The simple answer is "yes".

The longer answer is: Using which query language, and starting from 
where in the document? Assuming XPath and a global search (which will 
usually not be most efficient solution), one of many ways to express 
this would be

	//Order[Date='2007-09-02' and ../../Sitenum='001507']

See any good XPath tutorial to understand why this works, and what the 
alternatives might be.

If you want to use another query language, see tutorials for that 
language instead, of course.
