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.
