Today, just for fun, I tried similar code in C# Forms rather than C#
ASP.NET but it again skips every other node (even nodes), just like in
ASP.NET.  Thus only first names Rob1 and Rob3 are being read back from
the XML file, but not Rob2.  Strange how only Rob2 shows up in
Debug.Writeline, see below.

Too bad, as this "short way" would have been nice.  Strange but in
console mode I don't have any problems.  One possible problem: perhaps
in C# when </MyEmployee> is encountered, somehow the node skips?  But
why not this problem in Console mode?

BTW, do...while does not seem to affect things differently (rather
than just while) nor does .localname vs .name
