I'm having issue with extracting GUID from location in header. I tried following and it doesn't seems to extract at all.
Response headers:
HTTP/1.1 201 Created
Content-Length: 99
Content-Type: application/json; charset=utf-8
Location: https://hello.com/books/category/cdeacb91af9f4faca842714c4ee9be45
Server: Microsoft-IIS/8.5
X-Powered-By: ASP.NET
Date: Thu, 05 Mar 2015 22:29:37 GMT
I tried with regular expression and it just won't extract that GUID. In most scenarios, I was able to extract whatever I want with (.+?)
Location: https://hello.com/books/category/(?s)(.*?)$
Location: https://hello.com/books/category/(.+?)
Thanks.
You can simply use a character class:
Location: https://hello.com/books/category/([0-9a-fA-F]{32})
[0-9a-fA-F] means all digits and letters between A and F, both upper and lowercase.
Your (.+?) regex will work fine if there will be right boundary provided.
Try changing it to
Location: https://hello.com/books/category/(.*)
It should do the trick
Also don't forget to change "Field to check" to "Response Headers" as regex will fail to lookup the "Location" header in the response body.

I am trying to extract the location from a POST in jmeter using the Regex Expression Extractor. The header looks like the below
HTTP/1.1 201 Created
Transfer-Encoding: chunked
groopId: ID-99-Inc-07-12300-2650126876118-1-236
User-Agent: RestClient-Tool
Date: Thu, 14 Feb 2019 13:57:23 GMT
Location: v2/TestData/12sff-13343e-dff3444455
Content-Type: text/plain; charset=UTF-8
I need theLocation: v2/TestData/12sff-13343e-dff3444455 .
I am struggling because I am not quite sure how to create the regex I need.
Add Regular Expression Extractor as a child of the request which returns above headers
Configure it as follows:
Apply to: depending on where this Location header comes from
Field to check: Response Headers
Regular Expression: Location: (.*)
Template: $1$
That's it, you should be able to access the extracted value as ${location} where required.

I am trying to replace everything that does not match the specified string. This would be I wish I could to a Match or something like that but I am sadly working in a software that only allows me to do regex calls within their replace function
For example, my string will be formatted like this:
HTTP/1.1 200 OK
Date: Wed, 12 Dec 2018 20:51:23 GMT
Server: Apache
x-request-id: eb6cf28d-fad9-42e2-ac3d-4efcf66c5f9b
ETag: 83705a06-4562-4bbd-bcbe-c7643d2d6008
Content-Length: 531
Strict-Transport-Security: max-age=31536000;
X-XSS-Protection: 1; mode=block
X-Content-Type-Options: nosniff
X-Robots-Tag: none
P3P: CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"
Keep-Alive: timeout=15, max=200
Connection: Keep-Alive
Content-Type: application/json;charset=UTF-8
I need to remove everything that does not match
ETag: 83705a06-4562-4bbd-bcbe-c7643d2d6008
I have written some regex that selects ETag: 83705a06-4562-4bbd-bcbe-c7643d2d6008 that looks like (ETag: [a-zA-Z\d.-]*)
And this does select that line, but I need to replace everything but that line. I have read a few post that asked suggested to do the following:
^(ETag: [a-zA-Z\d.-]*)
(?:(ETag: [a-zA-Z\d.-]*))
(ETag: [a-zA-Z\d.-]*)[^]
None of those seemed to work I have a sample of this running on RegExr
Once again, I need to replace everything that does not match ETag: GUID. I would appreciate any help in doing this. I am sure I am just missing something small.
Regex doesn't really have negation, but usually you can use negative lookaheads:
^(?!ETag: [a-zA-Z\d.-]*).*$
This matches the beginning of a line that can't match ETag:..., followed by the rest of the line. You can see how it works in this demo.
I'm trying to build a regex to match mutliple strings from an HTML response.
This is used to monitor a webpage from a load balancer. If the regex has a match, the load balancer will consider the server as UP and will send traffic.
Example of expected HTML response :
HTTP/1.1 200
X-AREQUESTID: *1KIRCWLx688x71065x0
X-XSS-Protection: 1; mode=block
X-FRAME-OPTIONS: SAMEORIGIN
X-Content-Type-Options: nosniff
Access-Control-Allow-Origin: *
Content-Type: application/json
Transfer-Encoding: chunked
Content-Encoding: gzip
Vary: Accept-Encoding

