Whether you want to convert an HTML page into pure text so you can parse out that special piece of information, or you simply want to load a page from the Net into your own word processing package, this mini function could come in handy.
It’s called StripTags and accepts an HTML string. Using a regular expression, it identifies all, removes them, and returns the modified string. Here’s the code:
<%@ Page Language="C#" ValidateRequest="False" AutoEventWireup="true" CodeFile="StripTag.aspx.cs"
Inherits="StripTag" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" Height="172px" Width="363px" TextMode="MultiLine"></asp:TextBox></div>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</form>
</body>
</html>
