David,
I have just come across Xpath http://www.w3schools.com/xpath/default.asp
Along with questions in stack overlfow which "suggests" you can use Xpath with XML in R to directly query an XML database without importing.
e.g. http://stackoverflow.com/questions/3876571/how-can-i-use-xpath-querying-usin... and http://stackoverflow.com/questions/4870207/xpath-within-r-using-xml-package
I admit I don't really follow it, but thought I should pass it on in case it was useful.
