I have an asp.net web page that has a TinyMCE box. Users can format text and send the HTML to be stored in a database.

On the server, I would like to take strip the h

If you are just storing text for indexing then you probably want to do a bit more than just remove the HTML, such as ignoring stop-words and removing words shorter than (say) 3 characters. However, a simple tag and stripper I once wrote goes something like this:

    public static string StripTags(string value)
    {
        if (value == null)
            return string.Empty;

        string pattern = @"&.{1,8};";
        value = Regex.Replace(value, pattern, " ");
        pattern = @"<(.|\n)*?>";
        return Regex.Replace(value, pattern, string.Empty);
    }

It's old and I'm sure it can be optimised (perhaps using a compiled reg-ex?). But it does work and may help...

You can use something like this

string strwithouthtmltag;    
strwithouthtmltag = Regex.Replace(strWithHTMLTags, "<[^>]*>", string.Empty)

Answer 3

TextReader tr = new StreamReader(@"Filepath");
string str = tr.ReadToEnd();     
str= Regex.Replace(str,"<(.|\n)*?>", string.Empty);

but you need to have a namespace referenced i.e:

system.text.RegularExpressions

only take this logic for your website