{"state":"RUNNING"}
What I want to achieve is trying to match {"state":"RUNNING"} OR {"state":"MAINTENANCE"} AND HTTP/1.1 200
So I have the following working regexes, but I don't know how to bundle them up together ;-)
\{\"state\":\"RUNNING\"\}|\{\"state\":\"MAINTENANCE\"\}
will match {"state":"RUNNING"} OR {"state":"MAINTENANCE"}
HTTP\/1\.(0|1) (200|301|302)
will match the HTTP response code 200, 301 or 302 (ex : HTTP/1.1 200)
So now, how do I build a mega regex will all conditions ?
HTTP\/1\.(0|1) (200|301|302) AND \{\"state\":\"RUNNING\"\}|\{\"state\":\"MAINTENANCE\"\} ?
Is it even possible?
Thanks in advance
This will do the trick:
/HTTP\/1\.(0|1) (200|301|302).*?(\{\"state\":\"RUNNING\"\}|\{\"state\":\"MAINTENANCE\"\})/s
The key in this version is the s flag, which allows . to match a newline (\n) character. Demo on regex101.
Another option, without using flags:
HTTP\/1\.(0|1) (200|301|302)[\s\S]*?(\{\"state\":\"RUNNING\"\}|\{\"state\":\"MAINTENANCE\"\})
The key is the [\s\S]*?, which matches literally anything (new lines included) in a non-greedy fashion. Demo on regex101.
Combining two regular expressions is done by simply concatenating them. If you want to allow arbitrary characters in between, use .* between them.
Assuming that your regular expressions match over the whole response including headers and body and not just single lines, the following should suffice.
HTTP\/1\.(0|1) (200|301|302)\r\n(.*?)(\{\"state\":\"RUNNING\"\}|\{\"state\":\"MAINTENANCE\"\})$
I have bellow response header that is giving me the problem when extracted using Regular Expression Extractor. To keep to story short, after troubleshooting I come up with a solution that works but is not perfect.
The Headers
Response headers:
HTTP/1.1 200 OK
Vary: Origin, Accept-Encoding
Access-Control-Allow-Credentials: true
X-XSS-Protection: 1; mode=block
X-Frame-Options: DENY
X-Download-Options: noopen
X-Content-Type-Options: nosniff
access-token: GAbnLmcDzT4j5INPkSGwdbQzZIIFIaJoy4wBnmNUF4NEgGB11IfzTAMdqXyxIhAZ
Access-Control-Expose-Headers: access-token
Content-Type: application/json; charset=utf-8
The Solution
Regular Expression : access-token: (.+?)\n
Template : $1$
Refer to below picture on why I think the solution is wrong.
Extracted token is represented by multiple variable as result_token, result_token_g, result_token_g0, result_token_g1:
The Question
What is the correct Regular expression and template to get only the token.
TIA!
UPDATE:
Bellow excerpt from Regular Expression Extractor Doc actually help me better understand this question.
If the match number is set to a negative number, then all the possible matches in the sampler data are processed. The variables are set as follows:
refName_matchNr - the number of matches found; could be 0
refName_n, where n = 1,2,3 etc - the strings as generated by the template
refName_n_gm, where m=0,1,2 - the groups for match n
refName - always set to the actual template value if a match is found, otherwise, the default value.
It seems to me, that you are getting it right; result-token_g1 contains the intended capture, and it is replicated via your template to result-token.
Don't worry about result-token_g0; it's supposed to show the complete match: capture AND context.
Use this:
Regular Expression : access-token: (.\w*)
Template: $1$
Match No: 1
DefaultValue: Not found
I'm trying to extract the confirmation number at the end of the location tag in the response header to a page using RegEx. The response header is as follows:
HTTP/1.1 302 Moved Temporarily
Date: Mon, 09 Sep 2013 17:55:50 GMT
Server: Apache-Coyote/1.1
Location: http://test.regtest.com/cart/confirmation?confirmationNumber=00284031
Content-Language: en
Content-Length: 0
X-Cnection: close
Content-Type: text/plain; charset=UTF-8
Vary: Accept-Encoding
For instance, if in the header the line is this:
Location: http://test.regtest.com/cart/confirmation?confirmationNumber=00284031
I am looking to return this to use as a variable later:
00284031
My current RegEx expression is something like this:
Location: http://test.regtest.com/cart/confirmation?confirmationNumber=(\d+)?
I am new to RegEx and what I wrote above is based off the example at the following link:
http://www.sourcepole.ch/2011/1/4/extracting-text-from-a-page-and-using-it-somewhere-else-in-jmeter
I need this confirmation number for a dynamic page redirect for a Jmeter script I am writing. Any help would be greatly appreciated and if you require additional information to help answer the question let me know!
Many thanks in advance.
Try this: Location: [\S]+?confirmationNumber=(\d+)
Your issue is the use of special characters in the string without escaping them - e.g.: ? and /
Note my ? is not matching the question mark in front of confirmationNumber, but instead is making the [\S]+ non-greedy.
If you want to be explicit, your version should work if modified like this to escape the characters with special meaning:
Location: http:\/\/test.regtest.com\/cart\/confirmation\?confirmationNumber=(\d+)?
You don't need to match the entire line to get the confirmation number, instead you can just match the number like this:
(?<=confirmationNumber=)(\d+)
(?<=confirmationNumber=) is called a look behind, what the expression says is to match one more digits (\d+) and put them into a group, only if those digits are preceded by the following string confirmationNumber=.

Regexp as following
confirmationNumber=([0-9]+)
