Is there an analogue of JSON schema (XML schema) validation, but for arbitrary text (except RegExp)?

Question

Validation

It is required to check the correctness of certain texts according to the parameters specified by the user.
For example, in the test there should be such and such words, but there should not be such and such. Such and such a word should be after some other.
Regular expressions are like that, but not quite. And it's complicated.
I don't want to reinvent my wheel.
