[xml] xmlReaderForMemory question

[Jeremy Enos <jenos ncsa uiuc edu>]

I want to provide a few separate functions which make up my xml interface.

read_file
validate
parse
free_mem

Because these are separate, they'll be called with an argument which is 
a pointer to some data structure that I've read from the file.  Should I 
just hold this data as a char array, or is there a better way already 
built in?  For example, if read_file returns an xmlTextReaderPtr 
pointer, I think I lose the ability to clean up the memory from the char 
array I read in.  Unless xmlReaderForMemory does that as well on 
cleanup?  The API document makes no mention of it.
thanks again for helping a beginner- I hope to accelerate on this before 
long.
