Always try to use only the standard XML APIs when writing XML applications. This will keep your application shielded from changes in the underlying implementation of those standard APIs and also gives you more flexibility to change the implementation of the standard pieces without modifying your application code.
If you need functionality that is not available in the standard APIs like DOM and SAX, then perhaps using the Xerces Native Interface (XNI) will provide the information to build the appropriate parsing tools for your application. For more detailed information regarding XNI, refer to the XNI Manual.
