Take for example we wanted to extract links from a google search “amazon”
But we want to not only take this link but all the links on the first page.
To get the format format for the dynamic selector we would get the selector for the first item as follows
Then we use an assign activity and create a string variable dynamic Selector (or any other name that makes sense for your workflows)
and on the other side we want to make it dynamic by changing the aaname to a variable (this can be done for any part of the selector depending on your needs)
This allows for dynamic changing of different pieces of our selector
In your case you could screen scrape the structured data into a datatable and then create a for loop where it left clicks on each element and gets the data and places it into another column of your datatable. Iterate through the existing data table and replace the dynamic selector each time with the next item in your table. Just a simple example, if you have any another questions or need more clarification let me know!
