I can't send the article yesterday, I wrote today.
When using the function XML_setUserData () in EXPAT, it says this sets the user data point gets passed to handlers. I don't know the function
Start (Void * Data, Const Char * EL, Const Char ** Attr),
Void char_hndl (Void * Data, Const Char * TXT, INT TXTLEN),
Void End (Void * Data, Const Char * EL);
The DATA is
Pointer USERDATA in XML_SETUSERDATA (XML_PARSER P, VOID * UserData)??
