Remove HTML tags without REPLACE

Question

Hello,
I have a simple query that returns some data, but the result could have html tags. I don't want to keep using REPLACE because sometimes I receive a tag that is not included in the REPLACE function. Is there is a way to do that, may be using some XML code?
Thank you

With a CTE
like that 
ALTER FUNCTION dbo.fnHtmlStripFreeLight

@inputStringCleaned8 VARCHAR(MAX),@inputStringCleaned9 VARCHAR(MAX), @inputStringCleaned10 VARCHAR(MAX),@inputStringCleaned11 VARCHAR(MAX),
@inputStringCleaned12 VARCHAR(MAX),
