JS Regex to check that string only includes anchor

Question

I am trying to create a regex that will return true only when the string only contains an anchor like so <a href="www.something.com">Link</a> .

Currently I have the following regex which almost works (?=.*^<a)(?=.*<\\/a>).*/g

This works for the following scenarios:

<a href="www.something.com">Link</a> - Matches successfully

words before <a href="www.something.com">Link</a> - No matches - success

<a href="www.something.com">Link</a> words after - finds match - Not successful :(

I think I'm pretty close, I just need to know how to not find a match if there are any characters after the </a> .

Answer 1

Add a $ after the last >

(?=.*^<a)(?=.*<\\/a>$).*

Alternatively, this regex matches links and discards everything else, irregardless of whether there are one or more links in the same line.

<a.*?\\/a>
