Expat lib and Pthreads

Greetings list,

I have fully working parsing module and I need to use this module with 
two threads (C pthread library) to parse different xml documents 
simultaneously.
Both threads will launch:

XML_Parser parser = XML_ParserCreate(NULL);
XML_SetElementHandler(parser, _start_hndl, _end_hndl);
XML_SetCharacterDataHandler(parser,_char_hndl );

Will I have inconsistency if both threads will use _start_hndl() and 
_end_hndl() handler functions?

Thanks!
