How to Remove HTML Tags from a String Using C# Regular Expressions?

Efficiently Removing HTML Tags from C# Strings

Cleaning text data by removing HTML tags is a frequent requirement in many C# applications. While regular expressions offer a concise solution, they might not always be the most robust method, especially when dealing with complex HTML structures.

A simple regular expression to remove HTML tags is:

<[^>]*>

This expression identifies and matches any characters enclosed within angle brackets, effectively targeting HTML tags. The Regex.Replace method then facilitates the removal:

string cleanText = Regex.Replace(htmlString, @"<[^>]*>", string.Empty);

This code snippet replaces all matched tags with an empty string, leaving only the plain text.

Important Considerations:

This regex approach has limitations. It might fail to correctly handle scenarios involving nested tags or CDATA sections containing angle brackets. For more complex HTML, a dedicated HTML parser offers superior accuracy and reliability. Using an XML parser is a better alternative for robust HTML tag removal in such situations.
