In your case, you are fetching the data from a website, and using that as a "path" to a file.

So the illegal characters are part of the data you fetched from the site, and beyond our - or your - control.
The chances are that the data you have fetched is not a valid path at all - it's probably XML or HTML data.
So use the debugger, look at exactly what you are fecting and see what the data actually is. Then you can start deciding what is and isn't a "legal character" in your path.

Hi Athul,
XDocument Do not have any suitable method which can take whole xml string as input and load that xml. It have only method in which you have to pass URL of the source.

Please see the screen shot.

is it possible to pass the URL source in Xdocument

Yes you can pass URL("http://www.ft.com/rss/home/us") directly but you can not pass your header key
wc.Headers.Add("user-agent", "Mozilla/5.0 (Windows; Windows NT 5.1; rv:1.9.2.4) Gecko/20100611 Firefox/3.6.4");
So it will give you error like Unauthorized access or Forbidden.

C#

string illegal = "\"M\"\\a/ry/ h**ad:>> a\\/:*?\"| li*tt|le|| la\"mb.?";
string invalid = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());

foreach (char c in invalid)
{
    illegal = illegal.Replace(c.ToString(), "");
}
