How To Convert HTML to Text, Easily

7:12:00 am 0 Comments


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 <tags>, 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>

   {


   }
   public string StripTags(string HTML)
   {
       // Removes tags from passed HTML 
       return System.Text.RegularExpressions.Regex.Replace(HTML, "<[^>]*>", "");
   }


   protected void Button1_Click(object sender, EventArgs e)
   {
       Label1.Text = StripTags(TextBox1.Text);

   }
}
