render a html string as a normal string in golang

here is my string :

test1 = `<iframe src="https:\/\/www.disnei.com\/embed\/44bc40f3bc04f65b7a35" frameborder="0" width="560" height="340" scrolling="no" allowfullscreen><\/iframe>`

and i would like to have the 'normal' string as :

<iframe src="https://www.disnei.com/embed/44bc40f3bc04f65b7a35"

etc ...

is there a simple way to do it in golang ?

Edit :
Here are some of my tests : https://play.golang.org/p/OuzNrTXYRB
I still have a blackslash plague

thanks and regards

you can use UnescapeString from the go html lib:
