int len=Source.Length;
string title=" ";
char c;
for(int i=0;i<len;i++)
{
c=Convert.ToChar(Source.Substring(i,1));
title=title.Remove(0,1);
title+=c;
if(title.ToLower()=="<title")
{
while(c!='>')
{
i++;
c=Convert.ToChar(Source.Substring(i,1));
}
title="";
i++;
c=Convert.ToChar(Source.Substring(i,1));
while(c!='<')
