How do i select all text on a page

How to?
#1

Hi

I am trying to select all the text from a single page because the destinations are different and a singular 'map' won't work for each destination, Instead how do I select text for the entire page?

Thanks

@NeilGriffiths Hello, could you, please, provide us with the targeted website?

In any case - normally that should be possible by using the 'html' or 'body' selectors unless this data is embedded into an iframe or shadow root.
