[xml] Parsing an in-memory DTD?

["Anne Martens" <Anne Martens Informatik Uni-Oldenburg DE>]

Hi everybody,

I'm writing a program that uses an xml file format for inputs. To validate 
the input, I'd like to use DTDs. Thus, I can warn the user if the used 
input does not validate the file format, and can afterwards be sure that 
the tree I parsed contains all needed elements. As the file format 
shouldn't change, I thought it's best to integrate the DTD in the 
executable, so that I don't have to rely on an external file containing 
the DTD.

To integrate the DTD, I planned to use a static member of the responsible 
class. This member should contain the DTD as a string.

There comes my question: Is there any way to parse a DTD from an in-memory 
string?

I have found the xmlParseMemory function, but as this return a xmlDocPtr, 
it doesn't look suitable.

Having read the following thread, I don't have much hope, but like to ask 
you all anyway:

Thanks a lot in advance,
