Open-source nhtmlfilter helps you filter HTML dangerous scripts to prevent XSS attacks

Have you been worried about how to prevent XSS attacks? Try nhtmlfilter. I think it is what you want ..

Recently, a new small company is very weak in. NET web development. The underlying framework and basic library are not perfect. It is also an Internet application, so security always needs to be considered. One small problem I want to solve today is to filter out the scripts in the HTML text uploaded by the user. I checked on the Internet and found no suitable C #-based processing. In Java projects, I may choose jsoup, htmlfilter to deal with HTML dangerous scripts (in fact, I used to do Java Development). In desperation, I will refer to the htmlfilter of Java version.CodeWrite the C # version.

Usage

 
Nhtmlfilter target = new nhtmlfilter (); string input = "<div> DD </div> <a id = \" testid \ "href = \" http://code.google.com/p/nhtmlfilter\ "> nhtmlfilter </a> "; string expected = "DD <a href = \" http://code.google.com/p/nhtmlfilter\ "> nhtmlfilter </a>"; string actual; actual = target. filter (input );
