I know of prior art on that going back to probably 1995... not exactly  
XPath, but certainly streaming transformations of XML in a server/ 
database environment using something very muck akin to XPath (ie. with  
simple syntax transforms, it would be XPath). There is probably even  
older prior art if you go back to streaming ESIS transformations that  
everyone used to do back in the day...
