Thanks for the help guys.  I used:

(//register[@status  ='direct' 
or @status='reserve'])[1]

and it worked like a charm.  I also changed self::* to . for readability sake.

Is there a difference between them -- for example, does one of them take a couple more processing steps to understand it? 

Thanks again

The XPath "//register[@status  ='direct' or @status='reserve'][1]" will 
return you all the register elements with status equal "direct" or 
"reserve" that are the first  such child elements of their parents.

To get the first one in the document, use "(//register[@status  ='direct' 
or @status='reserve'])[1]".

But I'd do it JP's way and use the preceding:: axis.
