Nice.  I downloaded the REXML docs and took a look around.  A question: 
how in the hell would anyone know to use a $ variable in there, and that 
a hash specified as the 4th argument would somehow match a value to that 
variable, when all the docs say is:

match(element, path=nil, namespaces=nil, variables={})
