Converting html anchors to markdown using sed regex

I've been slowly converting a blog of mine to markdown. The final thing to do is replacing all the html anchors with markdown. I've come up this sed regex, which for all intents and purposes should do what I want, but it doesn't. Source data: $ cat /tmp/test on reddit or Lifehacker Sed command: $ sed -r 's/(.*?)/[\2](\1)/g' /tmp/test on [Lifehacker](https://lifehacker.com/ " target="_blank" rel="noopener) What I want it to return: on [Reddit](https://reddit.com/) or [Lifehacker](https://lifehacker.com/ ")
