Hi Norm, I was planing on using SAX instead of DOM since everything I read said that DOM had significant overhead when compared to SAX. And the requirement here is speed above all else. (And the Java code I'm implementing in C++ was written using SAX as well.)
So I guess my real question is this. Even though Java uses DefaultHandler for SAX, does the C++ version of this library support using the DefaultHandler for SAX?
