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.

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
As I am new in using jmeter I'm stuck to write regular expression for this expression:
/catalog/search_display?category_id=9">Parts</a>
Can somebody help me out.
/catalog/search_display\?category_id=9">Parts</a>
Is that what you need? The question mark needs to be escaped, I don't see anything else noteworthy about it. The JMeter regexes are not enclosed in // and thus the slash is not a special character.
What do you want to extract? I assume that it is 9 (category_id). In that case regular expression extractor configuration should look like:
Reference Name: anything meaningful, i.e. id
Regular Expression: <a href="/catalog/search_display\?category_id=(.+?)"
Template: $1$
Refer extracted value as ${id} where required.
Mention that question mark needs to be escaped by a back slash as it is reserved character in regular expressions.
See Regular Expressions chapter of JMeter's User Manual for Perl5-style regex syntax and examples.
Also be aware that it isn't very recommended to parse HTML using regular expressions and it might be better to use the following post processors instead:
CSS/JQuery Extractor
XPath Extractor
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+)

How do I get data from below service response using regular expression extractor in Jmeter?
Extract token ID:
<ValidateUserResponse xmlns="http://tempuri.org/"><ValidateUserResult xmlns:a="http://schemas.datacontract.org/2004/07/ISOS.Medtrack.Mobile.Entity" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><a:ErrorKey i:nil="true"/><a:ErrorMessage i:nil="true"/><a:SystemId>0</a:SystemId><a:Type>0</a:Type><a:status>SUCCESS</a:status><a:IsAuthenticated>true</a:IsAuthenticated><a:IsDashboardLanding>true</a:IsDashboardLanding><a:IsEmployee>true</a:IsEmployee><a:IsMobileAppEnabled>true</a:IsMobileAppEnabled><a:IsPwdChgRqd>false</a:IsPwdChgRqd><*a:TokenID>**9de2dbfbcc94241002f57275e8dc78e60f26baabc05c1eebe39088d02e6e454f***</a:TokenID><a:UserStatus>ACTIVE</a:UserStatus></ValidateUserResult></ValidateUserResponse>
Theoretically you can do it with regular expressions, however I would rather go for XPath Extractor for dealing with XML data instead.
Follow the next steps to extract your TokenID value:
Add the following line to user.properties file (lives under /bin folder of your JMeter installation)
xpath.namespace.config=my.properties
Create "my.properties" file in the same location and add next 2 lines there:
a=http://schemas.datacontract.org/2004/07/ISOS.Medtrack.Mobile.Entity
i=http://www.w3.org/2001/XMLSchema-instance
Restart JMeter
Add XPath Extractor as a child of the request which returns that XML
Configure the XPath Extractor as follows:
Check "Use Namespaces" box
Put //a:TokenID/text() line into "XPath Query" input
Set "Reference Name" to something meaningful, i.e. TokenID
You should be able to access extracted value as ${TokenID} after XPath Extractor execution.
Hope this helps.
Though Regex should not be used in XML cases as it is a bad practice.
but XPath Extractor should be avoided in actual performance tests because they are heavy in nature as compared to Regex.
XPath builds a DOM tree so it consumes CPU and memory and you might run out of memory or overload CPU during performance tests which in turn could result in invalid results. Thus prefer Regular Expression extractor whenever possible.
Simple Regex expression could be,
TokenID>\*\*(\w+)\*\*\*
extracted value can be used as $1$.
The best way to solve the problem with namespaces in XPath Extractor, that simple use the impruved iXpath (improved jmeter xpath plugins)
