+Summary: System.Xml is throwing an exception where .NET just returns null
+
+Basically I'm in the process of porting a jabber library to mono and I've 
+found a bug in System.Xml, I'm not exactly sure how to explain the 
+problem but basically mono is throwing an exception instead of returning 
+null, which is the desired result.  .NET just returns a null XmlElement 
+in this test case whereas mono throws an exception.
+
+XmlDocument doc = new XmlDocument();
+XmlElement tmpXML;
+
+doc.LoadXml("<iq id='JN_2' type='result' />");
+try 
+{
+    tmpXML = (XmlElement)doc.GetElementsByTagName("query")[0]; 
+    if (tmpXML == null)
+    {
+        Console.WriteLine("This is the desired result.");
+    }
+}
+catch (Exception e)
+{
+    Console.WriteLine(e.Message + "\n\nThis is not the desired result.");
+}
+Console.ReadLine();
+
+Actual Results:
+Throws an exception
+Unhandled Exception: System.ArgumentOutOfRangeException: Argument is out 
+of range
+
+Expected Results:
+Return null.  Tested on .NET, and it returns null.
+
+How often does this happen? 
+Every time.
