I need ideas on how to enter these elements in turn.
Suppose I select the first element, a window opens in it, I compare the data and save, if the data is correct, then this element disappears (from the list in the picture)
If that’s the case you will have to try Full Text Screen Scraping (or the find child activity). Also, you will need knowledge of dynamic selectors to click on each item in the table. If you look at the selector code, you will probably find part of the first selector has a “0” or “1” and you would usually replace that number with a counter variable mentioned above.
So your steps will be data extraction (via screen scraping or other method) > Loop through the table it creates > in iteration instance of your loop you will put your processing code, whatever that may be.
