Hi Eddy,
thank you for responding to my question - unfortunately that didn't solve my Problem or provide a solution.
Subborn as i am i couldn't leave the topic alone and i finally found the explanation/solution on my own:
First: PAD Workflows differ concerning variable notation, depending if Power FX is activated or not.
The Web Data Extract connector always creates a data table object, even if only a single value is extracted (as for example an innerHTML of a div element). Even when a list of entries is extracted - like the link list in my original post - the generated object is always a data table, not a data list object.
To directly access the values it's necessary to double index the query as in 2-dimensional arrays.
Given the extracted data was saved in the default variable DataFromWebPage and no foreach loop is used:
Without Power FX
%DataFromWebPage[0][0]%
With Power FX
=Index(Index(DataFromWebPage, 1), 1)
Accordingly when using a foreach loop on the DataFromWebPage object (which of course creates a data list object, default name is CurrentItem):
Without Power FX
%CurrentItem[0]%
With Power FX:
=Index(CurrentItem, 1)
Hopefully this will help other new Power Automate'rs saving valuable time on this topic.
TGF, have a nice weekend & Best Regards
Oliver
