Based on your question I just took a look at
Expat and saw a mix of calls in xmlparse.h,
some using strings that are null terminated,
some that are not:
/* s is not 0 terminated. */
typedef void (*XML_CharacterDataHandler)(void *userData,
const XML_Char *s,
int len);
/* target and data are 0 terminated */
typedef void (*XML_ProcessingInstructionHandler)(void *userData,
const XML_Char *target,
const XML_Char *data);
/* data is 0 terminated */
typedef void (*XML_CommentHandler)(void *userData, const XML_Char *data);
Now this was a quick look and I could be poking
around in the wrong file, please point me
it the right direction if that's the case.
Thanks,
-joe
