This is obtuse. Using the tree representation of an XML parser is
equivalent to using the tree representation of a recursive descent
parser.
You do not have to write the lexer, parser, tree representation or
lookup functions ( XPATH ) if you use XML.
You have to write the lexer ( flex ), parser ( bison ), tree
representation format, lookup features if you use a recursive descent
parser.
BTW, I am writing a recursive descent parser because everyone here seems
to hate XML. Does anyone have the bison rules already written out
(sharign would be *greatly* appreciated)? Or am I the first one?
Thanks,
Bob Rossi
