OpenGl and XML communicating???

Is there any possible way that I can communicate with openGL using XML as data by use of a xml-rpc or something else.Because we have a project to use xml with external programs and I wanted to use openGL in any possible way, but I can’t figure it out…
Any help link source or advise accept to forget wht I’m trying would be nice

There are non for direct API calls that I know of. I think it would be a really, really bad idea to do programming with XML directly.

Instead, what you probably want to look at is one one of the number of XML file formats that support 3D graphics representations. COLLADA and X3D are probably the two that are worth looking at.
