Replace all HTML tags from text/string

Introduction

This tip shows you how to replace HTML tags from text/string using Regular expression.

Using the Code

Pass text/string to input variable. The regular expression will remove HTML tags like <p>, </p>, <body>, </div>, etc. This is case insensitive.

string input = "<b>This is test.</b><p> Enter any text.</p><div> The place is really beautiful.</div><img src=''>";

//To remove tags which are without any attribute
string str1 = Regex.Replace(input, @"(\<(\/)?(\w)*(\d)?\>)", string.Empty);

//To remove all kind of tags -- suggested by codeproject member 'svella'
string str2 = Regex.Replace(input, @"<.*?>", string.Empty);

Console.WriteLine(str1);
Console.WriteLine(str2);
Console.ReadLine();

Points of Interest

Less code compared to string.Replace(), less maintenance.
Even if tomorrow new HTML tags come or it can even remove 3^rdparty tags which follow HTML tag kind of syntax
