[Expat-discuss] Text data handler

[Shen, Lin]

I want to parse multiple documents one by one.
What I'm doing right now is to call XML_ParseCreate() once at the very beginning, and then call XML_Parse() for each document. I've tried setting the 4th parameter to both FALSE and TRUE, but always get "junk after document element at line" error when the second document gets fed into the parser.  

Thanks
