Continuing to play with the twitter API. See Part Un.
Last couple days, I made a new C# program to find ppl I'm following on Twitter that didn't follow me back. I, of course, unfollowed them.
I had to cache my friends XML, since the 150 call per hour rate limit, made it impossible to run once. The code follows. Hope you like and re-use.
static string userid = "137692493";
static void FindNoFollows()
{
string s = string.Format("https://api.twitter.com/1/friends/ids.xml?screen_name={0}", "talkSportscom");
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
if (!System.IO.File.Exists("ids.xml"))
{
doc.Load(s);
}
else
{
doc.Load("ids.xml");
}
foreach (System.Xml.XmlElement e in doc.SelectNodes("//id"))
{
try
{
if (e.HasAttribute("done"))
{
continue;
}
e.SetAttribute("done", "true");
doc.Save("ids.xml");
// need to sleep 30 seconds between calls to avoid 150 rate limit per hour
//System.Threading.Thread.Sleep(30 * 1000);
s = string.Format("https://api.twitter.com/1/friends/ids.xml?user_id={0}", e.InnerText);
System.Xml.XmlDocument d = new System.Xml.XmlDocument();
d.Load(s);
System.Console.WriteLine(d.OuterXml);
System.Xml.XmlElement dt = (System.Xml.XmlElement)d.SelectSingleNode(
string.Format("//id[text()='{0}']", userid));
if (dt != null)
{
continue;
}
s = string.Format("https://api.twitter.com/1/users/lookup.xml?user_id={0}", e.InnerText);
d = new System.Xml.XmlDocument();
d.Load(s);
dt = (System.Xml.XmlElement)d.SelectSingleNode("//screen_name");
System.Diagnostics.Process.Start(string.Format("http://twitter.com/#!/{0}", dt.InnerText));
}
catch
{
break;
}
}
}
