How to extract JSON path separately?

I'm new to the JSON and I'm wondering how to extract a path from this kind of URL- https://www.example.com/bio-chocolate-p952 separately this way: product - bio-chocolate; product_id: p952 All I was able to come up with is following JSON pattern, which extract the path together:

{
    "v": 7,
    "domain": "example.com",
    "path.list": [
        {
        "$regex": "[a-z0-9-]+-[p0-9]{1,}",
        "extract": "product"
        }
    ]
}

Hopefully I made myself clear. Anyways thank you for your answers and time.

Have a nice day.
