Description eb1 2012-04-30 10:11:45 UTC
Consider the following code snippet:

string xml = "<root><one><two>A<three>B</three>C</two></one></root>";

var doc = XElement.Parse(xml);
var it = otherDoc.CreateNavigator().Select("//one");
var one = it.Current;
var three = one.Select("two/three");

Expected Output:

Actual Output:
NullReferenceException because three.Current is null.

I cannot really reproduce the issue. If you are seeing problem with related to XPath but not from the exact code shown above, we need a reproducible code.
