Need Help with creating Dynamic Selectors

selector
studio

#1

Hello Everyone,
I am trying to create a DYNAMIC SELECTOR that will always click on the latest/ bottommost BPA text ( which has an attachment hyperlink) from the table. I have been trying for couple of hours and I seem lost now.
#The only clickable text is BPA
#Every time I generate a report the total number of records increases and my selector is not the bottommost anymore.
Someone help me… I have tried the wild cards and played around with selectors , still not working.

Hi @Pema_Sherpa,

You can do two ways.

  1. Using extract Structure data extract tha data and using row count you can get that the last number.

2.using find children activity get the last element and you can click that one.

Refer below path

Hi @Pema_Sherpa ,

Use find children activity to get the last element and click that one.

I just used the find children activity and used the same selectors code in the click activity after that, it still clicks on the old text when I run it the second time.

@Pema_Sherpa In find children activity get the last element and click it.

Hi @Pema_Sherpa,

Find children output -> innumerable

Assume as Children

Get the last element Children.last

Using click event pass the element as Children.last
