What is your personal definition of a tag?
To match a tag, you could use "/<[^>]*>/" but that would also match
"<>".
Maybe you are just looking for "/<[A-Za-z]+>/"?

And that is what you should expect when you use the wrong tool, or use a
tool in the wrong way.
You are not matching tags there, but constructs delimited by tags. That
is much easier to do with multiple passes. Use a parser. It is often
simple to create one.

Don't focus on "an expression", your toolbox is bigger than that.
my $atom = qr~<([a-z]+)>[^<>]+</\1>~; # meant to evolve ;-)

That is very stupid.
