Thanks David.  I've done dir and help on sources, filters, and many of
the member functions/variables.

I did find that sources.XMLStructuredGridReader has a
GetDataInformation() member, and inside of that a DataInformation
variable that has a number of members that indicate that it has loaded
my data, but I'm still unable to find any member functions that can
retrieve the values of my data at particular grid points.

Any help would be appreciated.

Thanks,

Mark
