Re: Accessing "external" tables from within LuaExpat callbacks

[Michael Bauroth <Michael.Bauroth@...>]

Ok, to make the question simpler ... :)

I want to fill an table (local or global ) through reading a XML file 
with use of LuaExpat. Has eventually somebody a short example to do 
that? Any help is highly appreciated.

Best Regards
Micha
