You are using ANTLR 3.1 for a grammar which requires ANTLR 2.7.7 (or
earlier). As ANTLR 3 uses a new syntax this can't work. Your options are
either to switch back to an earlier version of ANTLR or to convert the
grammar to 3.1. There is a tool which does some of the work, but if you
have no knowledge of both versions it may be easier - when choosing the
second option - to create a 3.1 grammar from scratch. There is a
tutorial on parsing XML and a project to parse XQuery, which may be
helpful in that endeavor.
