Download a file form a web page IF is verify a specific condition

Hello to everyone,
I’m setting a sequence that have the function to download invoice received only IF is verify a data condition that the user can type into a box message before the download.
For example IF the column “Data ricezione” is equal to the data into the box message (typed by the user), so click in XML to download the file and save it in a specific path.

I’m a beginner and for me is difficult figure out how can i do this action for all the row in the page (for all the invoice)

Somone could help me in setting the sequence?
TKS you so MUCH!
