How to Split value in Jmeter from Response?

Question

I am new to JMeter. I want to extract and Split response. Here is the response,

{
   "totalDocs":3,
   "recordBatchSize":10,
   "listingType":1,
   "currentPageNo":1,
   "recordStartFrom":0,
   "data":[
      {
         "fileType":"filetype/pdf.gif",
         "issueNo":1,
         "revisionId":"123456$$kWGFhP",
      },
      {
         "fileType":"filetype/pdf.gif",
         "issueNo":1,
         "revisionId":"222222$$kFMFhP",
      },
      {
         "fileType":"filetype/pdf.gif",
         "issueNo":1,
         "revisionId":"333333$$kYEGhP",
      }
   ],
   "viewType":"listing",
   "sortFieldType":"timestamp",
   "isIncludeSubFolder":true,
   "totalListData":0
}

I want to extract revisionId and split numbers ie 123456, 222222, 333333

Also please share where in JMeter I extract this value? Using Regular Expression Extractor Or JSR223 Post Processor, I am new to both.

I've tried with "revisionId"\s*:\s*"(\d+) (Which @Dmitri T suggested) but it passes variable name in the request ie ${ref_paramrevisionId1}. see attached image.

Answer 1

I think the easiest would be going for the Regular Expression Extractor, the following regular expression should extract the numbers you're looking for:

"revisionId"\s*:\s*"(\d+)

Explanation:

• \s* - matches an arbitrary number of whitespaces
• \d+ - matches an arbitrary number of digits
