ASP.NET C# -STRING PROCESSING

hello everyone
currently i am doing a project on XSS(Cross Site Scripting) prevention, for that i want to process a small text paragraph, contain text and java code.
example-
The Conjuring 2 is a mixed bag of a movie.....That being said, if you are someone that doesn't mind jump scares, you will most likely eat this movie up!<..........some java code here...........>

i want to separate out the text code present in between "<" and ">" so that i can process it separately.

thank you for your help.
