The "algorithm" is the expansion of XML entities, which any common 
run-of-the-mill xml parser will do for you.

I think we had this discussion already. This is an XML file and should 
be processed thru an XML parser. If you don't, every little cosmetic 
change to the file structure will break your program. You have been warned.
