Ace editor 'named entity expected got none' error

Question

I was using ace editor to write some code, but when wrote & in a URL the editor gave me this error: named entity expected got none. I tried everything I knew about: changing & to &, & to %26, but nothing worked. Here's what I wrote:

<link href="https://fonts.googleapis.com/css2?family=Xanh+Mono&display=swap" rel="stylesheet">

Does anybody know what to do?

Answer 1

replace each & character with this &
