Eliminate the JavaScript code from within the HTML document

Need help with a C# regular expression to remove JavaScript from HTML. Can anyone assist me in writing the code?

Answer №1

Simply removing the <script> tags is not enough to prevent Javascript execution. Event handlers like onclick can still execute harmful code, making it difficult to filter out using regular expressions.

This recurring problem highlights the inefficiency of parsing HTML with regular expressions. To ensure stability in your code, it's crucial to utilize an HTML parser instead.
