[xml] external DTD validation of large XML's

[Jon <jon forums gmail com>]

I am new to the libxml2 api and am looking to use it to create a simple tool that can validate large xml 
files via external DTDs, and eventually XSDs. I've successfully built libxml2 on win7 using a mingw toolchain 
and plan to build the tool as a statically linked exe for windows.

I've found http://mail.gnome.org/archives/xml/2004-July/msg00055.html and 
http://mail.gnome.org/archives/xml/2009-November/msg00039.html and would appreciate pointers in the right 
direction, either sections in xmllint.c to review or ideas on how to use the Reader api to do this.

I'm more concerned about memory usage and speed and have no preference between using the SAX2 or Reader apis.

Thanks,
Jon
