In JMeter, I'm trying to extract the values of property key values using CSS selector extractor, for the attached HTML body
I used the expression #propertySummaryList > div, but not seeing any response in debug sampler.
I would use Boundary Extractor, simpler and faster.
Use parameters:
Left Boundary : propertykey="
Right Boundary: "
Match No.: -1
Allows the user to extract values from a server response using left and right boundaries
Don't post code as image as it's way harder to reproduce your issue
Try out the following selector instead: div[class=propertySummaryList] > div

Below is a sample response from JMeter tool.
<input name="requestId" type="hidden" value="-1859748216"/>
I try the following XPath //input[#name='requestId'], but it doesn't work, I would like to take only the numeric value -1859748216
You need to get the value attribute using /#value
//input[#name='requestId']/#value
Prefer using newer/improved XPath2 Extractor over XPath Extractor
If you really want to use XPath, you need something like //input[#name='requestId']/#value
However XPath Extractor is quite resource intensive as it keeps entire DOM in memory, when it comes to getting the values from HTML content I would rather recommend going for CSS Selector Extractor leaving XPath for XML or when CSS Selectors are not powerful enough
Example setup:

How to Use the CSS/JQuery Extractor in JMeter
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 have JSON responce
{
"sessionName":"eL7tYgxhYh",
"imageSrc":"/Common/CaptchaImage/**eL7tYgxhYh**?t=636573960197174426"
}
How I can get a random value string "eL7tYgxhYh" in href by JSON Path Extractor with JMeter?
You cannot achieve this using JSON Extractor as it can only deal with JSON Objects, i.e. you can easily get full value of the imageSrc attribute, but not more.
I would recommend switching to Boundary Extractor instead, the relevant configuration would be something like:
Name of created variable: anything meaningful, i.e. href
Left Boundary: CaptchaImage/
Right Boundary: ?
That's it, the "interesting" value should be now extracted and you should be able to refer it as ${href} where required
Demo:

JSON format is in key-value pair so you just need to mention the key for which you need to extract the value. As in your case, you can use following JSON path expression for fetching the text mentioned by you:
$.sessionName
You can also use regular expression extractor which is another most important element of JMeter to extract the dynamic variables. Please refer to below blog of RedLine13 for more information on Regular Expressions:
https://www.redline13.com/blog/2016/01/jmeter-extract-and-re-use-as-variable/
Let me know if you have any further question
Above figure shows how to access access_token response of json and store it in access_token variable. In your case need to replace below.
JSONPath Expression use
$..sessionName
Destination variable Name
SessionName

To Get "636573960197174426"
To get required string from result string you can use BeanShell Assertion to split the string.

To Fetch jmeter Elements
I've the following URL
https://x.x.x.x/x/continue?processId=1234567&formAction=register
I need to extract the proccessId to use in the following request, but in JMeter with XPATH extractor value
//*[#id="signupForm"]
I can't recover the value, is there any option to solve it?
Easier to use Regular Expression Extractor for fetching value from URL
Add as a Post Processor of request Regular Expression Extractor with values:
Regular Expression: `processId=(\d+)&formAction=register`
Template `$1$` (indicate first group)
Match No. `1` ( fetch the first number)
Reference Name: `yourVariableName`
and then use ${yourVariableName} in your next request(s).
Note: If you are extracting from Request's URL you need to choose URL in Field to Check radio buttons.
In my application while executing the first request one unique key is generated which key is required for Next all the request. let me how to automate such scenario in Jmeter.
The process should look as follows:
Add Post Processor to the first request
Configure it to extract the required value and store it into a JMeter Variable
Use JMeter Variable from step 2 in your next request.
Depending on response data type you have the following choices:
Regular Expression Extractor - for text
CSS/JQuery Extractor - for HTML
XPath Extractor - for XML and XHTML
JSON Path Extractor - for JSON
It is also possible to extract data from files i.e. if response is in PDF format, but it's a little bit tricky
Example configuration to store the whole response:
Reference Name: any suitable variable name, i.e. response
Regular Expression: (?s)(^.*)
Template: $1$
You can refer the extracted value as ${response} where required. You can also amend the regular expression to extract response part instead of the whole response. JMeter uses Perl5-compatible regular expressions, see Regular Expressions User Manual Chapter for details
You can use regular expression extractor to extract the key from the response of your first request and use the extracted key for subsequent requests. To achieve this:
Right click on the first request and add post processor: Regular Expression Extractor.
Create your regular expression and provide values in other required fields. Please refer to JMeter component reference http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
Extracted value will be saved in the variable given as reference name
Use this variable in subsequent requests
Here is an example test plan with results.
