The REX parser
|
|
|
|
xmlformat contains code based on the REX parser, which is Copyright (c) 1998,
|
|
Robert D. Cameron. REX is described in this document:
|
|
|
|
http://www.cs.sfu.ca/~cameron/REX.html
|
|
|
|
The document contains a Perl implementation of REX:

The Perl and Ruby implementations of xmlformat contain parsers that
|
|
are based on the preceding code and are essentially the same, with the
|

exception of changes to variable and function names.
