Jayway jsonpath starting with “/” in regex

Question

I am having issues with jayway jsonpath when it comes to using regex which has xpath in it. Here is my json:

{
  "status": "success",
  "resources": [
    {
      "id": "Attachment-20796b26-7a16-4a3d-b53c-b30d9f3cb798.TXT",
      "name": "1996032897__test1.CREDITPRINTFILE",
      "mimeType": "text/plain",
      "url": "https://test.com"
    }
  ]
}

Here is my expression: resources[?(/__test1.CREDITPRINTFILE/.test(@.name))]

I am getting the below error:

I tried using the same expression in online evaluation tools as well: https://jsonpath.herokuapp.com/

Jayway - gives the same error - Expected path node Gatling, Nebhale - errors out Goessner - gives me the valid result

I am using the latest version of jayway i think -

<dependency>
  <groupId>com.jayway.jsonpath</groupId>
  <artifactId>json-path</artifactId>
  <version>2.4.0</version>
</dependency>

Question: If jayway does not solve these kind of expressions, is there any other java library which can be used to solve these?

Answer 1

Assuming you are looking for the "resource whose name contains __test1.CREDITPRINTFILE ", the jsonpath expression resources[?(@.name =~ /.*__test1\\.CREDITPRINTFILE/)] will work with Jayway. Tested at https://jsonpath.herokuapp.com/
