Recognize empty holes, and add them as "null"

How to?
#1

Hello!

I try to capture the "quantity" section in a grouped form.
For later in the excel you can modify it like this: 1,1,1,2,1,5,4,6

But in the sections that there is no quantity, it does not capture anything, so it does not fit me.

For example in this link: https://www.bike-parts-honda.es/honda-motocicleta/50-MOTO/CB/1998/CB50V/Chasis/EMBLEMA-FLEJE/95120/F_32/2/33204

I would need the result to come out like this for example
[{"quantity":"","quantity-value":"null"}{"quantity":"","quantity-value":"null"}{"quantity":"","quantity-value" :"1"},{"quantity":"","quantity-value":"1"},{"quantity":"","quantity-value":"1"},{"quantity":" ","amount-value":"1"}{"amount":"","amount-value":"null"}]

But the result gives me:
[{"quantity":"","quantity-value":"1"},{"quantity":"","quantity-value":"1"},{"quantity":"","quantity- value":"1"},{"amount":"","amount-value":"1"}]

So then I can put "null" as "1" and it fits me well.

I have this:

Sitemap:
{"id":"quantity","parentSelectors":["partspare"],"type":"SelectorGroup","selector":"input.text-center[name="qte_table_parts"]","delay ":0,"extractAttribute":"value"}

Is there a way? Thank you! Thank you! Thank you!

@ElTucu Hi, that is possible to be done using an 'Element' selector in a combination with 'Element attribute' selector.

Example:

{"_id":"bike-parts-honda-es","startUrl":["https://www.bike-parts-honda.es/honda-motocicleta/50-MOTO/CB/1998/CB50V/Chasis/EMBLEMA-FLEJE/95120/F_32/2/33204"],"selectors":[{"delay":0,"extractAttribute":"value","id":"value","multiple":false,"parentSelectors":["wrapper"],"selector":"input.text-center[name=\"qte_table_parts\"]","type":"SelectorElementAttribute"},{"delay":0,"id":"wrapper","multiple":true,"parentSelectors":["_root"],"selector":"tr[itemtype='http://schema.org/Product']","type":"SelectorElement"}]}
