XML on TPF: A Short Tutorial — Page 2 of 10
Scenario
Paul is a TPF application programmer and has been asked to put together a demonstration of how a TPF application written
in C++ language can interact with XML data. Paul decides to create some sample XML data and then write an application
that will display that data. Although most applications will do more with XML data than simply display it,
Paul wants his application to show the basics of interacting with XML data on TPF. His application
shows how to do each of the following:
Use the DOM API with validation against a DTD or XML Schema
Use the DOM API without validation
Use the SAX API with validation against a DTD or XML Schema
Use the SAX API without validation.
XML data is presented through elements and attributes that, together, create an XML document. Paul needs to
create some sample XML data for his application to interact with. He creates both a DTD and XML Schema document, both of which define all the allowable elements and attributes (as well as the structure of those elements and attributes) using different syntax. He also creates two XML documents: one that is based on the DTD and one that is based on the XML Schema. Paul is already familiar with the
necessary syntax for writing DTDs, XML Schemas, and XML documents.
