+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(&quot;&lt;iq id='JN_2' type='result' /&gt;&quot;);
+try
+{
+ tmpXML = (XmlElement)doc.GetElementsByTagName(&quot;query&quot;)[0];
+ if (tmpXML == null)
+ {
+ Console.WriteLine(&quot;This is the desired result.&quot;);
+ }
+}
+catch (Exception e)
+{
+ Console.WriteLine(e.Message + &quot;\n\nThis is not the desired result.&quot;);
+}
+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.
