Hi,

	I use a JavaCC Grammar to parse a DTD. I wrote it myself, or stricly
speaking, copied it from the XML Specs. It works, but fails in rare
cases.
My proggy is not open source, but get the grammar at
http://www.jnerd.de/sneak/DTDParser.jj . 
This is the raw version of the grammar (the one I use in XML2Java (
http://www.jNerd.de/xml2java.html )). I didn't edited the line you do
not need. But maybe it is a better example how to use it then.

There are certain restrictions though. The grammar does not accept
comment. I filter them before pipeing the stream to the parser.

Note that you need JavaCC2.0 (
http://www.webgain.com/products/metamata/zip_files/JavaCC2_0.zip ) for
building the code.

Use the grammar freely, but please report any bugs, enhancements or
comments ( mailto:DTDGrammar@j... ).

I hope it helps you.

CU,

	PAtrick
