Better yet, use S-Expressions.
There are tons of parsers available.
markup is simple:
(this_is_the_tag
this is all data
(except_this_is_a_nested_tag with still more data))

Even better still, there are customizable parsers available that can treat these S-Expression as data OR interpret them as program OR a combination of both. One such parser is called "Lisp". Once again, several implementations are available.
Note that things like S-Expressions and Lisp have only been around for 40 years so you might want to give these technologies some time to mature.
