Issue with gsub method in my Ruby code when trying to replace HTML tags with the URL stripped from in it

I am trying to achieve a basic substitution but I am finding it difficult to determine the behaviour here.

I want to replace the tags with the URL contained inside it.

This is my code:

require 'nokogiri'    message = "Hi Testin wFAASF,  Thank you for booking with us.  Your work has been booked on Sep 16, 2020 1:00PM at 2026 South Clark Street / unit c / Chicago, Illinois 60616  Sincerely,  Varun Security  <a href=\"https://www.google.com\">Test This PR</a>"    puts message.gsub(Nokogiri::HTML.parse(message).at('a'), Nokogiri::HTML.parse(message).at('a')['href'])  

What I think the output would be:

"Hi Testin wFAASF,  Thank you for booking with us.  Your work has been booked on Sep 16, 2020 1:00PM at 2026 South Clark Street / unit c / Chicago, Illinois 60616  Sincerely,  Varun Security  https://www.google.com  

What the actual output is:

"Hi Testin wFAASF,  Thank you for booking with us.  Your work has been booked on Sep 16, 2020 1:00PM at 2026 South Clark Street / unit c / Chicago, Illinois 60616  Sincerely,  Varun Security  <a href=\"https://www.google.com\">https://www.google.com</a>"  

Could someone explain why this is happening and how I could do this better?
