How to make json-edit match when property name is either X or Y?

[Stevoisiak]

I want to make a filter with json-edit-fetch-response where the one part of the JSONPath expression can match either of two different property names

For example, I have two filter rules for illust and novel items:

pixiv.net##+js(json-edit-fetch-response, $..illust.[?.aiType==2])
pixiv.net##+js(json-edit-fetch-response, $..novel.[?.aiType==2])

Is it possible to combine them into a single rule? Something like:

pixiv.net##+js(json-edit-fetch-response, $..(illust|novel).[?.aiType==2])

---

Example input JSON:

{
  "body": {
    "illust": [
      {
        "id": "146106838",
        "aiType": 2
      },
      {
        "id": "146136343",
        "aiType": 1
      }
    ],
    "novel": [
      {
        "id": "24319529",
        "aiType": 2
      }
    ],
    "other": [
      {
        "id": "123456789",
        "aiType": 2
      }
    ]
  }
}

Example output JSON:

{
  "body": {
    "illust": [
      {
        "id": "146136343",
        "aiType": 1
      }
    ],
    "novel": [],
    "other": [
      {
        "id": "123456789",
        "aiType": 2
      }
    ]
  }
}

(This was originally asked on r/uBlockOrigin, but I was told to ask here instead)

This should work (RFC9535-conform -- works at jSONPath Online Evaluator):

$..['illust','novel'][?@.aiType==2]

[Stevoisiak]

That works in the JSONPath tool, but when applied to a filter the logger says it's a bad JSONPath.

www.pixiv.net##+js(json-edit-fetch-response, $..['illust','novel'][?@.aiType==2])

[gorhill]

You need to quote the query since it contains commas, this should work:

www.pixiv.net##+js(json-edit-fetch-response, "$..['illust','novel'][?@.aiType==2]")

[Stevoisiak]

That worked perfectly.

On a related note, does uBO support "equals X or Y" for values? The pattern below worked in the JSONPath evaluator but not uBO's JSONPath tool.

$..illust[?@.aiType==1 || @.aiType==2]

[gorhill]

From uBO flavored JSONPath:

Not supported:

• ...
• Selectors with logical operators: $.o[?@.u || @.x], $.o[?@>1 && @<4]
  ...

However as a workaround you could use the uBOL-specific operator =/.../:

$..illust[?@.aiType=/^[12]$/]

The reason logical operators are not implemented is because I am waiting for actual need in real world cases since I want to keep the implementation as small as possible since the JSONPath code needs to be injected in webpages where it's required -- I feel like supporting || and && would add quite a bit of code to the implementation.
