Hi, the problem exists due to the dynamic nature of the page, you can maybe go about defining selectors but I don't think that will solve your problem.
the easiest solution that I can think of is by using extracting the details as a datatable. Here is how you can do it:
1) Scrape the web page for table format
2) Extract the data as a data table
3) From that datatable go to the link and just open the link using the URL obtained or use the URL with 'attach browser' activity to download the content.
