How to select all to copy when on a webpage

iOS and iPadOS

I am using an iPad Air 1 and IOS 9.1. I bought Voice Dream Reader and see that I can paste the contents of a web page into the app and let the app read it to me. But using Safari I can not figure out how to select everything on a web page. I have put the rotor on text selection, flicked to select all, double tap, then put the rotor on edit and flicked to copy and double tap. When I paste I only get a few lines. can anyone tell me how to select all and copy everything on a web page?
