Using scraped text in another xpath/regex/processors

[Boy Sandy Gladies Arriezona]

Hi, I want to scrape this json response:

{
      "id": "129460001",
      "fields": {
        "vendor_alias": [
          "unicorner"
        ],
        "item_min_qty": [
          "1"
        ],
        "vendors_min_array": [
          "1"
        ],
        "vendor_default": [
          "Unicorner"
        ],
        "vendors_stock_array": [
          "5"
        ],
        "item_default": [
          "60090"
        ],
        "vendors_price_array": [
          "93800.00"
        ],
        "item_name": [
          "Baseus Sky Case For iPhone 7 Transparent"
        ],
        "vendors": [
          "Unicorner"
        ],
        "item_image_url": [
          "assets/img/Libraries/img-86714-1599-sky-case-for-iphone-7-transparent.jpg"
        ],
        "item_alias": [
          "baseus-sky-case-for-iphone-7-transparent-129460001"
        ],
        "item_rating": [
          "0"
        ],
        "vendors_discount_array": [
          "0"
        ],
        "vendors_item_array": [
          "60090"
        ],
        "vendors_id_array": [
          "10854"
        ],
        "brand_id": [
          "1599"
        ],
        "item_min_discount": [
          "0"
        ],
        "item_stock": [
          "5"
        ],
        "item_min_price": [
          "93800"
        ],
        "vendor_default_id": [
          "10854"
        ]
      }
    }

My problem is when I try to get the url for this item. I should manually combine several json key with string because there is not any key which told me the exact url for this item. This is the example:
base_url + "v" + vendor_alias + "product" + item_alias




I can hardcode the base_url with static processor, but vendor_alias is relative to this items. Is it possible to do this kind of thing in DDS?

Not sure, if this solves your problem, but maybe have a look at attribute placeholders:

Holger i have same problem cause attrib placeholders are supporting  inside form data.
Is it possible we have attrib placeholders inside form data or another way to achieve it?
