public static string RemoveHtmlTag (string source)
{
int debut;
int fin;
string theTag;

debut = source.IndexOf("<");
fin = source.IndexOf(">");

while ((debut >= 0) && (fin > 0))
{
debut = source.IndexOf("<");
fin = source.IndexOf(">");
if (debut >= fin)
{
debut = 0;
}
fin = fin - debut;
theTag = source.Substring (debut, fin + 1);
if (theTag != "")
{
source = source.Replace (theTag,"");
}
}

source = source.Replace("&nbsp;", " ");
source = source.Replace("&gt;", ">");
source = source.Replace("&amp;", "&"); // Trim
return source;
}
