Create the Headers and Source Files for SaxJumpStart

[アーティクル]
10/27/2016

In this topic, you will create the remaining headers and source files for the SaxJumpStart application. Create each file in Visual Studio, copy the code, and paste it into the file.

One of the most important activities when creating a Simple API for XML (SAX2) application is to implement handler classes. This example implements a ContentHandler that is derived from the ISAXContentHandler interface. The ContentHandler is implemented in MyContent.cpp.
