Ensure that a variable adheres to the standards of a proper HTML template

I'm struggling with a problem in my Angular application. I need to ensure that a TypeScript variable is a valid HTML template to compile successfully, like this:

let v = '<div>bla…</div>'

However, if the variable contains incorrect HTML syntax like this:

let v = '<cc></div>'

it will result in a compilation error. Is there any way to enforce this requirement?

Update:

If it's not possible to check at compile time, is there a way to make the Angular Cli Builder fail during build when encountering such errors?

Is it feasible to validate html strings during compilation?

If you are interested in assessing the validity of html during runtime, you may find this resource helpful: Check if HTML snippet is valid with JavaScript

Depending on your specific requirements, you may also have to sanitize html content or skip the sanitizer altogether by utilizing https://angular.io/api/platform-browser/DomSanitizer
