908-705d9b3ed2a0","status":"successful"}
I have added a Regular Expression Extractor with following info:
Apply to: Main Sample only
Field to Check: Body
Reference Name: data1
Regular expression: "status":”(.+?)”
Template: $1$
Match No: 0
Default Value: REGEX_FAILED
However I never get ${data1} equal to successful (even though it is). It always gives me REGEX_FAILED. What am I doing wrong?
I see some odd quotes in your pattern:
Regular expression: "status":”(.+?)”
shouldn't that be:
Regular expression: "status":"(.+?)"
?
The response data in my test has this line:
<head><title>
My Title
</title><meta charset
I checked this regex in the inbuilt regex tester in Jmeter and it found the title.
(?m)(?is)<title>\n\tMy Title\n</title>
However, when I use it as a response assertion, the assertion always fails.
I have tried all settings in "Apply to" section. "Text Response" is selected for "Response Field to Test". I selected "Contains" for "Pattern Matching Rules".
I have a very similar issue with a regular expression extractor as well - the selected expression passes in the tester, but fails with regular expression extractor.
I believe it may have something to do with the multi-line nature of the response.
Any pointers?
try use:
(?<=<title>\s*)(\S.+\S)(?=\s*</title>) for find any title
(?<=<title>\s*)(My Title)(?=\s*</title>) for find 'My title'
Try the following:
Regular Expression: <title>(.+?)</title>
Template: $1$
Match: 1
Try to use xpath instead.
Use expression like //title/text() along with XPath Extractor - to extract title value, - and expression like //title[text()='My Title'] along with XPath Assertion.
In both the cases you have to ensure that that Use Tidy (tolerant parser) option is CHECKED - since you are parsing HTML (not XML!..) response.
