Actually I want to access an element Text(i.e. Friends) from https://www.facebook.com/groups/FAW.2011/[^] and write it to my form i.e. Form1 textBox1.Text;
for this purpose I write a code like mentioned below but could not access it.

string url="https://www.facebook.com/groups/FAW.2011/";

XmlDocument docs = new XmlDocument();
docs.LoadXml(url);

string name="Friends";
string show=Convert.ToString(docs.InnerText.Contains(name));
textBox1.Text=show;

Can anyone help me to modify so that I can access an element text (i.e. Friends) from the above mentioned url?
