This is not a question of parsing, it's a question of how you query your
objects after parsing is done. In your example, you got the NPE while
calling oplan.getName(); all you have to do is parse (no NPE will be
thrown here regardless of the Schema and document), then use your
planContext object as you would any other Java object, taking care that
some of the fields may be null.

Actually,
Let me rephrase the question:
if I am reading in a bunch of documents that I am trying to parse.
Not all of them will have the same data fields filled in. How will I be
able to still parse without getting the nullpointer exception if a
particular field is blank?

Hello,
as far as I can see you schema doesn't define a namespace, so how should
XMLBeans know which schema to use?
Try to specifiy a namespace or use the special 'noNamespace'
namespace in your XML instance.
