Hi,
Is there any readily available XML parsing library in C that I can use in a driver? I am having issues with trying to use Expat because it uses realloc.
Regards,
Mridul.
None that I know of; why would you need to do this in a driver?
You could, btw, reimplement malloc/realloc/calloc/free against the pool allocator (choose the pool that is appropriate for your application).

You can always implement a realloc primitive; it isn’t that hard.

Can you parse XML in user mode and only supply the parsed binary results to the kernel mode?

Written in c++ => no go for most kernel mode projects.
( no intention to start another spin of the discussion ).
Does the OP need a xml parser ‘per se’, or just a way to
share text files between their driver and apps?
Don’t throw boots at me please.
A simple INI file is *way* more readable and easy than xml.
We’ve made a parser for ini files, in plain C, small, simple and robust.

I’ve used this parser also (in user mode, folks, don’t freak out) as part of a DLL I support. VERY solid and relatively well written.
IIRC, it’s only nominally in C++ and would be relatively straight-forward to convert to vanilla C. Of course, that would still be a project.

Unfortunately xml has sort of become pervasive for embedded systems and
consequently has cascaded up into os drivers for those systems. I agree with
you regarding simpler ‘ini’ files, although at least xml is sort of
standardized. Also you can’t just toss “C++ no go” and then try to immunize
yourself with a ‘not trying to start a flame war’. If you are not trying to
start a flame war leave your opinions about C++ out of the discussion.

Just to clarify, I am not passing any information from user mode, nor am I using any XML files as INI files. I have a pre-existing XML file which I need to parse in my driver.
I have reimplemented realloc using ExAllocatePoolWithTag to get Expat working.
Thanks for the replies.

Mridul.
